What the gurus are saying

The fragrance is strong enough that some gurus find it intolerable, though others praise how noticeably it brightens and softens skin. Those sensitive to scent or already irritated by niacinamide may want to patch-test first; the high alcohol content amplifies the fragrance and can cause pilling when layered with sunscreen. The creamy texture makes the dropper application a bit messy, and at forty dollars for one ounce, the price is steep for what it delivers.

"The La Roche-Posay Pure Niacinamide Serum 10% is formulated for this purpose. If you were using your hyaluronic acid and you had some dry skin, you'd want to use this serum. The key is you don't want to just use one serum; you can combine those two serums with different ingredients to get more of a result. Niacinamide can help with things like pigmentation, so if you've got mild pigmentation and some dryness within the skin, you're going to choose hyaluronic acid and niacinamide."

"You really only need max 5%. 10% is kind of overboard and if anything can be more irritating. [...] The fragrance in their serums is so strong."

SKINCARE FAVES & FAILS *MARCH 2023* @DrDrayzday

"But the fragrance on this serum is so headache inducing I could not tolerate it whatsoever. [...] I don't like fragrance in skincare because [...] it's a common allergen, it can be irritating, and [...] this isn't even a pleasant scent, it's a very cheap perfume smell. I think the low molecular weight alcohol in the formula is what's driving that strong, long-lasting fragrance."

*NEW* LA ROCHE POSAY NIACINAMIDE 10 SERUM REVIEW 🤔 @DrDrayzday

"If you already find niacinamide irritating, this is at a higher percentage so that could be an issue, and the dropper is a bit messy since the product is almost more of a lotion consistency. It is forty dollars for one ounce. Do I think this is a good or bad product? I do not like these dichotomies."
