Formulation view Niacinamide-led serum with antioxidants like ascorbyl phosphate, CoQ10, and tocopheryl acetate. Silicones and esters provide lightweight occlusion, while hyaluronic acid and panthenol hydrate. Modified starch absorbs oil, ideal for combination skin. Factory observation: Coexisting vitamin actives demand strict light and oxidation barrier packaging to prevent discoloration from redox reactions.

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
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Cetyl Dimethicone
- Silicone emulsifier/conditioner; excellent slip, hydrophobic, non-comedogenic.
- Ethylhexyl Stearate
- Synthetic ester emollient and emulsifier; oil-soluble, light feel, low comedogenicity, suitable for oily skin.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Aluminum Starch Octenylsuccinate
- Modified starch absorbent at 1–10%; for powder products, oil-absorbing without heavy feel
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Sorbitol
- Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Ubiquinone
- Coenzyme Q10 analog used as an antioxidant; prone to discoloration, needs protection from light and air.
- Folic Acid
- Folic acid, Vitamin B9, used for skin conditioning to support cellular metabolism
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Ammonium Acryloyldimethyltaurate/Vp Copolymer
- Cationic polymer providing suspension, thickening, and conditioning; often paired with anionic thickening systems, low usage, imparts slip.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer
- Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.
- Dehydroxanthan Gum
- Modified polymer for emulsion stability and film forming; high viscosity impact.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- 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
