Ectoin Vs. Niacinamide - Which Is Right For You?
Both ectoin and niacinamide support the skin barrier - though they work differently to do so. Ectoin supports the skin barrier by binding moisture to the skin and creating a film on the skin that prevents water loss. Niacinamide helps to facilitate the production of ceramides and elastin, two critical parts of the skin barrier; it helps support the skin's natural shield.
