The Top 5 Skin Care Ingredients You Need to Know
What it is: Peptides are segments of active proteins that communicate with cells and instruct them to behave in certain ways. In the skin, peptides may signal elastin production (elastin helps skin “bounce back”) or prompt skin to heal itself after a wound.
What it does: The peptides used in anti-aging products enter skin cells and instruct them to do certain things such as (surprise, surprise) produce collagen, alleviate redness or signal muscles to relax, thereby minimizing wrinkles. One common peptide found in skincare products is ‘palmitoyl pentapeptide’ which has been shown effective in fighting wrinkles. There are other peptides that don’t directly stimulate your skin to do anything, but because they are so small can penetrate deep into the layers and act as a delivery mechanism for other ingredients. Copper peptides, for example, bring molecules of copper deep into the skin where it can improve wound healing from the inside out.
