Peptides for Skin: What Are the Benefits?

Peptides are naturally occurring amino acids the skin produces on its own. However, you can also introduce them through high-end skincare products. In doing so, you can support your skin barrier and improve your complexion from a cellular level.

Enhanced Protection From Sun Damage and Irritants

Peptides are unique in their ability to penetrate and fortify the skin barrier. Some research suggests that this characteristic may offer protection against sun damage, which can not only increase the risk of skin cancer but also lead to premature aging, wrinkling, and discoloration. Of course, peptides don’t replace sunscreen.

A boosted skin barrier helps protect your skin from a wide range of pollutants, such as smoke and smog. This means fewer breakouts, less irritation, and greater skin health.

Reduced Fine Lines and Wrinkles

Another major benefit of peptides is the fact they promote collagen and elastin production. Anyone looking to smooth their complexion and target signs of aging can turn to peptides as a natural, effective treatment.

Soothe Inflammation

As anti-inflammatory agents, peptides can reduce redness and irritation, leading to a more refreshed appearance.

What Are the Best Types of Peptides for Skincare?

We use three specific peptides in our formulations:

  • Acetyl Hexapeptide-8: A synthetic peptide optimized for enhancing collagen and reducing the appearance of wrinkles.
  • Palmitoyl Pentapeptide-4: A combination of fatty and amino acids, clinically studied and designed to work as well as retinol with less irritation.
  • Palmitoyl Tripeptide-3 (Matrixyl™): Designed to mimic the skin’s natural barrier, this peptide simulates the tissue growth factor (TGF) to enhance collagen production.
