A clinically rigorous retinol serum built on a surgeon's three-decade obsession with vitamin A, delivered through a progressive step-up system that most consumer brands cannot match. The formulation is thoughtful if not modern — colostrum and DMDM hydantoin are polarizing choices — but the results-driven philosophy and vitamin A-C-E synergy make this a serious tool for aging and photodamaged skin.
