Performance Scores
SPF Level
Excellent
SPF Level
Product claims an SPF of 50, which is functionally supported by the inclusion of Octinoxate and Oxybenzone prominently in the active ingredients.
Broad Spectrum
Fair
Broad Spectrum
Avobenzone provides coverage for UVA I (peak 357 nm) while Oxybenzone covers the UVA II gap (peak 288 nm), creating continuous initial broad-spectrum coverage.
Sweat Resistance
Poor
Sweat Resistance
The ingredient list features water-soluble thickeners (Carbomer, Sodium Acrylates Copolymer) and humectants rather than dedicated water-proofing agents.
Photo Stability
Poor
Photo Stability
Established photobiology research confirms that unencapsulated Octinoxate and Avobenzone accelerate each other's degradation under UV exposure.
Visible Light
Poor
Visible Light
Absence of iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) or non-nano mineral filters in the ingredient list.
Irritation Risk
High Risk
Irritation Risk
Oxybenzone is cited by the North American Contact Dermatitis Group (NACDG) as the most frequent chemical UV filter to cause allergic contact dermatitis.
Pore Clogging
Low Risk
Pore Clogging
Dermatological comedogenicity scales consistently rate the primary vehicle components and chemical UV filters at 0/5, with no ingredients exceeding a 2/5 rating.
White Cast
Low Risk
White Cast
Chemical UV filters absorb rather than scatter or reflect UV radiation, leaving no opaque residue on the skin surface across all Fitzpatrick phototypes.
Ingredients Analysis
Active Filters
Octinoxate UVB
Studies indicate potential estrogenic and thyroid disrupting activity in animal models and human cell lines.
Avobenzone UVA I / UVA II
Rapidly degrades under UV exposure losing significant UVA protection capacity unless stabilized by other filters.
Oxybenzone UVB / UVA II
Clinical trials demonstrate that single applications lead to blood concentrations vastly exceeding safety thresholds and remaining detectable for weeks [1.1].
Key Inactive Ingredients
Triethanolamine pH Adjuster
May react with nitrosating agents in formulations to form nitrosamines which are potential carcinogens.
Lecithin Emollient
The Cosmetic Ingredient Review expert panel advises that lecithin should not be used in formulations containing nitrosating agents to prevent the formation of potentially carcinogenic N nitroso compounds [1.6].
Baikal Skullcap Root Extract Skin Conditioning
Although widely used for its soothing properties, there are emerging case reports of this extract acting as a novel botanical allergen and causing allergic contact dermatitis [1.1].
Aloe Vera Skin Conditioning
Unpurified aloe extracts may contain anthraquinones like aloin which are restricted to below 50 parts per million in cosmetics to prevent phototoxicity and skin irritation [1.2].
Polysorbate 20 Surfactant
As an ethoxylated ingredient, it may contain trace amounts of 1,4 dioxane and ethylene oxide, which are potential carcinogens linked to the manufacturing process.
Phenoxyethanol Preservative
Generally well tolerated but can cause contact dermatitis or skin irritation in rare cases, particularly in sensitive individuals.
