Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Methylpropanediol
- Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Milk Thistle Fruit Extract
- Not decoded yet
- Ascorbyl Methylsilanol Pectinate
- Silicon-based Vitamin C derivative for antioxidant activity and viscosity control; superior stability compared to traditional Vitamin C, suitable for formulation.
- Lecithin
- Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.
- Carnosine
- Dipeptide skin conditioner with antioxidant and buffering properties; used in synergy with other actives.
- Melatonin
- Melatonin, antioxidant; verify topical stability
- Cyclodextrin
- Cyclodextrin; used as a stabilizer or solubilizer to improve solubility of active ingredients and fragrances
- Thioctic Acid
- Alpha-lipoic acid; potent antioxidant; poor water solubility, often used as ester derivatives
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Ascorbic Acid
- Vitamin C, potent antioxidant requiring acidic environment for stability; oxidizes and discolors easily, needs light and air protection, concentration 1-10%, pure L-ascorbic acid is more irritating.
