How the score is calculated
  • Filters and spectrum1.0Broad spectrum UVA + UVB: ethylhexyl salicylate (octisalate), bemotrizinol (tinosorb s), ethylhexyl triazone (uvinul t 150), avobenzone, mexoryl 400 (mce), diethylamino hydroxybenzoyl hexyl benzoate (uvinul a plus), drometrizole trisiloxane (mexoryl xl), terephthalylidene dicamphor sulfonic acid (mexoryl sx)
  • Filter concentration0.9After the 1 % line: mexoryl 400 (mce), diethylamino hydroxybenzoyl hexyl benzoate (uvinul a plus), drometrizole trisiloxane (mexoryl xl), terephthalylidene dicamphor sulfonic acid (mexoryl sx) — the concentration is likely token
  • Completeness for the purpose1.0For “sun protection” — 96 %; vitamin c; could be added without conflict: vitamin c; below threshold: bemotrizinol (tinosorb s); a narrow formula for one purpose
  • Tolerance0.9Debatable ingredient groups: denatured alcohol
  • adults
  • children
  • pregnancyallowed per the leaflet

Free from:
  • sulfates (SLS/SLES) · by the listthe list has no ingredient of the “ammonium laureth sulfate (ALES), ammonium lauryl sulfate (ALS), sodium coco-sulfate, sodium laureth sulfate (SLES), sodium lauryl sulfate (SLS), sodium myreth sulfate, TEA-lauryl sulfate” group — a cleansing surfactant from the sulfate family but with an ethoxylated chain: it cleanses more gently than lauryl sulfate. Still not for those looking for a sulfate-free product.
  • formaldehyde releasers · by the listthe list has no ingredient of the “formaldehyde releasers” group — preservatives that slowly release formaldehyde; allowed at low levels but a frequent cause of contact allergy
  • isothiazolinones (MIT/MCI) · by the listthe list has no ingredient of the “isothiazolinone preservatives (MIT/MCI)” group — preservatives; banned in EU leave-on products and limited in rinse-off (0.0015%) — a frequent cause of contact allergy
  • fragrance · by the listthe list has no ingredient of the “fragrance and its allergens” group — the fragrance and its aromatic components; the EU requires 26 of them to be listed separately — matters to people allergic to fragrance, does not affect how the product works
  • parabens · by the listthe list has no ingredient of the “parabens” group — preservatives; methyl- and ethylparaben are recognised as safe at permitted levels, propyl- and butyl- are limited by the EU to 0.14 %; a frequent buyer question rather than proven harm
  • mineral oils and petrolatum · by the listthe list has no ingredient of the “petrolatum and mineral oils” group — purified cosmetic-grade petroleum products: form a protective barrier film; safety is established, a preference question; 0–2 of 5 (depends on the raw-material source), cosmetic white oil per DiNardo (2005) is non-comedogenic
  • soap · by the listthe list has no ingredient of the “potassium soap (potassium cocoate), plant soap base (sodium palmate, sodium cocoate), tallow soap base (sodium tallowate)” group — liquid soap: fatty acids boiled with alkali. It cleanses well, but its acidity is around 9-10 against 5 for skin, which is why it often leaves tightness. The product is rinsed off, so the question is tolerance.
  • silicones · by the listthe list has no ingredient of the “silicones” group — form a smooth film and shine; inert and not absorbed — a preference question, not a safety one
  • gelatin in the coating · by the listthe list has no ingredient of the “vegetarian coating” group — a plant-based tablet coating instead of gelatin; it keeps moisture out and makes swallowing easier
  • toning dyes · by the listthe list has no ingredient of the “violet toning dyes” group — direct dyes that settle on the hair surface and cancel the yellow cast of blonde; they wash out in 1–3 washes and leave a lilac tint if left too long; HC Blue 2 and Disperse Violet 1 are known contact allergens of hair dyes
  • tar · by the listthe list has no ingredient of the “wood (birch) tar” group — a traditional remedy for dandruff and itching with a sharp smell; it reduces flaking, but can irritate a sensitive scalp and dries the hair
What for: Sun protection works only with a broad spectrum: you need a UVB filter (burn) and a UVA filter (ageing, pigmentation) — a single broad-spectrum filter covers both. Antioxidants — vitamin C, vitamin E, ferulic acid — boost protection but do not replace filters.
When:
  • leave-on
  • morning
in the morning, as the last care step, 15 minutes before going out
When to expect an effect: protection — right after it sinks in; reapply every 2 hours in the sun
What is normal: a light shine and a film feel on the skin; a white cast with mineral filters; a light film feel; no white cast; a light texture, easily washed off with water

Strengths: filters and spectrum, filter concentration, completeness for the purpose, tolerance

Questions: denatured alcohol — evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores

  • Avobenzone + Bemotrizinol (Tinosorb S) — reinforce each otherTinosorb S stabilises avobenzone and widens the spectrum
  • Aqua/Water/Eau base: coating, fillers · water — the solvent and base; listed first because there is more of it than anything else; in supplements — part of the capsule shell
  • Alcohol Denat questions · evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores
  • Triethyl Citrate base: coating, fillers · a citric acid ester: in tablets a coating plasticiser, in deodorants it slows the bacterial enzymes that make sweat smell
  • Diisopropyl Sebacate base: coating, fillers · a light emollient solvent: dissolves oil-soluble filters and keeps a fluid weightless, without a greasy feel.
  • Silica base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Ethylhexyl Salicylate works · the active ingredient — what the product is for; form: ethylhexyl salicylate
  • Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine works · the active ingredient — what the product is for; form: bemotrizinol
  • Ethylhexyl Triazone works · the active ingredient — what the product is for; form: ethylhexyl triazone
  • Butyl Methoxydibenzoylmethane works · the active ingredient — what the product is for; form: avobenzone
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Propanediol base: coating, fillers · a humectant and solvent from corn sugar: it holds water and helps actives dissolve. A gentler replacement for propylene glycol.
  • C12-22 Alkyl Acrylate/Hydroxyethylacrylate Copolymer base: coating, fillers · a film former: holds the filters in an even layer and gives water resistance.
  • Sodium Citrate base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate works · the active ingredient — what the product is for; form: methoxypropylamino cyclohexenylidene ethoxyethylcyanoacetate
  • Perlite base: coating, fillers · a volcanic mineral absorbent: soaks up sebum and gives a matte finish, does not act on the skin.
  • Tocopherol base: coating, fillers · vitamin E at hundredths of a percent: keeps the oils of the formula (a cream or a capsule fill) from going rancid; at that share it protects the product, it is not vitamin E as an active
  • Caprylic/Capric Triglyceride base: coating, fillers · a coconut-oil fraction, a light emollient and carrier of actives; does not clog pores
  • Acrylates/C10-30 Alkyl Acrylate Crosspolymer base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Caprylyl Glycol base: coating, fillers · a humectant that also holds bacteria back, which is why it often replaces part of the preservative.
  • Citric Acid base: coating, fillers · acidity regulator
  • Diethylamino Hydroxybenzoyl Hexyl Benzoate works · the active ingredient — what the product is for; form: diethylamino hydroxybenzoyl hexyl benzoate
  • Drometrizole Trisiloxane works · the active ingredient — what the product is for; form: drometrizole trisiloxane
  • Hydroxyethylcellulose base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Terephthalylidene Dicamphor Sulfonic Acid works · the active ingredient — what the product is for; form: terephthalylidene dicamphor sulfonic acid
  • Triethanolamine base: coating, fillers · a pH adjuster and thickener neutraliser; rarely clogs pores in leave-on face products
  • Trisodium Ethylenediamine Disuccinate base: coating, fillers · bind hard-water metals so the formula stays stable and the foam works
