Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.2 out of 10 and a high humectancy of 6.6 out of 10, primarily due to the high content of Arginine (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Obagi Obagi-C Rx System C-Exfoliating Day Lotion has a minimal anti-wrinkle rating of 1.5 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Glycolic Acid (est. ≈9.0%),
highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
Among others, Obagi Obagi-C Rx System C-Exfoliating Day Lotion also contains Ascorbyl Glucoside, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Ascorbyl Glucoside provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.

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

Ingredients explained

Water
Est. %65
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.
Glycolic Acid
Est. %9
Function
Origin

The second most used AHA (after lactic acid) known for its potent exfoliating and smoothing effects. It increases skin cell turnover, which is beneficial for treating acne. When used in peels, glycolic acid has confirmed anti-wrinkle efficacy, though it is less effective in leave-on products like creams and serums.

Arginine
Est. %6
Function
Origin
A humectant amino acid used to attract water to the skin’s surface. It is a part of the skin's Natural Moisturizing Factor, a mixture of various compounds that keeps the skin’s surface well hydrated. Arginine can also be used as a pH adjuster.
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
Est. %3
Function
Origin
An emulsion stabilizer and thickener that helps to create a pleasant, satiny, and light formula texture. It works by forming a gel-like network within water or oil, which both stabilizes other ingredients and produces a thickening effect.
Squalane
Est. %2.9
Function
Origin
An occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Polysorbate 60
Est. %2.5
Function
Origin
An ester based on sorbitan. It is good for emulsifying water and oils together – specifically making oil-in-water emulsions. Polysorbate 60 is also said to give a product a notable fragrance.
Ethylhexyl Palmitate
Est. %2
Function
Origin
A rich emollient without the oily after-feel, making it a popular replacement for mineral oil. It is derived from natural sources such as palm oil and palm kernel oil. Ethylhexyl palmitate is listed as a common comedogenic ingredient by acne.org.
Ethylhexyl Stearate
Est. %1.5
Function
Origin
A palm-derived emollient ester with good lubricity that leaves a smooth after-feel on the skin.
Caprylic/Capric Triglyceride
Est. %1.3
Function
Origin
A natural occlusive moisturizing and emollient ingredient, it is a blend of glycerin and two fatty acids, caprylic and capric acid. It creates an oil-based protective layer on the skin, thereby preventing water loss.
Isopropyl Palmitate
Est. %1
Function
Origin
An emollient ester of palmitic acid and isopropanol that gives the skin a smooth, soft, dry, non-oily after-feel. Isopropyl palmitate is listed as a common comedogenic ingredient by acne.org.
Glyceryl Stearate
Est. %0.3
Function
Origin
An emollient and emulsifier typically derived from vegetable sources through a chemical reaction with glycerin. It provides stability, texture, and consistency to formulations. Its main function is to allow oil and water to mix.
PEG-100 Stearate
Est. %0.3
Function
Origin
This surfactant is more specifically classified as an emulsifier that produces oil-in-water emulsions. PEG-100 stearate can also be used as a cleansing agent.

Function
Origin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Ascorbyl Glucoside
Est. %0.3
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.
Sodium Hyaluronate
Est. %0.3
Function
Origin
A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.
Tocopheryl Acetate
Est. %0.3
Function
Origin
An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.
Phenoxyethanol
Est. %0.3
Function
Origin
The most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Cetearyl Alcohol
Est. %0.3
Function
Origin
A blend of cetyl alcohol and stearyl alcohol, the fatty alcohols that are derived from palm oil. It helps to create emulsions that give off a soft and silky emollient feel and also increase product thickness.
Ceteareth-20
Est. %0.3
Function
Origin
A fatty alcohol emulsifier that helps to mix oil and water together, best for oil-in-water emulsions. It is also a cleansing agent. When combined with cetearyl alcohol, ceteareth-20 forms a mix that, according to acne.org, can be comedogenic.
Dimethicone
Est. %0.3
Function
Origin

Est. %0.3
Function
Origin
A waxy, naturally derived or synthetic emulsifier that can handle extreme formula conditions such as a low pH. It offers emulsifying properties to a formula by helping oils and water to mix.
Tetrasodium EDTA
Est. %0.3
Function
