Performance Scores

SPF Level

Excellent

Label claims SPF 50+, which is validated by the presence of Ethylhexyl Triazone (peak absorption at 314 nm) prominently positioned in the active ingredients alongside the SPF booster Butyloctyl Salicylate.

Broad Spectrum

Excellent

Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) provides robust UVA I coverage (peak 354 nm), while Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine and Drometrizole Trisiloxane offer continuous, overlapping absorption across UVA I and UVA II.

Sweat Resistance

Poor

Ingredients like Poly C10-30 Alkyl Acrylate, Polyether-1, and Acrylates/C10-30 Alkyl Acrylate Crosspolymer function as water-resistant film-formers, but without clinical testing claims (e.g., 40 or 80 minutes), resistance is assumed minimal.

Photo Stability

Excellent

Cosmetic science and photobiology literature confirms that DHHB, BEMPT, and Mexoryl XL/SX undergo rapid, non-destructive energy dissipation upon UV absorption, rendering them highly resistant to photodegradation.

Visible Light

Poor

Complete absence of iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) and pigmentary-grade non-white minerals in the ingredient list.

Irritation Risk

Low Risk

Clinical literature confirms that Tinosorb S, Uvinul A Plus, and Mexoryl derivatives have exceptionally low irritant and allergenic potential compared to legacy filters.

Pore Clogging

Low Risk

Dermatological reference scales rate the primary vehicle ingredients and UV filters at 0/5, while minor components like rice bran oil and glyceryl stearate typically score 1-2/5.

White Cast

Low Risk

Organic UV filters absorb rather than scatter visible light, eliminating the physical mechanism of white cast (Photodermatol Photoimmunol Photomed).


Ingredients Analysis

Active Filters

Ethylhexyl Triazone ChemicalUVB

Currently not approved by the United States FDA for use in sunscreens though it is widely approved in the EU and other global markets.

Drometrizole Trisiloxane ChemicalBroad Spectrum UV

Approved up to 15 percent in the EU and other regions but remains unapproved by the US FDA for over the counter sunscreens due to administrative delays

Terephthalidene Dicamphor Sulfonic Acid ChemicalBroad Spectrum UV

Clinical trials demonstrate systemic absorption into the bloodstream exceeding FDA safety thresholds which prompted requests for additional toxicological data [2.4].

Diethylamino Hydroxybenzoyl Hexyl Benzoate ChemicalUVA II / UVA I
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine ChemicalBroad Spectrum UV

Although widely tolerated and nonirritating for most users recent dermatological reports identify it as an emerging allergen capable of causing rare cases of allergic contact dermatitis [2.1]
