Obagi Medical PROFESSIONAL-C Serum 15% Vitamin C, 1 fl oz — Brightening Antioxidant for Fine Lines

Obagi Medical PROFESSIONAL-C Serum is a concentrated 15% L‑ascorbic acid vitamin C serum designed to brighten skin tone and visibly smooth the look of fine lines and wrinkles.

This lab‑formulated serum blends a stable concentration of pure vitamin C at skin‑friendly pH to help neutralize environmental free radicals and support the skin’s natural barrier. Intended for morning use as part of a daily regimen, it layers easily under broad‑spectrum sunscreen and pairs with evening retinol treatments to create a complementary two‑step antioxidant and renewal approach.

How does this serum improve dull or uneven skin tone?

The core ingredient, L‑ascorbic acid, is a well‑studied form of vitamin C that targets pigmentation and radiance. By delivering a 15% concentration in a formulation optimized for stability and absorption, the serum helps reduce the appearance of discoloration and promotes a more luminous complexion.

• 15% L‑ascorbic acid concentration for brightening.
• Formulated at pH levels that favor skin uptake of vitamin C.
• Daily morning use enhances overall skin radiance over time.

Will this serum help reduce the look of fine lines and wrinkles?

The serum is formulated to visibly improve the look of fine lines and texture by supporting the skin’s resilience and reducing oxidative stress from daily exposure. Consistent application as directed may lead to smoother‑looking skin when combined with a full skincare routine.

• Antioxidant action helps protect against environmental aging factors.
• Supports skin barrier defenses that influence texture appearance.
• Works synergistically with evening retinol for renewal.

How should I incorporate Obagi PROFESSIONAL‑C into my skincare routine?

Use the serum in the morning after cleansing and before moisturizer and sunscreen. For best results, pair with a retinol product at night and apply broad‑spectrum SPF during the day to protect gains in tone and texture.

• Apply 2–3 drops to face and neck each morning after cleansing.
• Follow with moisturizer and broad‑spectrum sunscreen (SPF).
• Use retinol or vitamin A products in evening routines, not simultaneously with vitamin C at night.
