Acne Skincare Private Label FAQ

What active ingredients are used in private-label acne skincare?

The main families are salicylic acid, benzoyl peroxide, azelaic acid, and retinoids such as retinol. Each works by a different mechanism — salicylic acid exfoliates inside the pore, benzoyl peroxide targets acne bacteria, azelaic acid calms and evens tone, and retinoids normalize cell turnover.

What is a safe concentration of salicylic acid in a cosmetic?

Below roughly 2%, salicylic acid can sit in a cosmetic formula if the brand avoids drug claims; at acne-treatment positioning it enters the US OTC drug monograph range of 0.5–2%. In the EU, salicylic acid is a restricted ingredient, capped at 2% in leave-on cosmetics under Annex III of the Cosmetics Regulation, with labeling conditions for some products.

Is benzoyl peroxide allowed in cosmetics?

Not in the EU — benzoyl peroxide is prohibited in cosmetic products there and is treated as a medicine. In the US it is an OTC drug active for acne at 2.5–10%, not a cosmetic ingredient. Brands should confirm which regime applies to their target market before formulating.

What percentage of retinol should an acne or blemish product use?

For a private-label cosmetic entry, roughly 0.1–0.3% retinol is a sensible starting range. Higher levels multiply irritation and oxidation risk without a proportional claim advantage. Retinol supports the cell-turnover story of an acne routine, but visible "anti-acne" claims may push the product toward drug status depending on the market.

How do I prevent an acne formula from irritating skin?

Manage the irritation curve in the vehicle: keep leave-on formulas light and non-occlusive, add soothing and barrier-support actives such as niacinamide, panthenol, allantoin, and glycerin, and consider a rinse-off cleanser vehicle for sensitive users. Acne actives work by controlled exfoliation, so the formula's job is delivering the active while keeping the user comfortable enough to stay compliant.

Is an acne-treatment product a cosmetic or a drug?

It depends on the market and the claims. In the US, intended use decides the class: products marketed to treat acne — including those using monograph actives such as benzoyl peroxide or salicylic acid at treatment levels — carry OTC drug obligations. In the EU, acne-treatment positioning with cosmetic ingredients is limited to cosmetic claims, and drug-level actives such as benzoyl peroxide are excluded from cosmetics entirely.
