Key Benefits of Obagi Vitamin C + Arbutin Brightening Serum

 
These are the key benefits you can expect from using Obagi Vitamin C + Arbutin Brightening Serum:
 

🔵 Lightweight Purely Humectant Moisturizer Well-Suited for Oily Skin

According to CreamScan analysis, Obagi Vitamin C + Arbutin Brightening Serum is lightly moisturizing, with a moisturizing rating of 3.0 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a high humectancy of 6.0 out of 10, entirely due to the high content of Propylene Glycol (est. ≈6.0%).

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

📌 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.

💧 A Humectant Enhancement for Any Skincare Routine

But it’s not limited to oily skin - such a humectant enhancement 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.

🟣 Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Obagi Vitamin C + Arbutin Brightening Serum has a slight anti-wrinkle rating of 1.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈2.0%),
 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 additional anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Obagi Vitamin C + Arbutin Brightening Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈2.0%).

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.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Obagi Vitamin C + Arbutin Brightening Serum

 
CreamScan identified a few things to consider before adding Obagi Vitamin C + Arbutin Brightening Serum to your skincare routine:
 

⚠️ If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Obagi Vitamin C + Arbutin Brightening Serum as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

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.
Alcohol Denat.
Est. %4
Function
Origin
Alcohol Denat.

Denatured alcohol is ethanol that contains additives that make it unsafe to consume. It is mainly used as a solvent and an antimicrobial agent. A major drawback to alcohol denat. is that it dries out the skin.

Dipropylene Glycol
Est. %3

Origin
Dipropylene GlycolA clear, colorless liquid that has several uses. One of its main functions is as a solvent. Dipropylene glycol is also used to reduce the thickness of skincare products.
Ascorbic Acid
Est. %2
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

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.
Sodium Lauryl Sulfate
