Performance Scores

SPF Level

Fair

Label claims SPF 30, corroborated by multiple high-efficacy UVB-absorbing filters positioned prominently in the ingredient list.

Broad Spectrum

Excellent

Bemotrizinol (Tinosorb S) and Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) provide continuous, highly effective absorption across the critical 315-400 nm UVA range.

Sweat Resistance

Poor

The ingredient list contains only water-soluble components and standard emulsifiers (e.g., Macrogol Cetostearyl Ether) without dedicated water-proofing agents.

Photo Stability

Excellent

Cosmetic science literature confirms that Bemotrizinol (Tinosorb S) is inherently photostable and acts as an effective stabilizer for less stable filters like Octinoxate.

Visible Light

Poor

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

Irritation Risk

Low Risk

Modern UV filters like Bemotrizinol and DHHB show exceptionally low rates of irritant and allergic contact dermatitis in clinical patch testing.

Pore Clogging

Low Risk

Dermatological reference scales evaluate Ceteareth-20 as mildly comedogenic (2/5) on its own, completely avoiding the severe 4/5 pore-clogging synergism that only occurs when it is co-formulated with cetearyl alcohol.

White Cast

Medium Risk

Moderate concentrations of un-tinted titanium dioxide predictably scatter visible light, causing an ashy residue on Fitzpatrick IV-VI skin (J Am Acad Dermatol).
