Performance Scores
SPF Level
Excellent
SPF Level
Label claims SPF 50, which is corroborated by the prominent presence of multiple high-efficacy UVB filters with peak absorptions between 311 nm and 314 nm.
Broad Spectrum
Excellent
Broad Spectrum
The combination of DHHB, Bemotrizinol, and Bisoctrizole provides strong overlapping absorption peaks at 354 nm, 345 nm, and 360 nm, robustly covering the 315-400 nm range.
Sweat Resistance
Poor
Sweat Resistance
Film-forming polymers such as Sodium Polyacrylate and Polyacrylate Crosspolymer-6 are present, establishing a basic physical infrastructure without verified water-resistance testing.
Photo Stability
Excellent
Photo Stability
Dermatological literature demonstrates that Bemotrizinol (Tinosorb S) acts as an effective photostabilizer for other less stable UV filters by safely dissipating excited-state energy.
Visible Light
Poor
Visible Light
The ingredient list contains zero iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) or pigmentary minerals, resulting in no structural visible light protection.
Irritation Risk
Medium Risk
Irritation Risk
Decyl glucoside and propylene glycol are well-documented sensitizers (named Contact Allergens of the Year in 2017 and 2018, respectively), though they appear at lower concentrations here.
Pore Clogging
Low Risk
Pore Clogging
Dermatological reference databases and clinical assays rate the primary base ingredients, such as dicaprylyl carbonate and dibutyl adipate, at 0-1/5, while the emulsifier Steareth-21 carries a minor 2/5 rating.
White Cast
Low Risk
White Cast
Tinosorb M acts via both absorption and scattering of UV light due to its microfine particulate nature, causing mild reflectance.
Ingredients Analysis
Active Filters
Octinoxate UVB
Studies indicate potential estrogenic and thyroid disrupting activity in animal models and human cell lines.
Ethylhexyl Triazone UVB
Currently not approved by the United States FDA for use in sunscreens though it is widely approved in the EU and other global markets.
Bemotrizinol Broad Spectrum UV
Identified in recent dermatological literature as a rare but emerging cause of allergic contact dermatitis.
Key Inactive Ingredients
Steareth-21 Emulsifier
As an ethoxylated compound it may contain trace amounts of 1,4 dioxane and ethylene oxide which are probable carcinogens if not adequately purified during manufacturing [1.3.1].
Methyl Methacrylate Crosspolymer Sensory Modifier
Functions as a synthetic polymer microbead that is often classified as a microplastic, raising concerns about environmental persistence and marine pollution.
Decyl Glucoside Surfactant
Named Contact Allergen of the Year in 2017 due to increasing reports of allergic contact dermatitis, though it remains safe and mild for the vast majority of users.
Phenoxyethanol Preservative
Generally well tolerated but can cause contact dermatitis or skin irritation in rare cases, particularly in sensitive individuals.
Ethylhexylglycerin Preservative
Recognized as a rare but emerging cause of allergic contact dermatitis, particularly in leave-on cosmetic products.

Propylene Glycol Solvent
Recognized as a frequent cause of allergic contact dermatitis especially in individuals with eczema or compromised skin barriers.
