Niacinamide for Eczema (Atopic Dermatitis)
A multitasker that calms redness, evens out skin tone, and helps oily skin balance out. One of the safest do-a-little-of-everything ingredients.
Why it works for Eczema (Atopic Dermatitis)
Strengthens your skin barrier so it holds water better and reacts less. Niacinamide is vitamin B3. At 2-5% it gets your skin to make more of its own ceramides and barrier proteins, and it calms the inflammation signals behind eczema. A trial (Draelos 2005, PMID:16209160) showed it improved the barrier and made skin less sensitive. It is gentle enough even for an eczema-damaged barrier, and it works well alongside ceramide moisturizers.
How Niacinamide works
Reduces transepidermal water loss, inhibits melanosome transfer, and dampens inflammatory cytokines.
