Molecular messenger of sight: Scientists investigate protein structure RBP3's role in vision - MSNRBP3 plays a key role in delivering all-trans-retinol (at-ROL) from photoreceptors to the retinal pigment epithelium, where it is converted into 11-cis-retinal (11c-RAL), a key molecule for vision ...
Retinol is part of a group of vitamin-A-derived chemical compounds called retinoids. Retinoids boost the production of collagen , a protein that can improve the look of wrinkles.
Retinol also stimulates the production of collagen (a key protein that creates a scaffolding that keeps skin firm and elastic) and fibroblasts (cells that produce collagen and support skin structure).

Most dermatologists estimate that retinol is roughly 10 times less potent than tretinoin, meaning that when retinol undergoes the conversion process, only about 10 percent of it becomes retinoic acid.
