FAQ

Is this product oil-free and non-comedogenic?

Yes! Obagi Professional C-Serum 20% is oil-free and non-comedogenic.

If I have very dry or sensitive skin, which Professional C Serum should I use?

Vitamin C can cause a slight irritation or excess dryness if you have never used it before or have a sensitive skin type. For dry skin types, we recommend beginning with Obagi Professional-C Serum 10% and gradually increasing to the Obagi Professional C-Serum 15% and 20% options as your skin grows more accustomed to this powerful ingredient.

Is this serum hydroquinone-free?

Yes! This serum is completely free of hydroquinone.

How long does this serum stay potent?

Vitamin C serums like this one have a two-year shelf life unopened, and once you open it you should use the product within 6-9 months to receive optimal benefits.

How would I incorporate this into my Obagi Nu-Derm routine? AM or PM?

When introducing Obagi Professional-C Serum 20% into your Obagi Nu-Derm routine, we suggest applying it as the first treatment step in your routine both morning and night, right after cleansing and toning your skin. You can then follow with Obagi Nu-Derm Clear FX #3 and the rest of your NuDerm FX regimen.

The serum in my newly purchased bottle has a light yellow color. Is this normal or has the product oxidized?

Obagi Professional-C Serum 20% can range in color from clear to straw yellow. Once the serum is opened, it gradually turns to darker yellow or orange color over time. This change in color does not affect the product's efficacy. For best results, you should store your Obagi Professional-C Serum at room temperature and away from direct sunlight.

Is this serum part of a line of Obagi products?

Yes! Obagi has crafted an entire line of Professional-C products that are designed to complement and work with another for glowing, youthful skin. From dry skin to oily skin, our professional products do it all.

What is the difference between lightening and brightening?

Lightening creams work to reduce the melanin pigmentation in a particular area on the skin and are best used for a limited amount of time. Brightening is more about increasing radiance and restoring natural vibrancy to dull or aging skin. Skin brightening products, like Obagi’s Professional-C Serum, are designed to remove dead skin cells to reveal radiant, glowing skin.

Is Obagi good for wrinkles?

Yes! Many of our professional products, including our facial serums like the Professional C-Serum, are designed to address the signs of aging to reveal a more youthful appearance.

Why does Vitamin C tingle my face?

Vitamin C is generally well-tolerated by most skin types, but if you have sensitive skin, it might sting or burn a little bit—especially if you use it in the same part of your routine as exfoliating scrubs or acids, like benzoyl peroxide. If you experience any burning sensations, start with Obagi’s Professional C-Serum 10% every other day, and work your way up to the more potent products as your skin becomes used to it.

What does Obagi Professional-C Serum do?

This professional-grade facial serum is a concentrated anti-aging serum enriched with vitamin C and a combination of moisturizing ingredients to provide rich moisture, enhance brightness, even skin tone, and reduce the signs of aging.

Which Obagi Professional-C Serum should I use?

Your skin type will help determine what kind of Obagi C Serum you should use. If you have dry skin or sensitive skin, start with the Obagi Professional-C Serum 10% until you know how the product will affect you. If you have normal skin, combination skin, or oily skin, feel free to start with either the 15% or 20% to give you the look you desire.
