Professional-C Serum

A superior vitamin C
L-ascorbic acid provides the essential qualities of a high-performance vitamin C serum: it penetrates the skin quickly, remains active in the skin, and supports the anti-ageing benefits of the Obagi Nu-Derm regime. According to Obagi's own user testing, the majority of users reported brighter, smoother, firmer-feeling skin, with many noticing improvement in as little as one week.*
Why vitamin C matters
As a key skin antioxidant, vitamin C helps to:
- Minimise the appearance of fine lines and wrinkles
- Brighten and even skin tone
- Improve skin texture
- Calm and soothe the skin
- Defend against environmental free-radical damage
Obagi's clinical testing indicates Professional-C offers notably better penetration than many other vitamin C serums.
*Professional-C Serum is not a sunscreen and should not be used as a substitute for sun protection. Daily use of a broad-spectrum high-SPF sunscreen is recommended as part of any skincare routine.
