Obagi Brightening Duo: Professional-C Serum 20% Kit

The Obagi Professional-C 20% Brightening Duo pairs a full-size 30ml bottle of Professional-C Serum 20%, the highest strength in the range, with a 12.5ml travel size free, so your vitamin C comes with you wherever you go.
Professional-C Serum 20% is formulated with L-ascorbic acid and sodium hyaluronate. Used every morning, it helps brighten dull skin, even out tone and the look of dark spots, supports the skin's antioxidant defences, and improves the appearance of fine lines with consistent use.
The 20% strength is best for normal to oily skin and for people already used to vitamin C. If your skin is drier or more sensitive, the 15% Brightening Duo or the 10% strength in our Professional-C Serum listing may suit you better.
The kit costs the same as the full-size serum on its own, so the travel size is free.
Professional-C Serum is not a sunscreen. Daily use of a broad-spectrum, high-SPF sunscreen is recommended as part of any skincare routine.
42.5ml in total: 30ml full size and 12.5ml travel size.
