(13) Niacin Serum 20%

A precision serum that elevates skin to its best version. From the very first touch, Niacin Serum 20% by Prof. Dr. Steinkraus melts into the skin to perfect texture, even out tone and strengthen the skin barrier. Its high concentration of niacinamide, backed by botanical ferments and a smart moisturizing system, delivers an elegant transformation: calmer skin, visibly refined pores and a controlled, healthy-looking glow.

Key benefits

• Tone evenness: pigment-balancing action that helps reduce spots and smooth out tonal irregularities.
• Strengthened barrier: supports regenerative processes and boosts epidermal lipids (ceramides) for more resilient skin.
• Pores and texture: sebum-regulating, pore-refining effect that perfects the skin's surface without drying it out.
• Antioxidant comfort: rye ferments and heather extract provide protection and calm against external aggressors.
• Smart hydration: hyaluronic acid and glycerin ensure flexibility and an immediate feeling of plumpness.

Science and active ingredients

• Niacinamide (20%): multi-active ingredient that regulates melanin transfer, improves barrier function, refines pores and balances sebum.
• Botanical ferments (Secale cereale & Calluna vulgaris): support physiological renewal, the skin's ecosystem and antioxidant defense.
• Hyaluronic acid (Sodium Hyaluronate): high-performance hydration with a more elastic, comfortable skin feel.
• Copper (Copper Gluconate): cofactor that supports collagen synthesis and tissue repair processes.
• Moisturizing and texturizing complex: glycerin, pentylene glycol and natural gums that optimize absorption and sensoriality.

Feel and results

Light, fast-absorbing texture with a neat finish. With consistent use, skin reveals a more even tone, visibly reduced pores and a strengthened barrier that translates into lasting comfort and refined radiance.

How to use

• Application: apply at night on clean, dry skin; let it absorb for 2–3 minutes before your treatment cream.
• Frequency: daily nighttime use; if preferred, it can also be used in the morning (always with sun protection).
• Synergies: pairs excellently with hyaluronic acid serums and with vitamins A and C in alternating routines.
