Question 319 of 433
What actually works for skin at home?

The short answer
Sunscreen every morning and a prescription retinoid at night. Everything else is a distant third.
Tretinoin is the only cream approved for sun-damaged skin, with decades of trials showing smoother texture and new collagen. It costs little as a generic. It irritates at first, makes skin sun-sensitive, and must not be used in pregnancy.
“Exosome” serums and facials are sold as cosmetics; no exosome product is FDA approved for anything, and the studies are small and paid for by the makers. Machine facials that cleanse and hydrate feel pleasant and last a few days. A rapamycin cream showed interesting changes in one small study and is far from proven.
