Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Tranexamic Acid
- Tranexamic acid for skin brightening; generally mild at low external doses.
- Diethylhexyl Carbonate
- Light emollient for silky texture; non-comedogenic, suits most skin types.
- Alpha-Arbutin
- Whitening antioxidant, inhibits tyrosinase; use 1-2%, avoid strong acids
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Methyl Methacrylate Crosspolymer
- MMA crosspolymer for durable water-soluble film; high doses may create occlusion
- Sodium Polyacryloyldimethyl Taurate
- Sodium polyacryloyldimethyl taurate for emulsion stabilization and thickening; ionic polymer, check ion compatibility.
- Methyl Gluceth-20
- Not decoded yet
- Hydrogenated Polydecene
- Hydrogenated polydecene, light mineral oil alternative, low comedogenic; silky, non-greasy.
- Dipotassium Glycyrrhizinate
- Potent anti-inflammatory and soothing agent; often combined with glycyrrhiza extracts; stability depends on pH and cationic system compatibility.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Butyrospermum Parkii
- African oil/fat/wax; clarify form (oil, butter, or powder) as function depends on it.
- Ammonium Acryloyldimethyltaurate/VP Copolymer
- Cationic polymer providing suspension, thickening, and conditioning; often paired with anionic thickening systems, low usage, imparts slip.
- Trideceth-10
- Not decoded yet
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Aloe Barbadensis Leaf Extract
- Aloe vera leaf extract for soothing and humectant; monitor polysaccharide level and endotoxins
- Alisma Plantago Aquatica Extract
- Plant extract, often used as a skin conditioning agent.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Centella Asiatica Extract
- Centella asiatica extract for soothing/repair; low irritation, common in sensitive skin products.
- Maltodextrin
- High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.
