Sun damage is the biggest driver (and hopefully most people know that!) But these four are doing real damage quietly. Glycation is the most underrated, when glucose binds to collagen and elastin it forms advanced glycation end products that make the tissue stiff and brittle. That process is not reversible topically. Chronic elevated cortisol activates enzymes that degrade collagen, which is why people who've been through extended difficult periods often notice their skin looking different afterward. And the jaw line one is simple: your neck and chest get the same UV and none of your skincare. #longevity #skinaging #skincaretips #dermatologist
