Introduction
Cosmetic advertising is one of the most sensitive areas of consumer advertising in Turkey. Cosmetics are used directly on the human body, often on the skin, hair, nails, lips, teeth or external intimate areas. Consumers purchase cosmetics not only for appearance, but also for confidence, hygiene, personal care, anti-aging expectations, acne concerns, hair loss anxiety, skin sensitivity, pigmentation, body image, beauty standards and social perception. Because of this close connection with personal health and appearance, cosmetic advertisements can strongly influence consumer behavior.
The subject of advertising law for cosmetics in Turkey is especially important for cosmetic brands, importers, manufacturers, distributors, e-commerce sellers, marketplaces, beauty clinics, pharmacies, influencers, advertising agencies, social media managers and foreign companies targeting Turkish consumers. A cosmetic advertisement may appear on television, Instagram, TikTok, YouTube, Google Ads, e-commerce marketplaces, product packaging, websites, mobile applications, influencer videos, consumer reviews, before-after visuals or in-store displays.
Turkish law does not prohibit cosmetic advertising. However, cosmetic advertisements must be truthful, verifiable, transparent, fair and consistent with the legal nature of cosmetic products. A product marketed as a cosmetic must not be advertised as if it were a medicine, medical device or treatment. Claims such as “cures acne,” “treats eczema,” “prevents hair loss,” “removes wrinkles permanently,” “heals skin disease,” “clinically proven to treat,” or “dermatologist-approved medicine effect” may create serious legal risk if they go beyond cosmetic functions.
The main legal framework includes Law No. 6502 on the Protection of Consumers, the Regulation on Commercial Advertising and Unfair Commercial Practices, Law No. 5324 on Cosmetics, the Cosmetic Products Regulation, TİTCK guidance on cosmetic product claims, distance sales rules, electronic commerce rules, commercial electronic message rules and KVKK data protection rules. TİTCK lists the Cosmetic Law, the Cosmetic Products Regulation published in the Official Gazette on 8 May 2023, and the Cosmetic Product Claims Guide among the key legal sources for the cosmetics sector.
This article explains the key rules on cosmetic advertising in Turkey, including cosmetic product claims, prohibited health claims, substantiation, “dermatologically tested” statements, ingredient claims, before-after visuals, influencer advertising, environmental claims, consumer reviews, e-commerce listings, targeted advertising, children’s advertising, price claims and Advertising Board sanctions.
What Is a Cosmetic Product Under Turkish Law?
Before assessing cosmetic advertising, the product must first be correctly classified. A cosmetic product is generally intended to be applied to the external parts of the human body, teeth or oral mucosa for purposes such as cleaning, perfuming, changing appearance, protecting, keeping in good condition or correcting body odors. Products such as creams, shampoos, deodorants, perfumes, make-up products, toothpastes, hair dyes, sunscreens, skin care products and nail products may fall within the cosmetic category if their function remains cosmetic.
Correct classification matters because advertising must match the product’s legal category. A cosmetic product cannot be marketed as if it were a medicine. If the advertisement claims that the product treats disease or has pharmacological, immunological or metabolic effects, the product may no longer be perceived as a cosmetic. This creates both advertising risk and product classification risk.
TİTCK expressly warns that, before making an application concerning cosmetic products, firms should examine the relevant legislation and should not apply as cosmetics for product groups that are not compliant with cosmetic legislation.
This means advertisers should not start with marketing language and then try to fit the product into the cosmetic category. The correct approach is the opposite: first determine the product’s legal classification, then design claims that remain within the permitted cosmetic scope.
Main Legal Authorities
Two public authorities are particularly relevant in cosmetic advertising.
First, the Turkish Medicines and Medical Devices Agency, known as TİTCK, regulates cosmetic product legislation, product notifications, safety, product information files, adverse effect notifications and cosmetic product claims. TİTCK’s cosmetics page states that cosmetic products must be notified to the Ministry before being placed on the market and refers to the Product Tracking System, known as ÜTS.
Second, the Advertising Board, known as the Reklam Kurulu, supervises commercial advertisements and unfair commercial practices. The Ministry of Trade states that advertisements must be correct and honest, must not mislead consumers or exploit their lack of knowledge and experience, and must not endanger public health or exploit vulnerable groups.
Cosmetic advertising therefore sits between product regulation and advertising regulation. TİTCK rules determine what the cosmetic product may claim, while the Advertising Board may sanction misleading, hidden, unsubstantiated or unfair advertisements directed at consumers.
General Advertising Principles for Cosmetics
Cosmetic advertisements must comply with general advertising law. They must be honest, accurate, clear and not misleading. They must not exploit consumer vulnerability, fear, lack of knowledge, body image anxiety or health concerns. They must not create the impression that the product has medical effects if it does not.
The Ministry of Trade also states that hidden advertising is prohibited in all communication channels, that subtitles and footnotes must be readable, and that advertisements for products including cosmetics must comply with their own sector-specific advertising and promotion rules.
This is particularly important for cosmetics because material information is often hidden in small disclaimers. For example, a headline may say “removes wrinkles,” while the fine print says “appearance of fine lines may be reduced with regular use.” If the headline creates a stronger claim than the evidence supports, the disclaimer may not be enough.
Similarly, a cosmetic advertisement should not use scientific-looking language to create exaggerated trust. Expressions such as “clinically proven,” “medical grade,” “doctor recommended,” “pharmaceutical technology,” “stem cell effect,” “DNA repair,” “anti-inflammatory,” or “treats acne” must be reviewed carefully.
TİTCK Cosmetic Product Claims Guide
The TİTCK Cosmetic Product Claims Guide is a central compliance source. The current guide explains that it was prepared to guide manufacturers, importers, distributors, promoters, responsible persons, media organizations and intermediaries on matters to be considered in cosmetic product claims. It also states that the responsible person must ensure that the claim complies with the relevant documentation.
The guide defines a claim broadly. A claim includes information, statements or visuals used on the product label, packaging or promotional materials concerning the product’s characteristics, effectiveness or safety. This means claims are not limited to written slogans. Images, before-after photos, symbols, badges, videos, influencer statements, website descriptions and marketplace tags may also be claims.
The guide identifies six common criteria for cosmetic product claims:
Legal compliance.
Truthfulness.
Supporting evidence.
Honesty.
Fairness and competition.
Informed decision-making.
These criteria are equal in importance and apply to cosmetic claims generally.
For advertisers, the practical meaning is clear: every cosmetic claim should be legally permitted, factually accurate, supported by evidence, fairly presented and understandable for the average consumer.
Cosmetic Claims Must Be Supported by Evidence
Substantiation is one of the most important rules in cosmetic advertising. TİTCK’s guide states that evidence supporting direct or indirect cosmetic product claims must include expert evaluations and must be sufficient and verifiable. It also states that claims must be supported by appropriate and adequate scientific evidence, and that studies used for substantiation must be relevant to the cosmetic product and the claimed effect, ethically conducted and based on well-designed and validated methods.
This requirement applies to common cosmetic claims such as:
“48-hour hydration.”
“Reduces the appearance of wrinkles.”
“Improves skin elasticity.”
“Helps even skin tone.”
“Strengthens hair appearance.”
“Controls oiliness.”
“Protects against UV rays.”
“Dermatologically tested.”
“Suitable for sensitive skin.”
“Hypoallergenic.”
“Clinically tested.”
“Non-comedogenic.”
A claim should not be used merely because competitors use similar language. The brand should have product-specific evidence. If the formula changes, the brand should ensure that the evidence still supports the claim.
The guide also warns that in vitro or in silico results should not be presented as suggesting an in vivo result. This is important because cosmetic brands often rely on laboratory tests, ingredient studies or theoretical mechanisms. An ingredient study does not automatically prove the final product’s advertised effect on human users.
Prohibited Medical and Treatment Claims
The biggest risk in cosmetic advertising is crossing the line into medical or therapeutic claims. A cosmetic product may clean, perfume, protect, improve appearance or keep the body in good condition. It should not be advertised as treating disease, healing medical conditions or producing drug-like effects.
Risky claims include:
“Treats acne.”
“Cures eczema.”
“Prevents psoriasis.”
“Stops hair loss.”
“Regrows hair.”
“Heals wounds.”
“Eliminates fungal infection.”
“Treats dermatitis.”
“Removes scars permanently.”
“Repairs skin disease.”
“Provides Botox effect.”
“Medical treatment for pigmentation.”
Such claims may mislead consumers and may also suggest that the product is not a cosmetic but a medicinal or medical product. Cosmetic brands should use appearance-based wording where legally supportable. For example, “helps reduce the appearance of blemishes” may be safer than “treats acne,” if supported by evidence and if the overall impression remains cosmetic.
The Ministry of Trade states that advertisements for cosmetics must comply not only with general advertising rules but also with the relevant sector-specific legislation. Therefore, cosmetic advertisers should review both advertising law and cosmetic product legislation before publishing health-related language.
“TİTCK Approved,” “Ministry Approved” and ÜTS Claims
Another major risk is using public authority references as marketing tools. TİTCK’s Cosmetic Product Claims Guide states that claims, visuals or similar references saying that a cosmetic product is approved or permitted by the Ministry of Health or the Agency cannot be used on labels, packaging or promotional materials. It also states that claims such as “our product complies with cosmetic legislation” or “has ÜTS notification” are not permitted, because compliance and notification are legal requirements rather than special advantages.
This is very important in practice. Many cosmetic sellers attempt to create consumer trust by saying:
“Ministry approved.”
“TİTCK approved.”
“ÜTS registered.”
“Government approved.”
“Legal product.”
“Approved cosmetic product.”
Such expressions may mislead consumers because they imply a special endorsement, quality guarantee or official approval. The fact that a product has been notified or is subject to the regulatory system should not be used as a superiority claim.
Ingredient Claims
Cosmetic advertising frequently emphasizes ingredients. Claims such as “contains hyaluronic acid,” “with vitamin C,” “retinol complex,” “aloe vera,” “snail extract,” “collagen,” “tea tree oil,” “niacinamide,” “salicylic acid,” “keratin,” or “natural oils” may influence consumer decisions.
Ingredient claims must be accurate. TİTCK’s guide states that if a product claims to contain a specific ingredient, that ingredient must actually be present. It gives examples such as a product expressly claiming to contain honey needing to contain honey rather than only honey aroma, and a “snail extract” claim not being satisfied merely by the presence of allantoin.
The guide also states that if a product refers to the properties of a specific ingredient but the finished product does not have those properties, the advertisement should not imply that the finished product has them. For example, if the product does not have a moisturizing effect, a “moisturizing aloe vera” claim or prominent aloe vera visual would not be appropriate.
The practical rule is that ingredient marketing should not exaggerate the final product’s effect. A product may contain a trendy ingredient, but the brand must not imply a benefit unless the finished formula supports that benefit.
“Free From” Claims
“Free from” claims are very common in cosmetics. Examples include “paraben-free,” “silicone-free,” “alcohol-free,” “hydroquinone-free,” “SLS-free,” “fragrance-free,” or “preservative-free.”
These claims can be lawful when accurate and not misleading. However, they may become unlawful if they imply superiority based on the absence of an ingredient that is legally prohibited or normally absent, or if they create fear about legally permitted ingredients.
TİTCK’s guide states that legal requirements, such as not containing a prohibited substance or complying with cosmetic legislation, should not be used as a product advantage. It gives the example that “does not contain hydroquinone” is not permitted because hydroquinone is already prohibited under cosmetic legislation.
Therefore, “free from” claims must be assessed carefully. A claim should not mislead consumers into believing that competing products are unsafe or unlawful merely because they contain legally permitted ingredients.
“Hypoallergenic,” “Dermatologically Tested” and Similar Claims
Claims such as “hypoallergenic,” “dermatologically tested,” “suitable for sensitive skin,” “clinically tested,” “non-comedogenic,” and “ophthalmologically tested” are powerful because they suggest safety, expert evaluation and reliability.
Such claims should be supported by appropriate evidence. The claim should match the test actually performed. For example, “dermatologically tested” should not be used if there is no relevant dermatological evaluation. “Hypoallergenic” should not be used if the product contains ingredients commonly associated with allergic reactions without adequate justification.
These claims should also not imply a medical guarantee. “Dermatologically tested” does not mean “approved by dermatologists as a treatment.” “Hypoallergenic” does not mean that no consumer can ever experience an allergic reaction. If conditions or limitations exist, the advertisement should not hide them.
Before-and-After Images
Before-and-after visuals are widely used in skincare, hair care, anti-aging, acne appearance, pigmentation, slimming-looking cosmetic products and beauty treatments. They are also high-risk.
TİTCK’s guide states that product performance claims should not go beyond existing supporting evidence and that electronically manipulated before-after images should not be relied upon if the image misleads about the product’s performance.
This means cosmetic brands should not use lighting, filters, make-up, angle changes, retouching, AI editing or unrelated treatment results to exaggerate product effects. If a before-after visual is used, the conditions should be transparent: duration of use, method of use, whether other products were used, whether results are typical, and whether the image has been altered.
Influencer before-after content is also risky. A brand cannot avoid responsibility by asking an influencer to publish exaggerated results. If the influencer content is sponsored or commercially connected, the brand should review claims and visuals.
Superiority Claims: “Best,” “Most Effective,” “Unique”
Cosmetic advertisements often use superiority language. Examples include “the best anti-aging cream,” “most effective serum,” “unique formula,” “number one,” “strongest solution,” “miracle effect,” or “unmatched results.”
TİTCK’s guide warns that claims for cosmetic products with the same characteristics should not imply superiority through expressions such as unique, unmatched, best or most effective. It also states that new formulation claims should reflect real improvement and should not be exaggerated.
Superiority claims are risky unless they are objective, verifiable and not misleading. If a product claims to be “number one,” the basis must be clear: number one in sales, consumer preference, dermatologist recommendation, market share or another measurable category. The geography and time period should also be clear.
Vague superiority claims may be treated as exaggeration in some cases, but when they influence consumer decisions or appear scientific, evidence may be required.
Influencer Advertising for Cosmetics
Influencer marketing is one of the most common cosmetic advertising channels in Turkey. Influencers promote skincare routines, make-up products, hair care products, perfumes, sunscreens, anti-aging creams and beauty devices through videos, reels, stories, live broadcasts, discount codes and affiliate links.
The 2026 amendments to Turkish advertising rules require social media influencers to clearly indicate advertising nature with expressions such as “advertisement” or “promotion” when they receive benefits such as earnings, discounted products or services, or event participation.
For cosmetic brands, influencer compliance has two parts. First, the commercial relationship must be disclosed. Second, the cosmetic claims must be lawful. An influencer should not make medical claims, exaggerate results, use misleading filters, imply guaranteed results or present a product as personally experienced if they have not actually used it.
Brands should provide influencers with approved claim language. Influencer agreements should prohibit unauthorized health claims, misleading before-after visuals, undisclosed filters, fake personal experiences and hidden advertising.
Cosmetic Advertising on E-Commerce Platforms
Cosmetics are heavily sold through e-commerce platforms and online marketplaces. Product titles, descriptions, images, reviews, badges, filters and Q&A sections may all function as advertisements.
E-commerce sellers should not use prohibited claims in product listings. Claims such as “cures acne,” “medical cream,” “eczema treatment,” “hair regrowth,” “botox effect,” or “permanent wrinkle removal” may create risk. Marketplace Q&A sections should also be monitored because sellers may make risky claims in answers to consumer questions.
Consumer reviews are another important issue. The 2026 advertising amendments provide that consumer reviews obtained from platforms where purchase verification is not possible may not be published, and that different review categories such as product, service, delivery, seller or provider must be shown clearly and accessibly in the same area.
This matters for cosmetic advertising because reviews often contain strong product claims. A brand should not manipulate reviews, publish fake testimonials, import unverifiable reviews or highlight only extreme positive results.
Environmental and Natural Claims in Cosmetic Advertising
Cosmetic brands frequently use environmental and natural claims such as “eco-friendly,” “green,” “clean beauty,” “natural,” “organic,” “cruelty-free,” “vegan,” “biodegradable,” “sustainable packaging,” “reef safe,” or “carbon neutral.”
The 2026 amendments prohibit broad environmental claims such as “environmentally friendly” without explanation. They also require environmental claims to specify the relevant life-cycle stage and require certificates or approvals to be substantiated with documents from competent institutions, universities, accredited bodies or independent testing and evaluation organizations.
For cosmetics, this means green claims should be specific and evidence-based. “Eco-friendly product” is riskier than “bottle contains 50% recycled plastic,” if the latter is true and documented. “Natural” should not be used if the product’s composition or consumer impression makes the claim misleading. “Organic” should be supported by valid certification where applicable.
Targeted Advertising and Cosmetics
Cosmetic brands often use targeted advertising based on age, gender, browsing behavior, purchase history, skin care interests, abandoned carts, influencer engagement or location. Targeted advertising can be lawful, but it must comply with advertising transparency and KVKK.
The 2026 amendments state that advertisers may conduct targeted advertising based on online behavior and personal data analysis if they provide consumers with direct and easily accessible information about the criteria used to show the advertisement and how those criteria can be changed. The same amendments prohibit targeted advertising directed at children through profiling based on personal data.
Cosmetic brands should be careful not to exploit vulnerabilities. Targeting acne products, anti-aging creams, weight-related cosmetic products or hair loss-related products may affect consumers with body image concerns. The advertisement should not shame consumers or pressure them through fear-based messaging.
Children and Teen Consumers
Cosmetic advertising may reach children and teenagers through social media, influencers, gaming apps, short videos and beauty trends. Young consumers may be especially vulnerable to body image pressure, acne anxiety, skin tone concerns and influencer persuasion.
Cosmetic advertisements directed at minors should avoid messages that exploit insecurity. They should not suggest that beauty products are necessary for social acceptance. They should not use profiling-based targeted advertising directed at children. They should not encourage unsafe use of products.
If a product is unsuitable for children or teenagers, advertising should not be designed to appeal to them. Influencer campaigns should also consider the audience demographics.
Price, Discount and Campaign Claims
Cosmetic brands frequently use discount advertising. Examples include “50% off,” “buy one get one free,” “limited-time set,” “Black Friday beauty sale,” “free gift,” “member price,” “influencer code,” and “only today.”
The 2026 amendments provide that conditional sales advertisements providing discounts or other benefits are subject to discount advertising rules, and that in discount advertisements the lowest price applied in the last ten days before the discount start date may be shown as the pre-discount price for ordinary goods.
This is highly relevant to cosmetics because online beauty campaigns often use crossed-out prices, bundles and influencer discount codes. Brands should not inflate previous prices before a campaign. “Free gift” should not be misleading if the product price has been increased. “Limited time” should reflect a real campaign period.
AI-Generated Cosmetic Advertising
AI-generated models, virtual influencers, synthetic skin images, AI before-after visuals and digital beauty advisors are increasingly used in cosmetic advertising. These tools create legal risk if consumers believe artificial content is real.
The 2026 amendments require clear disclosure where advertisements use AI-generated digital characters that cannot be distinguished from real humans. They also prohibit advertisements where an AI-generated digital copy of a real person creates the impression that the person personally experienced or recommended a product or service.
For cosmetics, this rule is important because visual appearance is central. AI should not be used to fabricate skin results, fake testimonials, synthetic consumer reviews or virtual experts without disclosure.
Advertising Board Sanctions
Misleading cosmetic advertisements may lead to Advertising Board sanctions, including suspension, correction, administrative fines, temporary suspension and access blocking for online content. The Ministry of Trade states that the Advertising Board is authorized to examine advertisements and unfair commercial practices, issue suspension or correction decisions, impose administrative fines and decide access blocking for unlawful online advertisements.
For 2026, administrative fines for misleading advertisements and unfair commercial practices may range from 99,339 TL to 39,916,524 TL, depending on factors such as the nature of the violation, benefit obtained, harm caused, fault, economic condition of the violator and advertising medium.
The Ministry has also stated that the Advertising Board closely monitors health-claim advertisements involving consumer-facing products such as food supplements and cosmetics, especially where seasonal or health-related consumer concerns are exploited.
Practical Compliance Checklist for Cosmetic Advertising
Cosmetic brands and sellers should apply the following checklist:
Confirm that the product is legally a cosmetic.
Avoid treatment, cure, disease prevention and medical claims.
Do not use “Ministry approved,” “TİTCK approved,” or “ÜTS registered” as advertising advantages.
Ensure every claim is supported by sufficient and verifiable evidence.
Check that ingredient claims match the final product formula.
Do not imply that an ingredient gives the finished product an effect unless proven.
Avoid misleading “free from” claims.
Substantiate “hypoallergenic,” “dermatologically tested,” and “clinically tested” statements.
Avoid manipulated before-after visuals.
Do not use filters or AI to exaggerate results.
Disclose influencer partnerships clearly.
Provide influencers with approved claim language.
Monitor marketplace listings and Q&A sections.
Verify consumer reviews.
Do not publish unverifiable or fake testimonials.
Make environmental claims specific and documented.
Comply with discount advertising rules.
Avoid profiling-based targeted ads directed at children.
Preserve evidence, test reports, screenshots, influencer contracts and campaign approvals.
Conclusion
Advertising law for cosmetics in Turkey requires careful compliance because cosmetic products directly affect consumers’ appearance, self-perception and health-related concerns. Cosmetic advertising is permitted, but claims must remain within the cosmetic function of the product. A cosmetic advertisement should not turn a cosmetic product into a medicine, treatment or medical solution through exaggerated claims.
TİTCK’s Cosmetic Product Claims Guide provides the key claim principles: legal compliance, truthfulness, supporting evidence, honesty, fairness and informed decision-making. It also makes clear that cosmetic claims must be supported by sufficient and verifiable evidence, and that public authority approval claims such as Ministry approval, TİTCK approval or ÜTS notification should not be used as promotional advantages.
The Ministry of Trade’s general advertising rules add another layer: cosmetic advertisements must be correct, honest, non-misleading, readable, not hidden, and compliant with sector-specific legislation. The 2026 digital advertising amendments further strengthen rules on influencer disclosure, targeted advertising, children’s profiling, AI-generated advertisements, discount advertising, environmental claims and consumer reviews.
For cosmetic businesses operating in Turkey or targeting Turkish consumers, the safest principle is evidence-based transparency. Do not promise treatment. Do not exaggerate results. Do not hide sponsorship. Do not manipulate before-after images. Do not use official notification as a marketing claim. Do not publish unsupported “best,” “most effective,” “natural,” “hypoallergenic,” or “dermatologically tested” statements. Do not exploit consumer insecurity.
A compliant cosmetic advertising strategy protects consumers, reduces regulatory risk and strengthens brand trust. In Turkey’s beauty and personal care market, long-term credibility depends not only on persuasive visuals and influencer reach, but also on lawful, honest and scientifically supported communication.
