Peptides are short chains of amino acids (or protein fragments) that act in a similar way to a key and lock. They are keys that carry a specific message—to produce collagen, reduce pigmentation or renew cells—and they unlock receptor’s pathways to that activity in the skin.
Skin Benefits of Peptides
Soy rice peptides, which stimulate fibroblast proliferation and increase collagen and elastin synthesis, have been shown to reduce dark circles and puffiness around the eyes. Palmitoyl tetrapeptide-7 reduces inflammation caused by reduced fluid retention and swelling, resulting in increased firmness and tone of the eye area. Acetyl hexapeptode-8, on the other hand, reduces wrinkle depth and is very effective for lines around the corners of the eyes and the mouth area
Peptides are much safer than other harsh ingredients and deliver better results. They are like body builders for the skin. They allow it to become stronger and act in a healthier way. By applying certain topical peptides to your skin, you’re also nourishing it with a protein-rich diet that strengthens, nourishes, and realigns the building blocks of the skin, giving way to a stronger, healthier foundation.
Formulation Challenges
Formulating always starts efficacy and understanding of peptide’s therapeutic range. The choice of ingredients depends on the overall goals of the final product.
As peptides’ size increases, it also becomes more difficult for them to penetrate the skin. Very long peptides with desirable properties are simply impossible to deliver into the skin. Peptides are generally difficult to combine with many other ingredients because of their unique chemistry.
However, peptide-rich treatment serum every morning and every night under a moisturizer are strongly recommended. During the day, it should be paired with a sunscreen for the best results and protection. Adding a peptide-rich eye cream for increased radiance and anti-aging benefits is also encouraged.
