Nyob rau tib lub sijhawm, retinol tuaj yeem khi rau retinol binding protein (RBP) ntawm daim tawv nqaij thiab nkag mus rau cov hlwb los ntawm RBP receptors los tsim retinoic acid. Retinoic acid nkag mus rau hauv lub nucleus, ua ke nrog cov receptors cuam tshuam (RXR, RAR) los tsim ntau yam dimers, thiab ua ke nrog cov ntsiab lus retinoic acid teb raws li kev pab ntawm activators (xws li histone acetyltransferase). Los ntawm kev tswj hwm thiab tswj kev ua kom thiab kev qhia ntawm tus xa xov RNA hauv lub hauv paus, retinoic acid tswj kev faib cell thiab sib txawv thiab txhawb nqa keratinocyte proliferation. Nws tuaj yeem txhawb cov metabolism ntawm keratinocytes nyob rau hauv lub epidermis, txo cov degradation ntawm collagen nyob rau hauv lub dermis, thiab txhawb fibroblasts los tsim collagen ntau thiab hyaluronic acid.
