How the score is calculated
  • Filters and spectrum1.0Broad spectrum UVA + UVB: diethylamino hydroxybenzoyl hexyl benzoate (uvinul a plus), ethylhexyl triazone (uvinul t 150), bisoctrizole (tinosorb m), diethylhexyl butamido triazone (uvasorb heb)
  • Filter concentration0.9Actives sit above the 1 % line — by list order a working concentration is 93 % likely
  • Completeness for the purpose1.0For “sun protection” — 96 %; vitamin c; could be added without conflict: vitamin c; below threshold: bisoctrizole (tinosorb m); a narrow formula for one purpose
  • Tolerance1.0No ingredients from irritant or allergen lists

Free from:
  • alcohol (alcohol denat) · by the listthe list has no ingredient of the “denatured alcohol” group — evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores
  • 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.
  • 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; tone, pores — 4–8 weeks; sebum — 2–4; wrinkles — 8 weeks, a modest effect
What is normal: a light shine and a film feel on the skin; a white cast with mineral filters; mild flushing in the first days at high concentration; nothing special — well tolerated

Questions: no debatable ingredients in the formula

  • Aqua 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
  • Dibutyl Adipate base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • Propanediol base: coating, fillers · a humectant and solvent from corn sugar: it holds water and helps actives dissolve. A gentler replacement for propylene glycol.
  • Diethylamino Hydroxybenzoyl Hexyl Benzoate works · the active ingredient — what the product is for; form: diethylamino hydroxybenzoyl hexyl benzoate
  • Polymethylsilsesquioxane base: coating, fillers · removes transparency, making the product white or cloudy
  • Ethylhexyl Triazone works · the active ingredient — what the product is for; form: ethylhexyl triazone
  • Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (nano works · the active ingredient — what the product is for; form: bisoctrizole
  • Niacinamide works · the active ingredient — what the product is for; form: niacinamide
  • Coco-Caprylate/Caprate base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • Caprylyl Methicone base: coating, fillers · form a smooth film and shine; inert and not absorbed — a preference question, not a safety one
  • Diethylhexyl Butamido Triazone works · the active ingredient — what the product is for; form: diethylhexyl butamido triazone
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • 1,2-Hexanediol base: coating, fillers · a solvent and humectant with antimicrobial action: it helps the product keep without classic preservatives.
  • Butylene Glycol base: coating, fillers · a humectant and solvent: it makes the texture lighter and helps actives spread. Better tolerated than propylene glycol.
  • Pentylene Glycol base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Behenyl Alcohol base: coating, fillers · emulsifiers and thickeners; not “alcohol” in the everyday sense — they do not dry the skin; rarely clog pores
  • Poly C10-30 Alkyl Acrylate base: coating, fillers · makes the product thicker or thinner
  • Polyglyceryl-3 Methylglucose Distearate base: coating, fillers · keeps the water and oil parts from separating
  • Decyl Glucoside base: coating, fillers · one of the gentlest cleansing ingredients: a sugar surfactant that barely disturbs the skin barrier.
  • Oryza Sativa (Rice) Extract base: coating, fillers · plant and algae extracts and floral waters: flavouring and marketing components — at these shares there is no proven effect on the skin; rare reactions in people allergic to that particular plant
  • Tromethamine base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Carbomer base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Acrylates/C10-30 Alkyl Acrylate Crosspolymer base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Sodium Stearoyl Glutamate label wording · an allergen (sodium (salt)) — matters when limiting salt, for example with blood pressure; the label says it is absent
  • Polyacrylate Crosspolymer-6 base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Ethylhexylglycerin base: coating, fillers · a preservative booster and skin-conditioning ingredient: it barely preserves on its own but helps phenoxyethanol work and lowers the amount needed.
  • Adenosine works · the active ingredient — what the product is for; form: adenosine
  • Xanthan Gum base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • T-Butyl Alcohol base: coating, fillers · a denaturant in trace amounts: it is added so the alcohol part of the formula cannot be drunk. At this level it does not dry the skin — it is not the alcohol people worry about in skincare
  • 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
  • Oryza Sativa (Rice) Germ Extract base: coating, fillers · plant and algae extracts and floral waters: flavouring and marketing components — at these shares there is no proven effect on the skin; rare reactions in people allergic to that particular plant
  • Camellia Sinensis Leaf Extract base: coating, fillers · an ingredient from the European cosmetic ingredient inventory; what exactly it does in this product is not described here yet
  • Saccharum Officinarum (Sugarcane) Extract base: coating, fillers · plant and algae extracts and floral waters: flavouring and marketing components — at these shares there is no proven effect on the skin; rare reactions in people allergic to that particular plant

  • Lactobacillus/Pumpkin Ferment Extract base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Bacillus/Soybean Ferment Extract base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Aspergillus Ferment base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
