Niacinamide for Seborrheic 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 Seborrheic dermatitis

Calms redness and cuts back on the oil that feeds the yeast. It quiets the skin's inflammation signals and lowers oil output. In a study of 48 people with facial seborrheic dermatitis (Fabbrocini 2014), a 4 percent niacinamide cream cut the combined redness, scaling, and thickening score by 75 percent over 12 weeks, versus 35 percent for the plain cream.

How Niacinamide works

Reduces transepidermal water loss, inhibits melanosome transfer, and dampens inflammatory cytokines.
