What Are Peptides in Skincare? (Types, Pairings, Results)

What are peptides in skincare?

Peptides are short chains of amino acids that “message” skin to do useful things like make more collagen, improve elasticity, or calm reactivity without the irritation of strong actives.

Which peptide types matter most?

Signal peptides nudge collagen/elastin. Carrier peptides deliver minerals to aid repair. Neurotransmitter-inspired peptides can soften expression lines. Many formulas blend types for a broader effect.

What benefits should I expect?

Smoother texture, better bounce, and improved fine lines with consistent use. Most users notice plumper feel in 2–4 weeks, with firmer look by 8–12 weeks.

How do I use peptides in a routine?

Apply after toner, before oils and creams. Use AM and PM for best compounding results. They’re gentle enough to pair with most actives daily.

Can peptides be layered with acids and vitamin C?

Yes. Keep peptides daily and cycle stronger actives. Example stack:
AM: Vitamin C → Peptides → SPF.
PM (alternate nights): Glycolic or Bakuchiol, plus Peptides.

Peptides vs retinoids/bakuchiol: which should I choose?

You don’t have to. Retinoids/bakuchiol address texture and renewal; peptides support firmness and repair. Pair them on alternate nights for results with minimal irritation.

Who are peptides best for?

All skin types, especially sensitive or barrier-compromised skin that struggles with frequent acids or retinoids. They’re also ideal as a daily “baseline” active.

Any safety notes?

Peptides are well-tolerated. Patch test new products for 24–48 hours, especially around eyes. If you’re nursing or pregnant, peptides are a friendly pick—confirm with your clinician.
