Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Tranexamic Acid
- Tranexamic acid for skin brightening; generally mild at low external doses.
- Dimethyl Isosorbide
- Dimethyl isosorbide as solvent and viscosity control; low toxicity, common use
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Kojic Acid
- Tyrosinase inhibitor for whitening; EU limit 1% in water, unstable and requires light protection, potential irritation.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Glycyrrhiza Glabra Root Extract
- Liquorice root extract for soothing and brightening; batch variability, watch polyphenol interactions
- Camellia Sinensis Leaf Extract
- Green tea extract for antioxidant/astringent; contains caffeine, possible irritation in sensitive skin.
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Sorbic Acid
- Preservative effective at low pH, often combined with sorbate salts; check regulatory limits
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
