Metalloproteinases, also known as metalloprotease, matrixons or MMP is simply put, a degradation to collagen and elastin fibers, the main framework of skin cells. The process of this aging of the skin is explained in the name, it is a protein enzyme that is involved with a metal. Our bodies hold 23 MMP enzymes that help break down, one being MMP-1 or collagenase, which breaks down collagen. We aquire the bad Metalloproteinases with unprotected sun exposure, and it is also found in sebum, a secretion in the sweat gland. (3)
Retinol, Ferulic acid, Vitamin C, Vitamin E, Kelp Extract, Phloretin, and Omega 3 acid ( eicosapentaenoic acid ), and green tea have shown to inhibit and correct the effects of MMP-1. Tissue inhibitors of metalloproteinases or TIMPs such as these are great for anti aging products.
One part of wound healing that doctors will look at is the level of MMP-1 to the level of TIMPs to figure out the healing process of a wound. Patients with a high level of MMP-1 can have their wounds heal slowly or stop healing altogether. Fibroblasts is a tissue that secretes collagen proteins that are the framework of connective tissue.(1) Retinol is a key ingredient in resurrecting and maintaining fibroblasts in the skin to function in creating collagen. (2) Because of this, Fibroblasts are a major source of TIMPs
