Performance Scores
SPF Level
Excellent
SPF Level
Manufacturer label of SPF 50+ is verified by the presence of primary UVB filters (Octinoxate, Iscotrizinol, BEMT) occupying prominent positions in the ingredient list.
Broad Spectrum
Excellent
Broad Spectrum
DHHB (peak 354 nm) and BEMT (peak 345 nm) create an overlapping and continuous absorption profile from 315 nm up to 400 nm, fully justifying the PA++++ claim.
Sweat Resistance
Poor
Sweat Resistance
The presence of PEG-12 Dimethicone/PPG-20 Crosspolymer and Cetyl PEG/PPG-10/1 Dimethicone indicates a water-in-silicone emulsion infrastructure capable of baseline water resistance.
Photo Stability
Poor
Photo Stability
Recent photobiology studies demonstrate that Zinc Oxide can catalyze the rapid degradation of co-formulated small-molecule organic filters under UV irradiation, compromising long-term protection.
Visible Light
Poor
Visible Light
An ingredient list scan confirms the complete absence of iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) or pigmentary-grade non-nano minerals.
Irritation Risk
Medium Risk
Irritation Risk
Dermatological assessments classify dioctyl sodium sulfosuccinate as a cumulative irritant, and synthetic fragrance remains a top trigger for contact dermatitis.
Pore Clogging
High Risk
Pore Clogging
Dermatological comedogenicity scales, including standard rabbit ear and human clinical assays, routinely assign Sodium Chloride a 5/5 and Isostearic Acid a 4/5 for pore-clogging potential.
White Cast
Medium Risk
White Cast
Moderate concentrations of non-micronised or standard zinc oxide consistently leave visible white reflectance on Fitzpatrick IV-VI skin types.
Ingredients Analysis
Active Filters
Octinoxate UVB
Studies indicate potential estrogenic and thyroid disrupting activity in animal models and human cell lines.
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine Broad Spectrum UV
Although widely tolerated and nonirritating for most users recent dermatological reports identify it as an emerging allergen capable of causing rare cases of allergic contact dermatitis [2.1]
Key Inactive Ingredients
Cyclopentasiloxane Emollient
The European Union is restricting this ingredient to a maximum concentration of one tenth of a percent in leave on cosmetics effective June 2027.
PEG-12 Dimethicone/PPG-20 Crosspolymer Sensory Modifier
As an ethoxylated and propoxylated compound, it carries a risk of trace contamination with 1,4-dioxane and ethylene oxide, which are probable human carcinogens [2.1].
Phenoxyethanol Preservative
Generally well tolerated but can cause contact dermatitis or skin irritation in rare cases, particularly in sensitive individuals.
PEG/PPG-18/18 Dimethicone Emulsifier
Because it contains polyethylene glycol and polypropylene glycol it carries a risk of trace contamination with dioxane and ethylene oxide which are toxic byproducts of the manufacturing process [2.1].
Dioctyl Sodium Sulfosuccinate Surfactant
The Cosmetic Ingredient Review Expert Panel notes that this ingredient is a cumulative irritant and cautions against its use in formulations intended for prolonged skin contact if not formulated to minimize irritation.
Sodium Chloride Other
Frequently assigned a high comedogenic rating in dermatological assessments, presenting a credible risk of pore clogging and acne exacerbation in leave-on products.
Cetyl PEG/PPG-10/1 Dimethicone Emulsifier
Because it contains polyethylene glycol (PEG) and polypropylene glycol (PPG) chains, it carries a potential risk of trace contamination with 1,4-dioxane and ethylene oxide from the ethoxylation manufacturing process.
Isostearic Acid Skin Conditioning
Frequently flagged in dermatological databases as having a high comedogenic rating, meaning it has the potential to clog pores and exacerbate acne in susceptible individuals [2.5].
Ethylhexylglycerin Preservative
Recognized as a rare but emerging cause of allergic contact dermatitis, particularly in leave-on cosmetic products.
