What are Peptides In Skincare?

Peptides are short chains of amino acids, the building blocks of proteins in the skin, produced by the body. Collagen is made up of amino acids and contains three polypeptide chains, making peptides a great addition to your routine.

As we age, our skin’s needs change and these changes show on our skin. It is why we start to notice expression lines, a duller complexion, and uneven textures. And skin aging can accelerate due to environmental stressors like pollution, dirt, makeup, and weather.

To assist our skin in repairing and rebuilding, ingredients such as peptides help slow aging by boosting collagen and elastin production.

The result? These active ingredients help reduce fine lines and wrinkles, repair the skin barrier, and give you firmer and younger-looking skin!
