Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Hamamelis Virginiana Extract
- Botanical extract for astringent and sebum control; mild irritation risk for sensitive skin at high concentrations.
- 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
- Sodium Hyaluronate Crosspolymer
- Crosslinked high-MW HA; forms surface hydrogel for long-lasting hydration, minimal penetration, physical film-forming.
- Sodium Cocoyl Amino Acids
- Mild amino acid surfactant; fine foam, low irritation; blend with other surfactants for cleansing power.
- Sarcosine
- Sarcosine, skin conditioning/pH buffer; check charge interaction with cationic surfactants.
- Potassium Aspartate
- Humectant and skin conditioner; amino acid derivative, gentle; 1-5% typical; good compatibility.
- Magnesium
- Not decoded yet
- Red Algae Extract
- Not decoded yet
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Caprylhydroxamic Acid
- Chelating agent to stabilize metal ions; often paired with antioxidants for system stability, used at low levels
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Glyceryl Stearate Citrate
- Emulsifying stabilizer and emollient at 2–5%; provides creamy texture, check compatibility with anionic surfactants
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Xylitylglucoside
- Polyol humectant with high water absorption and fresh feel; often co-used with propylene glycol for enhanced hydration.
- Anhydroxylitol
- Anhydrous xylitol, potent humectant; high hygroscopicity may cause stickiness at high levels.
- Xylitol
- Polyol humectant, sweet taste; water-soluble, high hygroscopy, excess draws moisture.
- Madecassoside
- Triterpenoid glycoside with soothing, repairing, and antioxidant effects; typical concentration 0.1-1%, suitable for sensitive or compromised skin, good stability.
- Hydrolysed Hyaluronic Complex
- Not decoded yet
- Sodium Acetylated Hyaluronate
- Acetylated HA; modified for hydrophobicity, improved penetration and non-tacky feel compared to standard HA.
- Magnesium Aspartate
- Magnesium aspartate; water-soluble chelant/conditioner. Use at 1-2%; check chelation efficiency.
- Zinc Gluconate
- Chelated zinc salt with antimicrobial and deodorizing effects; used in antiperspirants and oral care; has EU concentration limit.
- Copper Gluconate
- Copper gluconate; trace antioxidant/repair agent. Use <0.05%; high levels cause color change/irritation.
- Calcium Gluconate
- Chelator and conditioner, improves stability; water-soluble calcium source
