Obagi Professional-C Serum 20% is a concentrated serum with 20% vitamin C that provides multiple benefits for the complexion. This ingredient neutralises free radicals that break down collagen and elastin causing damage and leading to fine lines, wrinkles and dark spots. It also promotes collagen production which helps plump the skin and reduce the look of wrinkles.

This formula absorbs quickly without leaving the complexion greasy or oily. The 20% L-ascorbic acid promotes an even tone and texture. Its advanced form of vitamin C absorbs five times more easily than other serums. 

Who's it for?

Suitable for normal and oily skin types.

  1. Cleanse skin.
  2. Daily in the morning, apply 5 to 7 drops of the serum to the face, neck and chest using fingertips. 

Tip: Follow with an Obagi sunscreen.
