Peptides + Niacinamide

Peptides + Niacinamide — a combination of peptides, short amino acid chains that signal skin-supporting functions, with niacinamide, a form of vitamin B3 that strengthens the skin barrier and helps regulate oil and tone. Together they form a gentle, supportive routine aimed at resilience, hydration, and a smoother appearance.

Key points

• Niacinamide supports the skin barrier, helps manage oil, and can improve the look of pores and uneven tone.
• Peptides contribute signaling activity that may support firmness and barrier repair.
• Both are well tolerated and rarely cause the irritation linked to stronger actives.
• The pair suits most skin types, including sensitive and combination skin.
• They layer easily with hydrators like hyaluronic acid for added comfort.
• Consistent use supports gradual improvements in texture and barrier strength.
