A highly concentrated vitamin C serum with 20% L-ascorbic acid, the purest form of vitamin C. It brightens dull skin, helps defend against environmental damage and visibly improves fine lines and uneven tone.
Key benefits
- Brighter, more radiant-looking skin
- Antioxidant protection against daily environmental stress
- Softer appearance of fine lines and wrinkles
- Helps create a more even-looking skin tone
Best for
Normal to oily and combination skin, and experienced vitamin C users. If you are new to vitamin C or have sensitive skin, the Professional-C Serum 10% is a gentler alternative.
How to use
Each morning after cleansing and toning, apply 5–7 drops to the face, avoiding the eyes, nose and lips. Follow with moisturiser and sunscreen. A slight tingling is normal and should settle with continued use. Use within 3–6 months of opening and store in a cool, dark place.
Clinic tip
Vitamin C in the morning with SPF 50 is the foundation of every routine Jo recommends, and helps maintain your glow between peels and laser.
