Obagi Medical Vitamin C Serum 15% (0.42 oz) — Brightening L‑Ascorbic Acid to Reduce Fine Lines

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

Formulated for daytime use, this 0.42 oz serum uses a 15% concentration of pure vitamin C (L-ascorbic acid) at a pH designed to support stability and skin penetration. It fits into a morning routine alongside broad-spectrum sunscreen and pairs well with evening retinoids. The product is part of Obagi Medical’s professional line, developed and tested with dermatology standards in mind.

How does this vitamin C serum improve skin brightness?

The L-ascorbic acid in this serum works as an antioxidant to address dullness and uneven tone. Regular application can help the skin appear more radiant while helping to even out areas of discoloration. Results depend on consistent use and proper complementary sun protection.

• Contains 15% L-ascorbic acid for pigment-targeted activity
• Formulated at low pH to optimize stability and skin absorption
• Lightweight serum texture that layers under sunscreen and makeup

Will it help minimize the look of fine lines and wrinkles?

Vitamin C supports the skin’s surface appearance by neutralizing free radicals that can accelerate visible aging. Over time, daily application may make fine lines appear smoother and skin tone look more uniform. Pairing with a nighttime retinoid can support a fuller approach to visible texture concerns.

• Antioxidant action targets environmental stressors
• Supports surface texture when used consistently
• Works best as part of a morning routine with sunscreen

How should I use this serum in my skincare routine?

Apply a few drops to cleansed, dry skin each morning before moisturizer and sunscreen. Allow the serum to absorb fully, then follow with a broad-spectrum SPF. If you use retinol at night, maintain the vitamin C as your daytime antioxidant step for complementary benefits.

• Use 1–3 drops daily in the AM after cleansing
• Follow with moisturizer and broad-spectrum sunscreen
• If new to vitamin C, introduce gradually to monitor tolerance

Is this product suitable for my skin type?

The formulation was tested across a range of skin types and tones to promote suitability for many users. Those with sensitive skin should patch-test first and introduce vitamin C slowly. If irritation occurs, discontinue and consult a skincare professional.

• Dermatologist-tested formulation from a medical-grade brand
• Recommended to patch-test sensitive or reactive skin
• Best combined with sunscreen for daytime protection
