Topical Niacinamide
The all-rounder. Reduces redness, smooths texture, fades pigmentation, supports skin barrier, and pairs with nearly everything. Boring in the best way.
Strong for skin barrier function, reduction in transepidermal water loss, hyperpigmentation reduction (4% effective for melasma), and rosacea redness. Modest for acne. Effects: 4–12 weeks.
Topical niacinamide (vitamin B3) is one of the most well-tolerated and broadly useful skincare actives. It improves skin barrier function (ceramide production), reduces erythema and rosacea symptoms, modestly fades hyperpigmentation, calms acne inflammation, and reduces sebum production. The 4–10% range covers most clinical effects. Pairs comfortably with retinoids (calms irritation), vitamin C (the old incompatibility myth has been debunked), and pretty much every other active. A reasonable starting active for anyone new to skincare.
