Obagi Medical Professional-C 15% Vitamin C Serum — 0.42 oz, Brightening Antioxidant for Fine Lines

Obagi Medical Professional-C 15% Vitamin C Serum is a concentrated L-ascorbic acid treatment designed to brighten skin tone and reduce the visible appearance of fine lines and wrinkles.

This concentrated daily serum from Obagi Medical uses 15% pure vitamin C (L-ascorbic acid) formulated at a skin-friendly pH to improve radiance and support skin resilience. It’s lightweight, fast-absorbing, and designed to fit into morning routines alongside sunscreen to help protect against environmental stressors that can dull complexion over time. Dermatologists and skincare professionals commonly recommend vitamin C serums as a foundational antioxidant step for brighter-looking skin.

How does this serum help my skin look brighter?

The 15% L-ascorbic acid in this formula works as an antioxidant to help even out skin tone and reduce the look of past discoloration. By supporting the skin’s natural defenses and promoting a more uniform surface appearance, it helps restore a fresher, more luminous look.

• Contains 15% pure L-ascorbic acid for effective antioxidant action
• pH-balanced for better stability and skin penetration
• Lightweight texture absorbs quickly without residue

Will it help with fine lines and texture?

Regular use can help minimize the visible appearance of fine lines by supporting surface smoothness and improving overall skin tone. It’s intended as part of a multi-step routine—pairing it with evening retinoids and daytime SPF supports broader improvement in texture and clarity.

• Targets visible signs of aging like mild fine lines
• Compatible with following sunscreen for daytime protection
• Complements retinol treatments used at night

How should I use the Professional-C 15% serum in my routine?

Apply a few drops to clean, dry skin in the morning before moisturizer and sunscreen. Because it’s an active vitamin C product, start gradually if you have sensitive skin—use every other day, then increase to daily as tolerated.

• Use in the morning after cleansing and before moisturizer
• Follow with broad-spectrum sunscreen during daytime use
• Begin slowly if you have reactive skin and monitor tolerance

Is this appropriate for all skin types and tones?

Obagi Medical formulates products to be clinically tested across skin types and tones; this serum is intended to be broadly tolerable. Those with very sensitive or compromised skin should patch-test first or consult a skincare professional for personalized guidance.

• Formulated to be effective across multiple skin tones
• Dermatologist tested and physician endorsed
• Patch-test recommended for sensitive or reactive skin

It’s suitable for people beginning a corrective skincare routine as well as those experienced with active ingredients, provided you introduce it gradually if you have sensitive skin.
