FAQ

FAQ

Q: Why might my Obagi Professional-C Serum appear darker in colour?
A: Obagi Vitamin C Serums may naturally vary in colour from clear to deep amber due to the nature of the antioxidant. This variation is completely normal and does not affect the product's effectiveness. However, if the serum turns brown or develops an unusual odour, it may have oxidised and should be replaced.

Q: Is this serum suitable for sensitive skin?
A: The 20% concentration is best suited for those who have already built up a tolerance to vitamin C or who do not have sensitive skin. If you are new to vitamin C serums or have sensitive skin, our experts recommend starting with the Obagi Professional-C Serum 10% and gradually working up to higher concentrations.

Q: How long before I see results?
A: Some users notice improvements in skin brightness and hydration within 2-4 weeks of consistent use. More significant changes, such as reduction in fine lines, wrinkles, and hyperpigmentation, may take up to 12 weeks of daily application.

Q: Can I use this serum with other active ingredients?
A: Yes, Obagi Professional-C Serum can be layered with other skincare actives including retinoids, niacinamide, and AHAs/BHAs. However, if you experience any irritation, reduce frequency of use or speak to our skincare experts for personalised guidance.

Q: Is this product oil-free and non-comedogenic?
A: Yes, Obagi Professional-C Serum 20% is both oil-free and non-comedogenic, making it suitable for those prone to breakouts or with oily skin types.

£170.00

Product Overview - Obagi Professional-C Serum 20% | High-Potency Vitamin C Antioxidant Serum | 30ml


The Obagi Professional-C Serum 20% is a high-potency vitamin C antioxidant serum formulated with 20% L-Ascorbic Acid, the purest and most bioavailable form of vitamin C. This professional-grade treatment delivers powerful antioxidant protection whilst brightening skin tone, reducing the appearance of fine lines and wrinkles, and defending against environmental aggressors including UV damage, blue light, and infrared radiation.

Enriched with Sodium Hyaluronate to lock in moisture and prevent dryness, this fast-absorbing serum penetrates deep into the skin to stimulate collagen production and combat free radical damage. The formulation also includes Ascorbyl Glucoside, a stabilised vitamin C derivative that provides additional antioxidant benefits. Ideal for normal to oily skin types, this award-winning serum delivers a supercharged, hydrated glow for more youthful-looking skin.

Key Benefits at a Glance

Immediate Benefits:
Long-Term Benefits:

With consistent daily use, Obagi Professional-C Serum 20% helps to minimise the appearance of fine lines and wrinkles by stimulating collagen production and protecting existing collagen fibres from oxidative damage. The high concentration of L-Ascorbic Acid works to fade hyperpigmentation and dark spots, promoting a more even, clarified complexion over time.

The serum's potent antioxidant properties help to combat oxidative stress induced by blue light and infrared radiation, which are known contributors to premature skin ageing. Regular application supports the skin's natural repair processes and helps maintain a firmer, more resilient skin texture with improved elasticity.

How Will It Feel on My Skin?

This lightweight serum absorbs quickly into the skin without leaving a greasy or oily residue. Upon application, you may experience a slight tingling sensation, which is normal and indicates the active ingredients are working. This sensation typically diminishes with continued use as your skin acclimatises to the formulation. The serum leaves skin feeling refreshed, smooth, and hydrated.

Who Is It Suitable For?
