Brightening Vitamin C Serum OEM Manufacturing
Our Brightening Vitamin C Serum is a clinical-strength formula featuring 20% L-ascorbic acid (the most bioavailable form of vitamin C), enhanced with ferulic acid and vitamin E for synergistic antioxidant protection. This lightweight serum targets dark spots, uneven skin tone, and signs of aging while providing powerful environmental protection. The stabilized formula maintains potency for up to 6 months after opening.
Key Benefits
- 20% L-ascorbic acid brightens skin and fades dark spots within 4 weeks
- Ferulic acid + vitamin E boost antioxidant protection by 8x compared to vitamin C alone
- Stimulates collagen production for firmer, more elastic skin
- Protects against UV-induced free radical damage and photoaging
- Lightweight, fast-absorbing texture layers perfectly under sunscreen and makeup
Formulation Science
L-ascorbic acid is notoriously unstable, oxidizing quickly in water-based formulas. Our proprietary stabilization system uses a low pH (3.5) formula with ferulic acid as a natural preservative, extending potency to 6 months. The addition of propylene glycol creates an anhydrous environment that slows oxidation. Clinical testing shows 94% stability at 6 months, versus 40% for standard vitamin C serums.
Customization Options
We offer comprehensive OEM/ODM services including vitamin C derivative selection (L-ascorbic acid, sodium ascorbyl phosphate, ascorbyl glucoside, tetrahexyldecyl ascorbate), concentration adjustment (5%-25%), additional actives (hyaluronic acid, niacinamide, peptides), texture options, and packaging design. Airless pump bottles and glass dropper bottles available.
Frequently Asked Questions
A: L-ascorbic acid is the most bioavailable form of vitamin C, with clinical studies proving maximum efficacy at 15-20% concentration. Other derivatives require conversion in the skin, reducing potency.
A: Our proprietary stabilization system maintains 94% potency for 6 months after opening. Store in a cool, dark place or refrigerator for extended shelf life.
A: Yes! We offer 5% (sensitive skin), 10% (beginner), 15% (maintenance), and 20% (maximum efficacy) concentrations. We can also use gentler derivatives like sodium ascorbyl phosphate.
A: Vitamin C pairs well with niacinamide and sunscreen. For retinol, use vitamin C in the morning and retinol at night. We can also create a combined formula.
A: We recommend airless pump bottles (15-30ml) to minimize air exposure, or dark glass dropper bottles. Both options protect the formula from light and oxidation.
