Peptides have made their presence undeniably known in the skincare and cosmeceutical industry. Many manufacturers have integrated these molecules into their creams, lotions, acclaiming anti-aging benefits. But just what are these molecules and can they actually have a positive effect on the skin?
To learn more about peptides, we must first explore skin physiology and skin chemistry. Each peptide is a part of a process in the body dealing with amino acids. They are shorter chains of amino acids. Amino acids are little blocks that join together. Most of the human body is made up of either protein or water.
Most of your vital organs are made of protein including skin, hair, and nails. Some peptides are used to generate or regenerate skin cells. According to research studies, there are some cosmetic peptides that help to reduce deep wrinkles and lines that are around your forehead. Sites like Peptide Sciences offer the US made research peptides for sale.
A dipeptide is two peptides joined together, a tripeptide is a group of three joined together. These are large molecules that are unable to penetrate the skin unless they are attached to a lipid-based molecule. Each peptide is essentially a fragment which stimulates the cell to do a specific job within the body. Their role is essential in the makeup of the human body.
So if you look at the composition of a cell, every cell has its own receptors. They have to be specific and match the corresponding cell receptors to activate the nucleus of those specific cells. If you do not have the right kind of peptide, it will do nothing. The receptor and the peptide have to match, so this is a very complex area for skincare.
More peptides in greater quantity do not mean a better product. Many manufacturers will try to add more to their skincare products. However, peptides can denature very quickly and the skin constantly renews itself. When applied to the skin, these products will lose efficacy and will not work overtime. When they do work, products with these ingredients typically work best in conjunction with Vitamin C.
There is preliminary scientific evidence that providing cells with peptides can potentially enhance collagen and elastin in the skin. In general, they are humectants that help the skin to retain more water. In theory, the humectant properties cause pores to become less noticeable, and skin to be plumped up. Theoretically, peptides convince the skin to produce more collagen and plump up the skin. It is important to note that collagen reduces 1% per year after the age of 30. This decline in collagen results in sagging skin, thinness around the temples, and fine lines.
Four Different Peptide Groups:
Carriers: Deliver trace collagen to the skin to boost collagen
Enzyme-inhibitor: Works to slow down the skin’s natural breakdown of collagen
Signals: Send messages out to make more collagen
Neurotransmitters: Works similarly to the neurotoxin Botox. Blocks the release of chemicals that cause muscle contractions and expression lines
Copper peptides have also become a new topic of interest in the beauty and skincare industry. Lotions and serums containing copper peptides claim to have significant anti-aging properties for the skin.
What Are Copper Peptides?
Naturally-occurring tripeptide used to combat hyperpigmentation and other skin issues. Its natural antioxidant properties are believed to stimulate healthy collagen production. They are believed to have a skin-restoring ingredient, causing skin improvement including increased firmness, smoothness, and a noticeable reduction of fine lines and wrinkles. According to scientific claims, they work by promoting collagen, and elastin, both crucial to the skin for optimal cell turnover rates.
Currently, there has been very little scientific evidence conducted on humans to back some of these claims.
