Performance Scores
SPF Level
Excellent
SPF Level
Formula utilizes four dedicated UVB filters (Homosalate, Octinoxate, Octisalate, Iscotrizinol) in top ingredient positions to ensure robust UVB attenuation.
Broad Spectrum
Fair
Broad Spectrum
Avobenzone provides primary UVA I coverage (peak 357 nm) and Bemotrizinol provides broad-spectrum overlap (peak 345 nm), but the system relies heavily on a photolabile primary filter.
Sweat Resistance
Poor
Sweat Resistance
The base relies on water-soluble Ethyl Alcohol and Triethylene Glycol, paired with Polysorbate 20 (a wash-off facilitating surfactant), with zero water-proofing agents present.
Photo Stability
Poor
Photo Stability
Photobiology research demonstrates that combining unstabilized Avobenzone with Octinoxate leads to rapid cleavage of both molecules under UV irradiation, drastically reducing protective efficacy.
Visible Light
Poor
Visible Light
Total absence of iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) and mineral filters (Zinc Oxide, Titanium Dioxide) in the ingredient list.
Irritation Risk
High Risk
Irritation Risk
High concentrations of short-chain volatile alcohols are well-documented to extract intercellular lipids, compromising the skin barrier and inducing erythema.
Pore Clogging
Low Risk
Pore Clogging
Dermatological reference scales rate the primary vehicle (ethyl alcohol) and all UV filters at 0/5, with triethanolamine historically rated at 2/5 in rabbit ear assays.
White Cast
Low Risk
White Cast
Organic filters like avobenzone and homosalate operate via molecular UV absorption rather than physical reflection, leaving no visible surface residue.
Ingredients Analysis
Active Filters
Homosalate UVB
Laboratory studies indicate homosalate may act as an endocrine disruptor by interfering with hormone systems [1.1].
Octinoxate UVB
Studies indicate potential estrogenic and thyroid disrupting activity in animal models and human cell lines.
Octisalate UVB
Clinical trials demonstrate systemic absorption into the bloodstream exceeding the FDA threshold requiring further safety testing.
Avobenzone UVA I / UVA II
Rapidly degrades under UV exposure losing significant UVA protection capacity unless stabilized by other filters.
Bemotrizinol Broad Spectrum UV
Identified in recent dermatological literature as a rare but emerging cause of allergic contact dermatitis.
Key Inactive Ingredients
Ethyl Alcohol Solvent
Can strip the natural lipid barrier of the skin and cause dryness or compromised barrier function especially when used at high concentrations.
Fragrance Fragrance

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.
Triethylene Glycol Solvent
Should not be used on damaged skin due to the risk of systemic toxicity and contact dermatitis as observed with similar PEG based ointments in burn patients [1.5].
BHT Antioxidant
Some animal studies suggest high oral doses may cause endocrine disruption, though regulatory bodies consider it safe at the low concentrations used in cosmetics.
Triethanolamine pH Adjuster
May react with nitrosating agents in formulations to form nitrosamines which are potential carcinogens.
