Niacinamide helps strengthen the skin's lipid barrier, which is crucial for maintaining moisture and protecting against environmental aggressors. By supporting the skin's natural content of ceramides and fatty acids, niacinamide helps to prevent transepidermal water loss, keeping the skin hydrated and resilient.
When used as part of a daily skincare routine, niacinamide may help calm the skin, reduce transepidermal water loss (TEWL), and increase hydration in the skin's uppermost layer. This makes niacinamide a beneficial skincare ingredient for those looking to promote hydrated, smooth, and even-toned skin.

In fact, you can use niacinamide-containing topical products in the morning and night because it's generally a gentle ingredient.

Niacinamide regulates sebum production, unclogs pores and upholds the lipid barrier, among many other things. On the other hand, Vitamin C in your daily routine boosts Collagen production and averts free radicals for the dreamiest skin ever.

Niacinamide is used to treat hyperpigmentation and reduce fine lines and wrinkles, while alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are chemical exfoliants. To understand why niacinamide shouldn't be mixed with AHAs and BHAs, you need to consider pH.
