With all this talk of peptides in skin care, it can be perplexing to understand which ones can do what for you. All cosmeceutical peptides seem to signal the cells that synthesize collagen, called fibroblasts.Thus far, no “bad” peptide has been discovered, and the three listed here have reputably proven benefits. These particular peptides exhibit the noninflammatory, fibroblast feature along with the following cosmetic powers.
1. Acetyl Hexapeptide (aka Argireline)
This polypeptide is touted as the Botox -or Dysport- alternatives. It can also prolong the life of cosmetic toxin injections because acetyl hexapeptide has been proven to inhibit muscle contractions. This particular hexapeptide- also called argireline- smooths the skin’s surface as well as prevents wrinkles from forming, particularly due to repetitive muscle contractions. Expensive products containing argireline may be best applied solely on frown line areas, unless this ingredient is contained in a sunscreen product. IMAGE Skincare’s new Ultimate Solar Defense SPF 35 is the most reasonably priced sunscreen that contains acetyl hexapeptide as well as stem-cell technology.
2. Palmitoyl Pentapeptide
Products containing this peptide tend to be the most highly priced, but its benefits to aging skin are highly desirable. Research shows that this peptide (1) combats sagging, (2) thickens the skin (great for crepey areas), and (3) smooths wrinkles. These effects are listed according to the pentapeptide’s order of impact. Studies reveal that palmitoyl pentapeptide actually activates wound healing genes and simulates the human body’s regeneration process. What’s more is that there is no inflammatory response from the application of this potent ingredient. PCA SKIN’s Eye Excellence contains this particular peptide.
3. Palmitoyl Tripeptide
As with the aforementioned pentapeptide, this one does not produce any negative side effects. Applied twice a day, for six weeks, one can expect a 10 to 15% reduction in the appearance of wrinkles. This tripeptide also firms lax skin by means of collagen reinforcement. This underlying cushion of the skin is bolstered, making the overall look of the treated skin firmer and plumper. PCA SKIN’s Peptide Lip Therapy contains this plumping tripeptide.
