Can I use this with other active ingredients like retinol?

Yes, but use antioxidants in the morning and retinol at night. The vitamin C in this serum can actually help stabilize retinol when used in alternating routines.

Will this serum cause irritation on sensitive skin?

The pH-optimized formula is gentler than many vitamin C serums. Start every other day and build tolerance. If irritation occurs, reduce frequency or apply over moisturizer initially.

How long before I see results?

Antioxidant protection begins immediately, but visible improvements in brightness and tone typically appear within 4-6 weeks of consistent daily use.

Should I refrigerate this serum?

Not necessary, but storing in a cool, dark place helps maintain potency. The stabilized formula is designed to remain effective at room temperature.

About U Antioxidant Serum

This advanced formula combines stabilized vitamin C, vitamin E, and ferulic acid in a lightweight, fast-absorbing base that penetrates deeply to provide comprehensive cellular protection.

Formulated with a pH-optimized delivery system, this serum ensures maximum stability and bioavailability of active ingredients. The lightweight texture makes it suitable for all skin types, including sensitive skin that may not tolerate other high-potency antioxidant formulations. Regular use helps strengthen the skin's natural defense mechanisms while promoting a brighter, more even complexion.

How to Use

Apply 2-3 drops to clean, dry skin every morning after cleansing and before moisturizer. Gently pat into face and neck, avoiding the immediate eye area. Allow to fully absorb before applying SPF. Start with every other day for the first week if you have sensitive skin, then increase to daily use as tolerated.

Pro Tip from Our Clinicians

Layer under mineral sunscreen for enhanced photoprotection. This serum works beautifully as a prep treatment before IPL or chemical peels, as the antioxidants help minimize post-treatment inflammation and support faster healing.
