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: Hydrating products draw water into the upper skin layer (glycerin, hyaluronate, panthenol, ectoin) — one humectant is enough. Without barrier ingredients (niacinamide, ceramides, oils) the effect does not last.
When:
  • leave-on
  • morning
  • evening
morning and evening, under a moisturiser
When to expect an effect: hydration — days; wrinkles and spots — no reliable timeline; hydration — immediately; lasting effect — 2–4 weeks; soothing and less tightness — within days; soothing — days; barrier — 2–4 weeks; wrinkles — 8 weeks, a modest effect
What is normal: a slightly tacky texture; 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
  • Snail Secretion Filtrate works · the active ingredient — what the product is for; form: snail secretion filtrate
  • Betaine base: coating, fillers · draws water in and holds it in the upper layer of the skin
  • Caprylic/Capric Triglyceride base: coating, fillers · a coconut-oil fraction, a light emollient and carrier of actives; does not clog pores
  • Butylene Glycol base: coating, fillers · a humectant and solvent: it makes the texture lighter and helps actives spread. Better tolerated than propylene glycol.
  • Cetearyl Olivate base: coating, fillers · makes hair softer and easier to comb
  • Sorbitan Olivate base: coating, fillers · keeps the water and oil parts from separating
  • Cetearyl Alcohol base: coating, fillers · a fatty-alcohol blend (C16–C18), an emulsifier and thickener, does not dry the skin; paired with ceteareth-20 — 4 of 5; rarely clogs pores in leave-on face products
  • Carbomer base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Ethyl Hexanediol base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Phenoxyethanol base: coating, fillers · the most widespread cosmetic preservative: it keeps the product sterile. Permitted in the EU up to 1 %, recognised as safe at that level.
  • Arginine base: coating, fillers · amino acids, lipids and sugars akin to the skin’s own components — support for its barrier
  • Dimethicone base: coating, fillers · form a smooth film and shine; inert and not absorbed — a preference question, not a safety one
  • Sodium Polyacrylate label wording · an allergen (sodium (salt)) — matters when limiting salt, for example with blood pressure; the label says it is absent
  • Sodium Hyaluronate works · the active ingredient — what the product is for; form: sodium hyaluronate
  • Allantoin works · the active ingredient — what the product is for; form: allantoin
  • Palmitic Acid base: coating, fillers · a fatty acid (C16), a thickener and soap component; rarely clogs pores in leave-on face products
  • Panthenol works · the active ingredient — what the product is for; form: panthenol
  • Xanthan Gum base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Stearic Acid base: coating, fillers · in tablets — a pressing lubricant, in creams — a thickener and soap component; rarely clogs pores in leave-on face products
  • Adenosine works · the active ingredient — what the product is for; form: adenosine
  • 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
  • Myristic Acid base: coating, fillers · a fatty acid (C14), gives dense foam in cleansers; may clog pores in leave-on face products
