How the score is calculated
  • Actives and evidence0.7Actives with strong evidence: 1 of 5
  • Active concentration1.0Actives sit above the 1 % line — by list order a working concentration is 99 % likely
  • Completeness for the purpose0.9For “skin texture and pores” — 93 %; glycolic acid; without a retinoid — it renews the skin deeper than acids; could be added without conflict: glycolic acid, retinoid; below threshold: niacinamide (vitamin b3); a formula with one main purpose
  • Tolerance1.0No ingredients from irritant or allergen lists
  • adults
  • pregnancyallowed per the leaflet

  • acne-pronemay clog pores in leave-on face products
  • sensitive skinat 10 % flushing is possible
  • rosaceaask a dermatologist
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.
  • 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: Bumps and enlarged pores are smoothed by acids (glycolic, lactic, mandelic, PHA, salicylic) — one is enough; niacinamide makes pores less visible, a retinoid renews the skin more deeply. Pores do not “close” — they become less noticeable.
When:
  • leave-on
  • morning
  • evening
morning and evening, on clean skin
When to expect an effect: tone, pores — 4–8 weeks; sebum — 2–4; softness — right away; dryness — 1–2 weeks; hydration — immediately; lasting effect — 2–4 weeks; soothing — days; barrier — 2–4 weeks; wrinkles — 8 weeks, a modest effect
What is normal: mild flushing in the first days at high concentration; nothing special — well tolerated

Questions: no debatable ingredients in the formula

  • Hyaluronic acid + Panthenol (pro-vitamin B5) — reinforce each othertwo humectants with different action: moisture plus soothing
  • Bifida Ferment Lysate base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Galactomyces Ferment Filtrate base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Butylene Glycol base: coating, fillers · a humectant and solvent: it makes the texture lighter and helps actives spread. Better tolerated than propylene glycol.
  • Methyl Gluceth-20 base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Water 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
  • Niacinamide works · the active ingredient — what the product is for; form: niacinamide
  • PEG-90 base: coating, fillers · coating glazing agent
  • 1,2-Hexanediol base: coating, fillers · a solvent and humectant with antimicrobial action: it helps the product keep without classic preservatives.
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Squalane works · the active ingredient — what the product is for; form: squalane (saturated, from olive or sugarcane)
  • Alteromonas Ferment Extract base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Silk 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
  • Goat Milk 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
  • Sodium Hyaluronate works · the active ingredient — what the product is for; form: sodium hyaluronate
  • Panthenol works · the active ingredient — what the product is for; form: panthenol
  • Adenosine works · the active ingredient — what the product is for; form: adenosine
  • Glycereth-26 base: coating, fillers · an ethoxylated glycerin, a humectant; does not clog pores
  • Xanthan Gum base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Polyglyceryl-3 Distearate base: coating, fillers · keeps the water and oil parts from separating
  • Glyceryl Stearate SE base: coating, fillers · self-emulsifying glyceryl stearate with added sodium or potassium stearate — the additive is what makes it more comedogenic than the neutral form; may clog pores in leave-on face products
  • Glyceryl Stearate Citrate base: coating, fillers · the basic cream emulsifier (neutral NSE form); the self-emulsifying SE form with added potassium stearate is a separate entry, 3 of 5; does not clog pores
  • Polyglyceryl-3 Methylglucose Distearate base: coating, fillers · keeps the water and oil parts from separating
  • Carbomer base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Tromethamine base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • 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.
  • Caprylyl Glycol base: coating, fillers · a humectant that also holds bacteria back, which is why it often replaces part of the preservative.
  • Tropolone base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • Disodium EDTA base: coating, fillers · bind hard-water metals so the formula stays stable and the foam works
