Do I need FDA approval to sell a salicylic acid body serum?

Whether you need FDA approval depends entirely on the claims you make on the label and in your marketing. Salicylic acid body serums can be regulated as either cosmetics or OTC drugs in the United States — and the line between them is determined by your claims, not by the ingredient itself.

If your label and marketing say nothing about treating or preventing acne, reducing blemishes, unclogging pores, or affecting the structure or function of skin in a therapeutic way, the product is likely a cosmetic. Cosmetics do not require FDA pre-market approval. You must comply with cosmetic labeling regulations (21 CFR Part 701), use only approved colorants, and ensure your manufacturing facility follows voluntary cGMP (though FDA has been pushing for mandatory cGMP under the Modernization of Cosmetics Regulation Act of 2022, or MoCRA). MoCRA now requires facility registration and product listing for cosmetics sold in the US, which took effect in 2024 — confirm your manufacturer is registered.

If your label says the product treats acne, reduces acne breakouts, or prevents pimples, you are making a drug claim. Salicylic acid at 0.5–2% for acne is covered by the FDA OTC acne monograph (21 CFR 333), meaning you do not need a New Drug Application — but you do need to follow the monograph exactly: correct concentration range, mandatory Drug Facts panel, approved inactive ingredients, and manufacturing in an FDA-registered OTC drug facility under 21 CFR Part 211 cGMP. Failure to follow the monograph converts your product into an unapproved new drug, which is a serious compliance risk.

In practice, most indie founders launching a salicylic acid body serum choose cosmetic positioning — describing it as an exfoliating, smoothing, or clarifying serum — to avoid the OTC drug compliance burden. This is legally valid as long as marketing copy doesn't slip in drug claims. Be especially careful with social media posts and influencer briefings, which FDA considers part of your product's labeling context.

In the EU, there is no OTC drug monograph equivalent for salicylic acid. Body leave-on products with salicylic acid up to 2% are regulated as cosmetics under EU Regulation 1223/2009, but require a mandatory safety assessment (CPSR) completed by a qualified toxicologist and a Product Information File (PIF). The finished product must also carry a "not for use on children under 3" warning.
