Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycolic Acid
- Glycolic acid for exfoliation; requires buffering at concentrations >10%, avoid combination with other acids.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Tetrasodium EDTA
- Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Glycyrrhiza Glabra Root Extract
- Liquorice root extract for soothing and brightening; batch variability, watch polyphenol interactions
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
