Obagi Professional-C 10% Serum 30ml

Obagi Professional-C 10% Serum delivers L-ascorbic acid at a concentration appropriate for patients with sensitive skin or those new to topical vitamin C. L-ascorbic acid is the biologically active form of vitamin C and the most extensively studied topical antioxidant — at 10%, it provides meaningful photoprotective and brightening benefits while remaining within the tolerance threshold of reactive or sensitised complexions. It functions as both a standalone antioxidant and as a preparatory step before advancing to higher concentrations.

What it does:

• Delivers 10% L-ascorbic acid in a stable, low-pH vehicle — providing antioxidant defence against UV-induced free radical damage when used alongside SPF
• Supports collagen synthesis through fibroblast stimulation, contributing to firmer, more resilient skin over consistent long-term use
• Inhibits tyrosinase activity, reducing melanin overproduction and gradually improving uneven skin tone and post-inflammatory discolouration
• Entry-level concentration minimises the tingling and transient erythema that higher-strength vitamin C can provoke in sensitised or reactive skin

Best for: Patients with sensitive, reactive, or rosacea-prone skin who are introducing topical vitamin C for the first time, or those building toward higher-concentration formulations.
