What are peptides in skincare?

Peptides naturally occur within our skin. A short chain of amino acids, peptides are called polypeptides when that chain gets longer. Peptides serve as the building blocks for proteins. For example, collagen (the most abundant protein in our bodies — and a critical one for healthy skin) consists of three polypeptide chains. 

Peptides are known as a powerful ingredient in skincare because they play a central role in anti-aging. Want to improve the look of your skin, making it appear firmer, smoother, and glowing with less texture and fine lines? Peptides just might be your new best friend. 

Peptides help keep skin healthy in a number of ways, including helping the body produce more collagen and elastin. Peptides can act like little signals for your skin, telling it to clear out old, damaged collagen and elastin and helping your body make more of these proteins. Other peptides can help support the skin’s process of producing hyaluronic acid (the naturally occurring substance that helps skin stay hydrated and looking fresh and plump), as well. 

There’s also evidence that some peptides have antioxidant properties that help protect the skin from future damage. Think of them as a shield for environmental stressors — like UV radiation and pollution — that can prematurely age the skin. 

When formulated correctly, peptides can have tremendous benefits for skin health and appearance. However, not all peptides are made equally. Many ALASTIN Skincare products feature a very special (and proprietary) blend of active peptides and botanicals called TriHex Technology®

In studies, TriHex Technology® has been shown to support the production of new, healthy collagen and elastin. TriHex Technology® include the peptides Tripeptide-1 and Hexapeptide-12 that support the removal of damaged, aged collagen and elastin which can clog up the production of new collagen and elastin. It also helps the body’s natural ability to rebuild new healthy collagen and elastin and continue to replenish these proteins to establish and maintain younger-looking skin. 

  • Reducing the appearance of fine lines and wrinkles. Collagen and elastin replenishment naturally helps reduce the appearance of fine lines and wrinkles. 
  • Restore volume and improve elasticity. As skin ages, it can look sunken (think your eyes and cheeks) and wane. Certain peptides help to correct this by helping skin to look firmer and smoother. 
  • Increasing hydration. Peptides can help attract and retain moisture in the skin by helping the skin to create more naturally occurring hyaluronic acid, thereby creating a more hydrated, plumper appearance. 
  • Improving skin barrier function. Peptides may help to strengthen the skin’s natural barrier, which can help protect it from environmental damage and premature skin aging.

Yes, certain peptides can help make skin look skin tighter. It all depends on the peptide and the formulation. The regeneration of elastin — one of the benefits of TriHex Technology® — will aid in tightening the look of skin. Plus, peptides found in ALASTIN products that target areas of the skin where laxity (aka sagginess) is a common problem help, too. You can find additional peptides that help tighten the look of skin in Restorative Neck Complex with TriHex Technology and TransFORM Body Treatment with TriHex Technology®

Here are some of the most powerful peptides and peptides blends for your skin—plus which products you can find them in.
