Obagi Professional-C 20% Brightening Kit pairs a 30ml full-size and a 12.5ml travel-size bottle of the brand's strongest vitamin C serum, with 20% L-ascorbic acid and sodium hyaluronate, developed by dermatologists for normal to oily or combination skin that wants to look brighter.

What it does

The kit contains one 30ml and one 12.5ml bottle of Professional-C Serum 20%, one for the shelf and one for the travel bag. The formula is a lightweight, fast-absorbing serum with 20% L-ascorbic acid, the highest concentration in the Professional-C range, for antioxidant support against everyday environmental stressors and a visibly brighter, more even-looking complexion. Sodium hyaluronate draws in moisture so skin feels hydrated and comfortable rather than tight, and the texture sits cleanly under moisturiser, SPF and makeup. With daily morning use skin looks more luminous and less dull. A slight tingle on application is normal at this strength.

How to use

Each morning after cleansing and toning, apply five to seven drops to the face and neck, then moisturiser and sunscreen. Keep the bottle tightly closed and use within three to six months of opening. Patch-test first.

Who it's for

Normal to oily or combination skin that already tolerates vitamin C and wants the brand's top strength, with a travel size for weekends, work trips or the gym bag.
