Formulation view A water-based serum featuring L-ascorbic acid and niacinamide, supported by tocopherol and a carbomer gel matrix neutralized by triethanolamine. Suitable for combining brightening and oil control in combination skin. A formulator observes that high-strength pure vitamin C stability is a challenge; strict light and air protection are required, and the lack of chelators may increase discoloration risk over time.

Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- 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.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Triethanolamine
- Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
