Ingredients explained
- Purified Water
- Deionized or purified water serving as the formulation solvent base; requires protection from microbial contamination, typically constitutes the majority of the formula.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- 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.
- Saccharide Isomerate
- Novel polyol humectant with skin feel improvement; high hydration, suitable for lightweight formulas.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
- Rice Phytoceramide
- Not decoded yet
- Zaminkand Root Phytoceramide
- Not decoded yet
- Phospholipids
- Biomimetic repair and emollient, mimics skin lipids; typically processed at low temps, may be sticky at high levels
- Sphingolipids
- Biomimetic membrane lipids for repairing skin barrier and stratum corneum; highly effective for barrier impairment
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Lactic Acid
- AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
