System Verdict
Technically excellent UV filters in a cosmetically elegant base, but witch hazel keeps this from being a universal no‑brainer. Efficacy is high because it uses a modern, photostable, broad‑spectrum filter quartet (Ethylhexyl Triazone, Drometrizole Trisiloxane, Diethylamino Hydroxybenzoyl Hexyl Benzoate, Terephthalylidene Dicamphor Sulfonic Acid) at the top of the INCI, combined with humectants and niacinamide for supporting hydration and pigmentation control, in a lightweight, non‑whitening emulsion well‑suited to daily wear. The score is dragged down slightly by the inclusion of witch hazel leaf water (potentially irritating for very sensitive or barrier‑impaired skin) and the lack of additional strong barrier lipids or multiple molecular‑weight humectants that would push it into a truly treatment‑level sunscreen.
