Does La Roche-Posay Effaclar Duo (+) Dual Action Acne Treatment work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using La Roche-Posay Effaclar Duo (+) Dual Action Acne Treatment:

  • Light moisturizing. It has a moisturizing rating of 2.5 out of 10.

Basic moisturizer for oily skin

According to CreamScan analysis, La Roche-Posay Effaclar Duo (+) Dual Action Acne Treatment is lightly moisturizing, with a moisturizing rating of 2.5 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 moderate humectancy of 5.0 out of 10, due to the high content of Glycerin (est. ≈3.0%) and Pentylene Glycol (est. ≈2.0%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula without any occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

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.

Since it contains a moderate amount of humectants, it can also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

Ingredients explained

Water
Est. %80
Function
Origin
WaterThe 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.
Benzoyl Peroxide
Est. %5.5
Function
Origin
Benzoyl Peroxide
Isostearyl Alcohol
Est. %4
Function
Origin
Isostearyl Alcohol
Glycerin
Est. %3
Function
Origin

Pentylene Glycol
Est. %2
Function
Origin
Pentylene Glycol

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Silica
Est. %1.5
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Carbomer
Est. %1.3
Function
Origin
CarbomerA synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Capryloyl Salicylic Acid
Est. %0.3
Function
Origin
Capryloyl Salicylic AcidA derivative of salicylic acid, with bigger and more lipid-soluble molecules. This makes it more powerful and safer than salicylic acid. It is used as an exfoliating and peeling agent.
Potassium Hydroxide
Est. %0.3
Function
Origin
Potassium HydroxideA very alkaline ingredient, meaning that it has a high pH. Potassium hydroxide is therefore useful in bringing a low pH in a cosmetic product up to a more neutral, skin-safe level.
Tocopheryl Acetate
Est. %0.3
Function
Origin
Tocopheryl Acetate

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.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer
Est. %0.3
Function
Origin
Acrylates/C10-30 Alkyl Acrylate CrosspolymerA synthetic ingredient that is used to thicken water and alcohol. It results in a more lightweight formula and is commonly found in gel products.
Disodium EDTA
Est. %0.3
Function
Origin
Disodium EDTAA synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Epilobium Angustifolium Flower/Leaf/Stem Extract
Est. %0.3
Function
