Product Overview

Obagi Professional-C Serum 10% is a high-performance antioxidant serum built on 10% L-Ascorbic Acid — the pure form of vitamin C. It's made for dry or sensitive skin looking for visible brightening and antioxidant protection without unnecessary irritation.

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 easily into a simple morning routine: cleanse, tone if you like, apply the serum, follow with moisturizer, then finish with broad-spectrum SPF. At 10%, it's the gentlest entry point into the Professional-C line, making it a practical pick for anyone new to vitamin C or with more reactive skin.

How It Works

L-Ascorbic Acid is vitamin C in its pure, active form. At 10%, it helps neutralize the free radicals behind a dull, uneven skin tone. With regular use, the formula supports a brighter, more even complexion and can soften the look of fine lines and wrinkles — all while staying milder than the higher concentrations.

The serum absorbs quickly, so the active ingredients stay available on skin. Antioxidant support works best alongside daily broad-spectrum sunscreen — always apply SPF after the serum and moisturizer each morning.

Who It's For

This serum is built for adults with dry or sensitive skin who want a gentle daily vitamin C treatment. It suits anyone dealing with uneven tone, dullness, or early fine lines, and who prefers a lower-strength option.

It's often a good starting point for anyone new to vitamin C, or for those who found higher concentrations too intense. Normal to combination skin can use it too, if a milder formula is what you're after. Patch testing is recommended before regular use. This product is for external, cosmetic use only and isn't intended to treat any medical skin condition.

Why Choose This Product

Obagi Professional-C Serum 10% offers a lower concentration of pure L-Ascorbic Acid that puts comfort first for dry or sensitive skin. The formula is lightweight and absorbs quickly, making it easy to layer under daytime products.

It delivers the same core brightening and antioxidant benefits as the stronger options in the Professional-C line, just at a gentler intensity. Clear usage guidance and consistent dropper packaging keep daily application simple. For anyone after a professional-grade vitamin C serum gentle enough for reactive skin, this is a practical, focused choice.
