Obagi Medical 10% Professional-C Serum, 1 fl oz — Vitamin C L‑Ascorbic Acid for Brightening & Anti‑Aging

Obagi 10% Professional-C Serum is a lightweight, L‑ascorbic acid vitamin C serum formulated to brighten skin tone and help reduce the visible appearance of fine lines and wrinkles.

This physician-endorsed serum blends 10% pure L‑ascorbic acid at a pH designed for stability and skin absorption. It’s designed to be incorporated into a morning routine alongside sunscreen to support a more even, radiant complexion. Dermatologist-tested and backed by Obagi Medical’s decades of clinical experience, this formula focuses on delivering reliable antioxidant support in a cosmetically elegant base.

How does this vitamin C serum fit into a daily skincare routine?

Apply the serum in the morning after cleansing and before moisturizing and sunscreen. Vitamin C works best in the AM to provide antioxidant support during the day, complementing nightly active ingredients like retinol.

• Use 3–5 drops on cleansed skin, patting gently until absorbed.
• Follow with a hydrating moisturizer to lock in benefits.
• Always finish with a broad-spectrum sunscreen for daytime protection.

What results can I realistically expect and when?

Consistency matters: visible improvements in skin radiance and a more even tone typically develop over several weeks. You may notice immediate brightening and gradual softening of fine lines with continued use.

• Initial brightening often within 2–4 weeks for many users.
• Progressive improvement in texture and tone over 6–12 weeks.
• Maintain results by using daily with sunscreen and a balanced routine.

Is the formula suitable for sensitive or combination skin?

The serum contains 10% L‑ascorbic acid at pH levels selected for effectiveness; some users with sensitive skin may need to introduce it gradually. Patch testing and slowly increasing frequency can help your skin adapt.

• Perform a patch test behind the ear or on the inner wrist first.
• Start every other morning if irritation occurs, then increase to daily.
• If persistent irritation appears, discontinue and consult a skincare professional.

How should I store and use the product for best longevity?

L‑ascorbic acid formulas are sensitive to light and air; keep the bottle capped and stored in a cool, dark place. Using the product consistently but not exposing it to excessive heat or direct sunlight preserves potency.

• Store upright, tightly closed, away from direct sunlight.
• Use within the recommended period after opening to maintain effectiveness.
• Replace the dropper cap carefully to limit air contact after each use.

Who is this for? Obagi 10% Professional-C Serum is designed for adults looking to brighten dull skin, even tone, and address the visible signs of aging like fine lines. It suits those who prefer a clinically informed, physician-endorsed serum with a straightforward ingredient profile and who are committed to a morning routine that includes sunscreen. If you have very reactive skin, consider introducing the serum gradually or consult a skincare professional for personalized guidance.
