What Are Peptides?
Peptides are the mini-proteins, the short chains of amino acids typically comprising 2-50 amino acids that help regulate cell division and gene expression. They’re also a big part of our repair kit for every tissue and organ in our body. For example, they’re essential for healing, bone and muscle regeneration, sleep regulation, and weight loss. The human body naturally produces more than 7,000 known peptide types, which are used in a wide variety of the body’s systems.
Their biological role as molecules is to signal to other cells in the body how to function and metabolize. While peptides are natural, they can also be produced artiﬁcially outside the body for healing and repair. Unlike chemical drugs, peptides preserve the body’s natural feedback loops and restore our natural balanced state.
In skin care, peptides are best known for stimulating skin repair and supporting pro-aging efforts.
And they don’t have the irritating effects that more potent skin care ingredients, like retinoids, can have. Instead, peptides generally work by telling other cells to perform tasks like increasing collagen or elastin production. This is essential because the body’s production of collagen and elastin decline after age 20. Peptides also support a healthy skin barrier and promote the healing of wounds.
