Performance Scores

SPF Level

Excellent

Label claims SPF 50+, which is strongly corroborated by the prominent presence of UVB filters including Octinoxate, Iscotrizinol, and Titanium Dioxide.

Broad Spectrum

Excellent

Bemotrizinol (peak 345 nm) and Diethylamino Hydroxybenzoyl Hexyl Benzoate (peak 354 nm) provide highly stable, overlapping protection deep into the critical UVA I range (340-400 nm).

Sweat Resistance

Poor

Ingredients such as Dimethicone and Divinyldimethicone/Dimethicone/Phenylsilsesquioxane Crosspolymer function as water-resistant film formers, but their durability remains unverified by standardized testing.

Photo Stability

Excellent

Peer-reviewed photobiology research confirms that Bemotrizinol (Tinosorb S) effectively quenches the excited state of older filters like Octinoxate, preventing their UV-induced degradation.

Visible Light

Poor

The ingredient list contains zero iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) and no non-nano physical blockers designated for visible light attenuation.

Irritation Risk

Low Risk

Silicones and large-molecule UV filters (Bemotrizinol, DHHB) are widely documented in dermatological literature as non-irritating to intact skin.

Pore Clogging

Low Risk

Clinical comedogenicity scales rate the primary vehicle ingredients (cyclopentasiloxane, dimethicone crosspolymers) and active UV filters at 0/5, with minor ingredients like octyldodecanol and talc rated only 1/5.

White Cast

Medium Risk

Moderate concentrations of un-tinted titanium dioxide without documented nano-technology consistently produce visible reflectance on Fitzpatrick IV-VI skin.
