Performance Scores

SPF Level

Excellent

Label claims SPF 50+, which is corroborated by the presence of multiple broad-spectrum and UVB filters positioned prominently in the active ingredients.

Broad Spectrum

Excellent

The inclusion of Mexoryl 400 specifically targets the ultra-long UVA I range (peaking at 385 nm), providing exceptional depth of coverage where most sunscreens fail.

Sweat Resistance

Poor

The presence of C12-22 Alkyl Acrylate/Hydroxyethylacrylate Copolymer provides functional water-resistant infrastructure, though unverified by stated testing claims.

Photo Stability

Excellent

Cosmetic science literature confirms that Bemotrizinol (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) effectively acts as a triplet-state quencher to prevent Avobenzone's photodegradation.

Visible Light

Poor

The ingredient list contains zero iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) or non-nano pigmentary minerals.

Irritation Risk

High Risk

Dermatological literature extensively documents that high concentrations of short-chain volatile alcohols significantly increase transepidermal water loss and irritation potential.

Pore Clogging

Low Risk

Clinical comedogenicity scales rate the primary vehicle ingredients (water, denatured alcohol, diisopropyl sebacate) at 0/5, with only tocopherol and triethanolamine carrying a low 2/5 rating at the bottom of the ingredient list.

White Cast

Low Risk

Organic filters such as Bemotrizinol, Avobenzone, and Mexoryl 400 operate by absorbing rather than reflecting visible light, preventing ashiness on Fitzpatrick IV-VI skin.


Ingredients Analysis

Active Filters

Octisalate ChemicalUVB

Clinical trials demonstrate systemic absorption into the bloodstream exceeding the FDA threshold requiring further safety testing.

Bemotrizinol ChemicalBroad Spectrum UV

Identified in recent dermatological literature as a rare but emerging cause of allergic contact dermatitis.

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.

Avobenzone ChemicalUVA I / UVA II

Rapidly degrades under UV exposure losing significant UVA protection capacity unless stabilized by other filters.

Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate ChemicalUVA I

Emerging case reports document rare instances of severe allergic contact dermatitis following topical application [1.1].

Diethylamino Hydroxybenzoyl Hexyl Benzoate ChemicalUVA II / UVA I
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

Ecamsule ChemicalUVA II / UVA I
