po ou se yon konpozisyon konplèks nan twa diferan kalite selil (kouch nan anwo nèt nan yo aktyèlman te mouri), likid divès kalite (ki gen ladan grès ak sebase, yon lwil oliv natirèlman pwodwi) ak lòt konpozan konjonktif (e.g., kolagen an ak elastin). domaj po a se pi souvan rezilta a nan oxidation- "radikal gratis" (elektwon san yo pa yon "lakay" atomik) ki kraze lyezon yo molekilè nan lòt konpoze. Sa a pann molekilè kapab afekte nenpòt matris eleman yon sèl po, ak rezilta yo varye. Pou egzanp:

Your skin is a complex composition of three different kinds of cells (the uppermost layer of them actually being dead), various fluids (including fat and sebum, a naturally produced oil) and other connective components (e.g., collagen and elastin). Skin damage is most commonly the result of oxidation—“free radicals” (electrons without an atomic “home”) that break the molecular bonds of other compounds. This molecular breakdown can affect any one skin matrix component, and the results vary. For instance:
