How the score is calculated
  • Actives and evidence0.8Actives with strong evidence: 1 of 5
  • Active concentration0.9After the 1 % line: lactobionic acid (pha), tea tree oil — the concentration is likely token
  • Completeness for the purpose0.9For “acne and blackheads” — 86 %; without a retinoid — the main tool against new plugs; could be added without conflict: retinoid; below threshold: niacinamide (vitamin b3), tea tree oil; a broad formula across 3 purposes
  • Tolerance0.9Debatable ingredient groups: fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • oily skin
  • acne-prone
  • dry skin
  • pregnancysalicylates — ask a doctor
  • sensitive skinat 10 % flushing is possible
  • rosaceaask a dermatologist
  • childrenage-based dose, with a doctor
  • atopic skinfragrance is a common trigger
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
  • 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: Acne products work on four fronts: dissolve plugs (acids), calm inflammation (azelaic acid, niacinamide, zinc), kill bacteria (benzoyl peroxide, tea tree) and prevent new plugs (a retinoid). One active per front is enough; two or three different fronts work noticeably better.
When:
  • leave-on
  • morning
  • evening
morning and evening, on clean skin
When to expect an effect: tone, pores — 4–8 weeks; sebum — 2–4; pores, blackheads — 4–8 weeks; sebum, shine — 2–4 weeks; hydration — days; smoothness — 2–4 weeks; acne — 6–12 weeks
What is normal: mild flushing in the first days at high concentration; mild dryness and flaking in the first weeks; mild dryness; mild tingling in the first days; dryness, mild stinging

Questions: fragrance and its allergens: fragrance — 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

  • Niacinamide (vitamin B3) + Salicylic acid (BHA) — reinforce each otherniacinamide cuts sebum and redness, the BHA clears pores — an acne classic
  • Niacinamide (vitamin B3) + Zinc PCA — reinforce each otherboth reduce sebum and inflammation — a classic pair for oily skin
  • 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
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Niacinamide works · the active ingredient — what the product is for; form: niacinamide
  • Hamamelis Virginiana (Witch Hazel) 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

  • Sesame Amino Acids base: coating, fillers · amino acids and PCA — substances the skin itself keeps in the outer layer to hold water; in a product they are humectants copying its own set
  • Zinc PCA works · the active ingredient — what the product is for; form: zinc PCA
  • 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.

  • Glyceryl Caprylate base: coating, fillers · a glycerin–caprylic acid ester: an emollient and co-emulsifier that also curbs microbial growth — boosts the preservative and lets the maker skip “heavy” ones

  • Inulin base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
