Frequently Asked

Why does this have 3 forms of Vitamin C?
Each form works at different depths. L-Ascorbic is most potent; Glyceryl Ascorbate and Magnesium Ascorbyl Phosphate provide sustained, deeper delivery.
Should I use this morning or night?
Morning is ideal. Vitamin C provides antioxidant protection against UV and pollution throughout the day. Always follow with sunscreen.
Will this oxidize quickly?
Our formula includes Ferulic Acid which stabilizes Vitamin C. Store in a cool, dry place away from direct sunlight.
Can I use this with retinol?
Yes! Use Vitamin C in the morning and retinol at night. This is the gold standard routine recommended by dermatologists.
