FAQ
What is a peptide?
Peptides are short chains of amino acids “such as glycine, arginine, histidine, etc.,” Dr. Kim says. “Designed to strengthen and replenish amino acids, which are the building blocks of collagen production.” Amino acids may be recognized as building blocks of proteins, but peptides tend to have shorter chains than proteins. Also, compared to topical collagen, peptides have a smaller particle size, which allows them to penetrate deeper into the skin’s surface level. According to Dr. Kim, these are great for reducing fine lines and keeping your skin firmer.
What effect do peptides have on the skin?
As Dr. Hartman previously explained, the quantity and quality of our bodies’ natural collagen production decreases over time. As a result, wrinkles begin to form and the skin begins to sag, but the peptide chains mimic the structure of amino acids and alleviate these concerns. Mature skin in particular can benefit from peptides that improve skin firmness.
However, not all peptides are created equal. The most common types of peptides consist of signal peptides, carrier peptides, enzyme-inhibiting peptides, and neurotransmitter-inhibiting peptides, all of which have specific functions. (Also note that research institutes and brands can and often do trademark their own peptide conjugates.) For example, copper peptides are: carrier peptide-They activate wound healing and deliver copper to the skin, which in turn stimulates collagen production. While the actual product packaging often has “peptide” written front and center, ingredient lists often categorize peptides by the number of amino acids they contain, such as dipeptides (2), tripeptides (3), and hexapeptides (6). It is not uncommon for multiple peptides to be linked together to maximize the effect of increasing collagen.
Although peptides rarely cause skin sensitivity or irritation, you should still be careful about the formulation of your serum. “If someone has it, [negative] “The reaction is most likely due to the preservatives, other chemicals, or essential oils in the formulation, rather than the peptide,” Dr. Kim says.
