Obagi Medical Professional-C 10% Vitamin C Serum, 0.42 oz — Stabilized L‑Ascorbic Acid for Brightening & Hydration

Obagi Professional-C 10% Vitamin C Serum is a lightweight, fast-absorbing vitamin C treatment formulated to brighten skin tone, support moisture retention, and help reduce the visible appearance of fine lines and wrinkles.

This concentrated 0.42 oz serum delivers stabilized L-ascorbic acid at a 10% concentration in a formulation designed for normal to oily and sensitive-prone skin. It absorbs quickly without heavy residue, making it easy to layer under moisturizers and sunscreen. The formula emphasizes brightening and antioxidant support while helping skin feel soothed and hydrated for a refreshed look.

How will this serum affect my skin’s brightness and tone?

The 10% vitamin C (L-ascorbic acid) concentration works to even visible skin tone and enhance radiance with regular use. Results are gradual and accumulate over weeks as surface discoloration and dullness appear less noticeable.

• Contains stabilized L-ascorbic acid for antioxidant brightening
• Lightweight texture promotes rapid absorption
• Formulated to target visible dullness and uneven tone

Will this serum hydrate or irritate sensitive skin?

Obagi Professional-C 10% is formulated to balance brightening with skin comfort; it includes soothing ingredients to minimize irritation potential. For very sensitive or reactive skin, introduce slowly—every other day—and monitor skin response.

• Designed to be gentle on normal to oily and sensitive-prone skin
• Hydrating components help retain moisture and reduce dryness
• Patch-test recommended before daily use

How should I incorporate this serum into my daily routine?

Use the serum once or twice daily after cleansing and before moisturizer and SPF. Apply a few drops to face and neck, gently pressing in; follow with a daily moisturizer and broad-spectrum sunscreen in the morning.

• Apply to clean, dry skin—morning and/or evening
• Follow with moisturizer; always use SPF during daytime use
• Start gradually if new to vitamin C serums to assess tolerance

What visible changes can I expect and when?

Initial improvements in skin hydration and a slight boost in radiance can be noticed within days, while reductions in the appearance of fine lines and uneven tone typically develop over several weeks of consistent use. Individual results vary by skin type and regimen.

• Faster-feeling smoothness and renewed glow within days
• More even tone and diminished fine-line appearance over weeks
• Best outcomes with consistent nightly or twice-daily use and sun protection
