Anti-Aging

Two things do most of the work here and everything else is support: sunscreen, and a retinoid. Sun exposure accounts for the large majority of visible skin aging, which means the cheapest anti-aging product you own is the SPF you actually wear every morning.

After that it is a question of how fast you want to go and how much irritation you will put up with. Retinal is the quick route. Peptides are the patient one — no purge, no peeling, and an option when vitamin A is off the table — but expect three months rather than three weeks. PDRN and collagen sit alongside both, working on repair and surface plumpness.

One rule worth keeping: never run acids and retinal on the same night. That is the mistake that sets people back weeks.
