For your skin
A high-efficiency UVB and short-UVA filter used in modern Korean and European sunscreens. It supports high protection with less filter weight, which can help a formula feel lighter.

A highly photostable oil-soluble triazine filter with strong UVB and short-wave UVA absorption. It is used at relatively low concentrations alongside long-wave UVA filters to complete broad-spectrum coverage.
Why we tier this moderate
3 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.
