Overview

How moisturizing is this?

Quite moisturizing. Obagi Professional-C Serum 15% has a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive?

Purely humectant. It has a maximum Humectancy of 10 out of 10 and zero Occlusivity (we didn't find any occlusives on the ingredient list).
Tip: Studies suggest that humectants alone do not moisturize the skin. We recommend applying a product with some occlusive ingredients after the use of this one.

What else is good about it?

 Obagi Professional-C Serum 15% is rich in antioxidants. One of the many benefits of antioxidant ingredients is that they are believed to reduce the oxidative stress caused by free radicals, thus preventing accelerated skin aging.

Ingredients explained

Propylene Glycol
Est. %47.5
Function
Origin
A 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.
Water
Est. %25.1
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Ascorbic Acid
Est. %15
Function
Origin
Also known as vitamin C, this extremely well-researched antioxidant is able to boost collagen production, prevent wrinkles, and treat pigmentation. It degrades easily when exposed to air and so requires careful packaging.
Alcohol
Est. %6.8
Function
Origin
An effective antimicrobial ingredient that kills bacteria, fungi, and even some viruses. It is also an excellent solvent and astringent. Alcohol helps to create lighter and less viscous products. It can, however, be dehydrating and skin-sensitizing.
Ascorbyl Glucoside
Est. %4.6
Function
Origin
A derivative of vitamin C. It is more stable and less irritating than ascorbic acid. There are unfortunately no clinical studies on ascorbyl glucoside’s anti-pigment or anti-acne efficacy alone.
Fragrance

Origin
Under trade secret law, manufacturers have the right not to disclose what exactly went into the fragrance and use the unspecific word Fragrance or Parfum instead. Many fragrances are highly allergenic.
