Does Obagi Obagi-C Fx System C-Clarifying Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Obagi Obagi-C Fx System C-Clarifying Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.0 out of 10.
  • Some anti-wrinkle efficacy: Obagi Obagi-C Fx System C-Clarifying Serum has an anti-wrinkle rating of 2.5 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, Obagi Obagi-C Fx System C-Clarifying Serum is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, entirely due to the high content of Propylene Glycol (est. ≈10.3%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Some anti-wrinkle efficacy

According to CreamScan analysis, Obagi Obagi-C Fx System C-Clarifying Serum has a slight anti-wrinkle rating of 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈10.0%), 
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Rich in skin-protecting antioxidants

We estimate that Obagi Obagi-C Fx System C-Clarifying Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈10.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Propylene Glycol
Est. %10.3
Function
Origin
Propylene GlycolA clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.

Ascorbic Acid
Est. %10
Function
Origin
Ascorbic Acid

Also known as vitamin C, this multi-benefit ingredient has proven anti-wrinkle, antioxidant, and anti-pigmentation efficacy. It degrades easily when exposed to air and light, so it requires proper packaging to maintain its stability.

Arbutin
Est. %1.5
Function

ArbutinOne of the few potent anti-pigment compounds found naturally in bearberry or cranberry leaves. When applied to the skin, this ingredient converts into hydroquinone, with tyrosinase inhibiting effects.
Propylene Carbonate
Est. %1.3
Function
Origin
Propylene CarbonateA derivative of propylene glycol that is used most frequently as a solvent. Additionally, propylene carbonate serves as a viscosity controlling agent reducing the thickness of the products it is added to.
