For your skin
A workhorse antioxidant that defends your skin from daily oxidative damage. Pairs especially well with vitamin C, and it's in nearly every good moisturizer for a reason.

Vitamin E works through 3 pathwaysin skin. Here's what each looks like at the cellular level:
Donates a hydrogen to neutralize free radicals before they damage skin lipids.
Quenches UV-induced oxidative damage when applied topically, especially in combination with vitamin C.
Concentrates in sebum and the upper stratum corneum, stabilizing the lipid mortar between cells.
Why we tier this moderate
6 cited papers across 3 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
