Elevated MMPs after sun exposure

Could be why my skin gets SAGGY and easily damaged after sun exposure. I don't really get burns or redness, just a loss of elasticity.

"UV radiation increases the expression of matrix metalloproteinases (MMPs) in human skin. MMPs are responsible for degrading the extracellular matrix (ECM) proteins such as collagen, fibronectin, elastin, and proteoglycans, contributing to photoaging"
