I work with a few different skincare lines and one of them has recently launched a new anti aging product loaded with different types of peptides. Peptides do quite the array of repairing, inspiring me to break it down a little. Keep in mind, there are many many types of peptides, these are just a few.
The main components of aging in the skin:
A.G.E(Advanced Glycation End-product)-When collgen protein and sugars found naturally in the skin link together its called glycation. This process causes loss of elasticity in the skin.
M.M.P's- mmp's are enzymes naturally occurring in the skin. When your young they are balanced with the amount of collagen and elastin in the skin, but as you age you produce collagen and elastin at a slower rate, resulting in mmp's breaking down too much collagen and elastin.
R.O.S.(Reactive Oxygen Species)- are a byproduct of oxygen in the skin. Also known as free radical damage) (Free radical damage is treated with powerful anti oxidants, not peptides, however ROS's are a major contributor to signs of aging, and should not be skipped)
Addressing the problem with Peptides:
AGE's- Argenine/lysine polypeptide- These peptides act as a sugar trap so sugars cannot cross link with collagen causing glycation.
MMP's-Palmitoyl Tripeptide-5 stimulates collagen synthesis, overrides MMP's. This peptide is essential for TGF(tissue growth factor).
These peptides will be labelled on skincare packaging so read your ingredients!
