Obagi vs. SkinCeuticals vitamin C-Which is the better vitamin C serum?

Settling on the perfect anti-aging serum does take time considering the number of products in the market. Comparing super brands like Obagi vs. SkinCeuticals vitamin C are one of the tasks I performed when searching for the best serum to use.

I love my job as a lifeguard, I get to work on the beach of all places, and I get to effortlessly work on my tan-which in retrospect I may have overindulged. So there I was, 27 years of age with uneven toned sun damaged skin and I was devastated. I started trying different vitamin c serums in the market, and that’s when I happily settled on the two brands as mentioned above. This Obagi vs. SkinCeuticals vitamin C comparison review will highlight why these two products stand out.

Here are some differences between Obagi and SkinCeuticals vitamin C

Obagi vs. SkinCeuticals vitamin C- How do the two compare?


Obagi vitamin C is made up of vitamin E and signal lock complex extracts from artichoke leaves. This blend works to heal and hydrate the skin leaving it nourished and protected throughout the day. SkinCeuticals vitamin C, in contrast, contains vitamin E and Ferulic acid which neutralizes free radicals and increases absorption and potency of the serum respectively.


The trick to avoiding skin irritation is to find a serum with the perfect pH level. It can’t be too alkaline or acidic. Obagi C has a pH level of 3.5 while SkinCeuticals vitamin C has a pH level of 2.5. A lower pH signifies higher vitamin C concentration which ultimately promotes collagen production that results in healthier looking skin.

The Obagi C, however, comes in different vitamin C concentrations with C20 being the highest and strongest, which is beneficial when you want to break into using vitamin C serums slowly.


Both these products are oil-free and non-comedogenic which goes a long way in protecting you from pesky breakouts. It brightens dark and sun spots, smooths wrinkles and fine lines and does wonders in giving you a more natural youthful look. These serums have antioxidant properties that neutralize free radicals which are responsible for premature aging.

Regular and continuous use of these products visibly improve the elasticity of your skin.

Frequently Asked Questions

Can I use the Obagi C20 serum?

The Obagi C series has different concentrations of vitamin C. C20 is the highest concentration and is used to tackle advanced skin issues. It is preferable that you start with the lowest concentration (C5) and move upwards once your skin has acclimated.

How do I use vitamin C serums?

Vitamin C serums are used after cleansing and or toning. Once this is done, dry the area and apply 3-4 drops on your hand and rub it onto the desired area. You can then proceed to apply your makeup or sunscreen and seize the day.

I have sensitive skin, can I use vitamin C serum?

Yes, just be sure to check the pH levels indicated on the bottle and make sure your brand is not too acidic. In case you start to feel a burning sensation that won’t go away stop using the product immediately.

Are these products oil free?

Yes, both Obagi C and SkinCeuticals vitamin C are oil free. They may feel oily during the application, and this will be due to ingredients that help vitamin C to be readily absorbed in the skin. Once the serum has been absorbed your skin will not feel caked or oily.

Is SkinCeuticals vitamin C alcohol-free?

SkinCeuticals vitamin C is not, and if you have any reservations against using alcohol-based products this may not be the product for you. It is, however, paraben free which is more important since parabens are known to cause cancerous tumors.
