Peptides

What is it

What are Peptides?

Peptides are short chains of amino acids - the building blocks of proteins. In the skin, specific peptides act as signaling molecules, communicating with skin cells to trigger biological processes like collagen synthesis, elastin production, and barrier repair. Different peptide types accomplish different goals: some stimulate collagen and fibronectin synthesis, others relax the muscle contractions that lead to expression lines, and others reinforce the dermal-epidermal junction to improve structural integrity.

Benefits

What do Peptides do for your skin?

Peptides are highly targeted in their action - a long-game ingredient that rewards daily, consistent use. Key actions include:

  • Stimulates collagen and elastin synthesis for firmer, more resilient skin
  • Reduces the appearance of expression lines through neuromodulator-like action
  • Supports the structural integrity of the dermis and dermal-epidermal junction
  • Improves firmness and texture in delicate areas like the neck and eye area
  • Helps reverse the appearance of sun damage, brown spots, and textural irregularities

How to use

How do Peptides fit your routine?

Peptides are stable, gentle, and compatible with all actives - they can be used morning and evening without sequencing concerns. Most commonly found in serums, moisturizers, and targeted treatments. Consistent daily use over 8-12 weeks yields the most visible results.
