Obagi Medical Professional-C Serum 15% Vitamin C, 1 fl oz — Brightening Antioxidant for Radiant Skin

Obagi Medical Professional-C Serum 15% is a high-concentration L-ascorbic acid serum formulated to brighten skin tone, defend against daily oxidative stress, and help reduce the visible signs of aging.

This professional-grade vitamin C serum delivers a potent, pH-optimized form of L-ascorbic acid to the skin in a stable formula designed for everyday morning use. Created by Obagi Medical, the formula focuses on antioxidant protection and visible radiance, pairing well with sunscreen and evening retinol routines. The lightweight serum is intended for use on all skin types and aims to support a smoother, more luminous complexion when used consistently.

How does this serum improve skin brightness and texture?

The 15% L-ascorbic acid concentration works as a strong antioxidant to help even skin tone and improve overall radiance when applied regularly. It can support the skin’s appearance by targeting dullness and helping protect against environmental free radicals that accelerate visible aging.

• Contains 15% pure L-ascorbic acid for brightening and antioxidant support
• Formulated at a pH level that optimizes vitamin C stability and absorption
• Lightweight, fast-absorbing serum suitable for layering under sunscreen

How should I incorporate Obagi Professional-C Serum into my routine?

Use the serum in your morning regimen after cleansing and before sunscreen to maximize antioxidant protection throughout the day. For best results, follow Obagi’s recommended ABCs of skincare: vitamin C in the AM, retinol (vitamin A) in the PM, and a broad-spectrum sunscreen during daylight.

• Apply a few drops to clean, dry skin each morning
• Allow it to absorb fully before applying moisturizer and SPF
• Pair with evening retinol for a complementary day–night regimen

Is this serum suitable for sensitive or all skin tones?

Obagi Medical designs products to be effective across a range of skin types and tones, with dermatologist testing and clinician endorsement. If you have highly reactive or very sensitive skin, introduce the serum gradually and consider patch testing to gauge tolerance before daily use.

• Dermatologist-tested, physician-endorsed formulation
• Suitable for many skin types when introduced progressively
• Patch test on a small area if you have a history of sensitivity

What results can I expect and how soon?

With consistent application, many users notice improvements in skin radiance and a more even tone over weeks to months. Visible softening of fine lines and an overall healthier-looking complexion may develop with continued use alongside sun protection and supportive products.

• Initial brightness often noticed within weeks of regular use
• Continued improvements in tone and texture with ongoing application
• Best outcomes when combined with daily SPF and a complementary night regimen

Who is this for: Obagi Medical Professional-C Serum 15% is designed for adults seeking a clinically minded antioxidant serum to boost brightness, support the skin’s defenses against environmental stressors, and help refine the look of uneven tone and early signs of aging. It suits those who want a potent morning antioxidant step that pairs with sunscreen and an evening retinol routine. If you have concerns about sensitivity, start slowly and consult a skincare professional for personalized guidance.
