Product Overview

Obagi Professional-C Serum 15% is a high-performance antioxidant serum built on 15% L-Ascorbic Acid — the pure form of vitamin C. It's made for normal to combination skin looking for visible brightening along with stronger protection against everyday environmental stress.

The lightweight texture absorbs fast, so it layers cleanly under moisturizer and sunscreen. With regular morning use, it helps support a brighter, more even-looking complexion while softening the appearance of fine lines and wrinkles.

It fits neatly into a simple morning routine: cleanse, tone if you like, apply the serum, follow with moisturizer, then finish with broad-spectrum SPF. At 15%, it strikes a balance many people find effective for daily use, without the higher intensity of the 20% version.
