Peptides, a type of short-chain amino acids, are one of the most effective innovations in professional skincare. Known as the building blocks of protein, peptide supplements have been used by bodybuilders and athletes for decades to increase strength and help repair muscle. Recent studies have shown that using peptides in your skincare routine can provide some of the best anti-aging effects. Let’s take a look at the science behind these amino acids and how you can use them to achieve plumper, healthier skin!

 

How We Age

Collagen is a protein made up of long-chain amino acids— it works below the top layers of our skin to give it structure and elasticity. Thanks to collagen, our skin looks youthful, smooth and firm. But as we age, our ability to create more collagen slows and our existing collagen begins to break down.

When collagen breaks down, the top layers of the skin lose their underlying support, causing wrinkles, fine lines, sagging, and uneven texture. Certain environmental factors and lifestyle choices such as UV exposure and smoking can also make our collagen break down faster.

 

How Peptides Work

When collagen within the skin starts to deteriorate, it naturally releases peptides. These peptides signal to the skin that it has been injured, and trigger the body’s repair response to create new collagen and skin cells. When applied topically, peptides send that same message to your cells to produce more collagen. In a sense, topical peptides trick your skin into repairing itself even if it hasn’t experienced any injury or collagen loss.

There are hundreds of different kinds of peptides with their own unique skin rejuvenating properties. Certain peptides can help lift hyperpigmentation, while others have anti-inflammatory skincare benefits and can help restore hydration to the skin. One product can contain several peptides so be sure to look for a combo that targets your skin’s unique needs.

 

What to look for in a peptide

Incorporating peptides into your routine can be one of the best anti-aging skincare treatment for your skin as long as the peptides are delivered in the right format. Peptides work best when they are able to penetrate the skin barrier; instead of a thick cream that doesn’t fully absorb, opt for a lightweight peptide anti-aging serum that really sinks in. Peptides need to be combined with other active ingredients to help them absorb into the skin; look for an anti-aging serum that contains other actives like antioxidants or hydrating acids.

Our PSC PEPTIDE SERUM is rich in Rh-Oligopeptide-1, a powerful peptide that stimulates collagen production and promotes skin repair. It also uses natural plant stem cells to speed cellular turnover and antioxidant-rich gooseberry extract to protect the skin from free radical damage. To tackle the delicate area under the eyes, our FIRMING EYE COMPLEX uses tripeptide-1 and palmitoyl tetrapeptide-7, a peptide blend that can reduce fine lines and wrinkles while helping firm the skin. It also contains chrysin, a botanical skin conditioner that helps reduce the look of under-eye darkness and inflammation.

To get even better results, combine the serum with our cleansers, peels, microneedling and dermaplaning tools to drive active anti-aging ingredients deeper into the skin. After all, our skincare line is based on the breakthrough technique of combining or “stacking” treatments for a healthier, brighter, happier skin.
