PRODUCT OVERVIEW Obagi Professional-C Serum 10% is a high-performance antioxidant facial serum formulated with 10% L-Ascorbic Acid, the pure form of vitamin C. It is designed for dry or sensitive skin that wants visible brightening and antioxidant protection without unnecessary irritation. The lightweight texture absorbs rapidly so it layers cleanly under moisturizer and sunscreen. Regular morning use helps support a brighter, more even-looking complexion while improving the appearance of fine lines and wrinkles. This serum fits a simple morning routine: cleanse, tone if desired, apply the serum, follow with moisturizer, and finish with broad-spectrum SPF. At 10% it offers a milder entry point into the Professional-C line, making it a practical choice for those new to vitamin C or with more reactive skin. KEY FEATURES 10% L-Ascorbic Acid, a gentler concentration suited to dry or sensitive skin. Lightweight, fast-absorbing serum texture. Minimalist formula focused on pure vitamin C delivery. Oil-free and designed to avoid heavy residue. Glass bottle with precision dropper for controlled application. Available in 1 fl oz and 0.42 fl oz sizes. Formulated for dry to sensitive and normal-to-dry skin types. Designed for consistent morning application as part of an antioxidant routine. HOW IT WORKS L-Ascorbic Acid is the pure, active form of vitamin C. At 10%, it helps neutralize free radicals that contribute to a dull, uneven skin tone. The formula supports a brighter, more even complexion and can improve the appearance of fine lines and wrinkles with regular use, while remaining milder than higher concentrations. The serum absorbs quickly into the skin so the active ingredients remain available. Antioxidant support works best when paired with daily broad-spectrum sunscreen. Always apply SPF after the serum and moisturizer in the morning. WHO IT'S FOR This serum is intended for adults with dry or sensitive skin who want a gentle daily vitamin C treatment. It suits people concerned with the appearance of uneven tone, dullness, or early fine lines and who prefer a lower-strength option. It is often a good starting point for those new to vitamin C or who find higher concentrations too intense. Normal to combination skin can also use it if a milder formula is preferred. Patch testing is recommended. This product is for external cosmetic use only and is not a treatment for medical skin conditions. WHY CHOOSE THIS PRODUCT Obagi Professional-C Serum 10% offers a lower concentration of pure L-Ascorbic Acid that prioritizes comfort for dry or sensitive skin. The formula is lightweight and absorbs quickly, making it easy to layer under daytime products. It provides the same core brightening and antioxidant benefits as higher strengths in the Professional-C line, but with reduced intensity. Clear usage instructions and consistent packaging with a precision dropper keep daily application simple. Customers looking for a professional-grade vitamin C serum that is gentle enough for reactive skin will find this option practical and focused.
