Niacinamide Niacinamide
Niacinamide (vitamin B3) is a versatile active ingredient, one of the best-studied in dermatology — with documented efficacy across many categories of skin concerns. It works in multiple directions: it strengthens the hydrolipid barrier by stimulating ceramide production, inhibits the transfer of melanin to keratinocytes (brightens hyperpigmentation), regulates sebum secretion, and reduces the appearance of pores. It has strong anti-inflammatory action, reducing redness, soothing rosacea, and calming skin reactivity. It suits all skin types and combines well with all other active ingredients (including AHA/BHA acids and retinol). The best results are observed at concentrations of 4-10% and with regular use for at least 8 weeks.
