How to Use
After cleansing and toning, apply 3–4 drops of Professional-C® Serum 10% to the face and neck — morning and/or evening. Press gently into skin and allow to absorb before applying moisturizer and SPF.

Key Ingredients

L-Ascorbic Acid (10%) — The gold-standard, most bioavailable form of Vitamin C; at 10%, it provides effective antioxidant protection and brightening with excellent tolerability for sensitive skin and new users
Professional Tips
If you're new to Vitamin C serums, starting at 10% is the ideal approach — allow your skin 4–6 weeks to acclimate before considering a step up to Professional-C® Serum 15% or 20%. Vitamin C oxidizes over time; store your serum in a cool, dark place and replace when the color turns orange or brown. Apply before moisturizer for maximum efficacy.
