A photostable oil-soluble filter focused on long-wave UVA, including the wavelengths that penetrate most deeply and contribute to photoaging and persistent pigmentation. It converts absorbed ultraviolet energy into heat.
Why we tier this moderate
2 cited papers across 2 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.
