Hydroxycinnamic acid antioxidant that stabilizes the redox state of vitamins C and E in solution, extending their UV-photoprotective lifespan.
Why we tier this moderate
9 cited papers across 5 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.
