Meet Obagi Medical Professional-C 20% Serum

This highest‑concentration Vitamin C serum from Obagi is designed to help brighten skin tone and reduce the appearance of fine lines. Powered by L‑ascorbic acid—the purest form of vitamin C—the formula is crafted for professional‑grade skincare, packaged in a dark bottle to help preserve potency, and delivered in a convenient 1 oz size.

Key features and values you may notice in everyday use include a focus on stability, absorption, and skin resilience. The product is backed by professional oversight and a long history of scientific testing, aligning with Obagi’s commitment to medical‑grade skincare for diverse skin tones and types.

What makes this serum stand out:

• Highly concentrated L-ascorbic acid with a pH tuned to support stability, permeability, and efficacy in neutralizing free radicals.
• Stable, lightweight formula that absorbs with minimal residue, helping to fortify the skin barrier over time.
• Clinical insight includes data on file indicating a majority of users reported brighter and more hydrated looking skin after use.
• Dermatologist-tested, physician-endorsed—a hallmark of Obagi’s medical‑grade skincare approach.

Designed for professional guidance and everyday routines alike, this serum reflects Obagi’s 35 years of skincare expertise. It comes in packaging that protects potency and fits seamlessly into a mornings or evenings regimen.

Use and routine considerations:

• Apply a pea‑sized amount to clean, dry skin once daily or as directed, avoiding the immediate eye area.
• Follow with a moisturizer and, during daytime use, a broad‑spectrum sunscreen to protect treated skin.

What you may experience over time is a more even complexion and a hydrated, supple appearance, with the option to adjust usage as part of a personalized skincare plan. Obagi emphasizes professional backing and reliable formulations to support diverse skincare journeys.

Packaging and longevity note: the serum is housed in a protective dark glass bottle to help preserve potency, with a 1 oz (30 ml) size designed for ongoing use as part of a skincare routine. With proper storage and consistent use, it aligns with a long‑standing tradition of medical‑grade skincare solutions from Obagi.
