This physician-endorsed serum delivers a high-performance dose of pure vitamin C (L-ascorbic acid) formulated at optimized pH for stability and skin penetration.

Lightweight and fast-absorbing, the 0.42 oz bottle is made for daily application when seeking brighter, more even-looking skin.

How does this serum help improve dull or uneven skin tone?

The serum uses 15% L-ascorbic acid, a form of vitamin C shown to target surface discoloration and enhance skin luminosity. Regular morning use can support a more even-looking complexion when paired with sun protection.

• 15% concentration targets visible dullness and uneven tone
• Formulated at a pH that promotes ingredient stability and absorption
• Lightweight texture layers under moisturizers and SPF

Will this reduce the appearance of fine lines and wrinkles?

Vitamin C is a powerful antioxidant that helps neutralize free radicals which contribute to visible signs of aging. When used consistently, the formula can help the skin appear smoother and more refined alongside a full skincare regimen.

• Antioxidant support helps defend against environmental stressors
• Regular application supports a smoother-looking skin surface
• Pairs with nighttime retinol for more comprehensive results

How should I incorporate Obagi Medical Professional-C 15% into my daily routine?

Apply a few drops to clean, dry skin each morning before moisturizer and sunscreen. For best practice, use vitamin C in the daytime and reserve retinol for evening to follow Obagi’s recommended ABCs of skincare.

• Use 1–2 drops on face and neck after cleansing in the morning
• Allow absorption before applying moisturizer and broad-spectrum SPF
• Avoid mixing directly with strong acids or benzoyl peroxide in the same step

Is this serum suitable for all skin types and tones?

Obagi Medical formulates this professional-strength vitamin C to be effective across skin types and tones; however, those with sensitive skin should patch-test and introduce the product gradually. Dermatologist-tested and physician-endorsed, it’s created for clinical-level results at home.

• Dermatologist-tested formulation intended for broad skin compatibility
• Start with alternate-day use if skin is reactive, then increase frequency
• Pairs well with sunscreen and night-time retinoids for balanced care

Who is this for: Obagi Medical Professional-C 15% Vitamin C Serum is aimed at anyone seeking a high-strength antioxidant serum to brighten the complexion and reduce the visible appearance of fine lines. It’s a good fit for users who already follow basic skincare steps—cleanse, treat, protect—and want a clinically respected vitamin C option that integrates into morning routines under sunscreen. If you have highly reactive skin, consult a skincare professional and patch-test before regular use.
