Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Alpha-Arbutin
- Whitening antioxidant, inhibits tyrosinase; use 1-2%, avoid strong acids
- Hexylresorcinol
- Tyrosinase inhibitor for whitening; typical range 0.1-1.5%, potential irritation at high levels, control pH.
- Aminopropyl Ascorbyl Phosphate
- Stable Vitamin C derivative; water-soluble antioxidant and brightener, solubility pH-dependent
- Hexapeptide-2
- Not decoded yet
- Tetrahexyldecyl Ascorbate
- Lipophilic Vitamin C derivative, antioxidant and brightening; more stable than VC, oil-soluble, must pair with oil phase
- Superoxide Dismutase
- Enzymatic antioxidant breaking down superoxide radicals; used as bioactive at low levels, requires strict temperature control to prevent inactivation.
- Ethylbisiminomethylguaiacol Manganese Chloride
- Manganese chelator/antioxidant stabilizer; synergizes with Vit E; avoid iron contact
- Lactobionic Acid
- Polyhydroxy acid for pH buffering; gentle, check stability at high levels
- Undecylenoyl Phenylalanine
- Synthetic peptide emollient regulating sebum and hydration; low comedogenic, used in acne-prone and oily skin formulas.
- Tetrahydrodiferuloylmethane
- Not decoded yet
- Glutathione
- Antioxidant and brightening agent; unstable, requires antioxidants and protection from light.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer
- Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.
- Dimethylmethoxy Chromanol
- Ergothioneine analog antioxidant; stabilizes formula, protect from light.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Polyglyceryl-3 Cetyl Ether
- Not decoded yet
- 4-Butylresorcinol
- Not decoded yet
- Papain
- Protease for mild exfoliation; concentration must be controlled to avoid irritation.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Oxothiazolidinecarboxylic Acid
- Thiazolidine carboxylic acid derivative used for skin conditioning at low levels; check purity and solvent residues.
- Phenylethyl Resorcinol
- Phenylethyl resorcinol, antioxidant/whitening at 0.1–1%; inhibits tyrosinase, watch compatibility with high-dose VC.
- Paeonia Suffruticosa Root Extract
- Paeonia root extract, skin protecting agent with antioxidants to defend against environmental damage
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Decapeptide-12
- Not decoded yet
- Tetrapeptide-30
- Not decoded yet
- Dipotassium Glycyrrhizate
- Dipotassium glycyrrhizinate for moisturizing/soothing; inhibits 5-LOX, water-soluble, for sensitive skin.
- Potassium Azeloyl Diglycinate
- SKIN CONDITIONING
- Octadecenedioic Acid
- Unsaturated dicarboxylic acid for thickening and rheology; used as gel or emulsion thickener, low irritation
- Nonapeptide-1
- Nonapeptide-1 for hair/skin conditioning; enhances shine and strength, low irritation.
- Succinic Acid
- Dicarboxylic acid used as a buffer and natural metabolite; slight flavoring effect, low irritation
- Tranexamic Acid
- Tranexamic acid for skin brightening; generally mild at low external doses.
- Hydroxyacetophenone
- Hydroxyacetophenone as antioxidant; often boosts Vitamin C, works in acidic pH.
- Cyclodextrin
- Cyclodextrin; used as a stabilizer or solubilizer to improve solubility of active ingredients and fragrances
- Saccharomyces Lysate Extract
- Yeast lysate humectant and conditioner; rich in amino acids and NMF, strong barrier repair
- Sodium Sulfite
- Sulfite antioxidant to prevent oxidation; sulfites are known allergens and must be strictly declared on labels.
