Niacinamide + Peptides
Niacinamide + Peptides — a supportive, barrier-friendly pairing that combines vitamin B3 with short chains of amino acids used as signaling ingredients in skincare. Niacinamide helps reinforce the skin barrier and manage the look of tone and texture, while peptides are included to support the appearance of firmness and smoothness. The two are compatible and often appear together in the same formulas.
Key points
- Peptides are short amino-acid sequences used in cosmetics to support the look of firmness, hydration, and resilience.
- Niacinamide pairs well with peptides because both are non-exfoliating and unlikely to cause irritation.
- This combination is often marketed toward anti-aging or barrier-support routines rather than active exfoliation.
- Both ingredients function well at skin-friendly pH levels, so no special layering order is required.
- The duo is generally suitable for most skin types, including dry and sensitive skin.
