Obagi Medical Professional-C Vitamin C Serum 15% (0.42 oz) — Brightens Skin & Helps Smooth Fine Lines

This professional-grade serum combines a 15% concentration of pure vitamin C (L‑ascorbic acid) in a pH‑balanced formula optimized for stability and skin penetration. It’s formulated for use in a morning regimen to support skin radiance, help defend against environmental free radicals, and complement evening retinoid use and daily broad‑spectrum sunscreen.

How quickly will I notice brighter skin?

Results vary by individual, but many users observe improved skin luminosity and a fresher tone within several weeks of consistent morning use. The product is formulated to deliver vitamin C in an active, absorbable form to help address uneven tone from daily environmental exposure.

• Contains 15% L‑ascorbic acid for measurable antioxidant activity
• pH adjusted to support absorption and stability
• Daily use in the AM maximizes daytime protection with sunscreen

Can this serum help with fine lines and early signs of aging?

The serum is designed to minimize the appearance of fine lines by supporting skin’s resilience and improving surface texture. While not a replacement for professional procedures, regular application can make skin look smoother and more even over time.

• Targets visible signs of past skin damage and texture irregularities
• Supports the skin barrier to promote a firmer appearance
• Works synergistically with nighttime retinoids for a complete regimen

How should I use this vitamin C serum in my routine?

Apply a few drops to clean, dry skin each morning before moisturizer and sunscreen. Start slowly if you have sensitive skin, then increase to daily use as tolerated; avoid layering with unstable vitamin derivatives without professional guidance.

• Use mornings after cleansing and before moisturizer and sunscreen
• Introduce gradually if you have sensitivity—every other day to start
• Pair with a broad‑spectrum SPF as part of daytime protection

Is this suitable for all skin tones and types?

Obagi Medical formulates and tests products across a broad range of skin tones and types; this serum is intended for those seeking antioxidant protection and brighter skin. If you have very reactive skin, consult a skincare professional before starting a new active treatment.

• Dermatologist tested and used in clinical settings
• Formulated for stability across diverse skin types and tones
• Not a substitute for medical advice for sensitive skin conditions
