Overview
Cos De BAHA's Niacin serum is a dropper-format formula in a 60 milliliter bottle, listed to address acne, wrinkles, added vitamins and UV concerns. It is offered in fragrance free and fresh scent variants.
The Niacin name points to niacinamide as the likely core ingredient, though the listing doesn't spell out a concentration or a full ingredient list beyond the concerns it addresses. Its UV protection claim is listed as an addressed concern rather than a measured SPF, so it shouldn't be treated as a stand-in for daily sunscreen.
- 60 ml dropper serum
- Addresses acne, wrinkles, UV concerns
- Fragrance free or fresh scent options
- Niacin-based naming, no stated concentration
Who it's for
Fits buyers looking for a multi-concern serum touching acne, wrinkles and general skin vitamins in one bottle. Not the choice for anyone who needs a serum with a stated active percentage or a full ingredient breakdown.
Strengths and trade-offs
Drawn from this product's published specifications.
- Addresses several concerns in one serum
- Available in fragrance free and fresh scent options
- 60 milliliter bottle size
- No active ingredient concentration listed
- UV protection claim is not a measured SPF
- Limited ingredient detail beyond addressed concerns
Performance notes
Niacinamide-type serums like this are generally used to support oil balance and even skin tone, and the listing ties this one to acne, wrinkles and vitamin delivery. The listed UV protection benefit refers to the serum addressing UV-related concerns, not a measured sun protection factor, so it does not replace sunscreen.
