How it works


Free radicals are created by the skin as a response to the environment, which can cause premature ageing.  Obagi Pro-C serums neutralise free radicals to prevent skin cell damage.  They contain professional strength Vitamin C which has been proven effective in treating sun damaged skin, and helps protect the skin from future sun damage.

It also stimulates collagen production, helping your skin stay firm and supple, while also working to reduce inflammation and increase hydration.

They provide up to 2x better penetration than other Vitamin C serums and stay stable for longer.


Obagi Professional-C Serums are not just another antioxidant product. Clinical studies have shown that Obagi Professional-C Serums offer significantly better penetration than other Vitamin C serums and are absorbed up to 5x better.

*Obagi Professional-C Serums are not sun protectors, and should not be used as a sun protection alternative. Daily use of a high SPF is recommended as part of any skin care routine.

Success Stories

Experience the Benefits of Vitamin C 

Read what real women have to say about their experiences with Professional-C Serums: 

“Obagi Professional-C Serum has worked a miracle. Using this product and having regular facials I have much smoother and cleaner skin. Dead skin cells exfoliated has allowed removal of hardened sebaceous oil, which had clogged pores. Obagi-C has allowed my skin to glow again. I am asked on a daily basis if I received a facial today. This is a fabulous product and I am interested in the complete line.”
