Does SkinBetter Science Solo Hydrating Defense Men work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using SkinBetter Science Solo Hydrating Defense Men:

  • Significant moisturizing. It has a moisturizing rating of 6.7 out of 10.
  • Little anti-wrinkle effect: SkinBetter Science Solo Hydrating Defense Men has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Highly moisturizing: SkinBetter Science Solo Hydrating Defense Men has a moisturizing rating of 6.7 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Butylene Glycol (est. ≈9.0%) and Glycerin (est. ≈2.5%), and a moderate occlusivity of 3.4 out of 10, mainly due to the high content of Caprylic/Capric Triglyceride (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, SkinBetter Science Solo Hydrating Defense Men has a minimal anti-wrinkle rating of 0.4 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Ectoin (est. ≈0.3%),
 an amino acid-derived ingredient with average, yet proven by one study, anti-wrinkle efficacy.
 
Among others, SkinBetter Science Solo Hydrating Defense Men also contains some ingredients marketed as effective in reducing wrinkles, specifically Aminopropyl Ascorbyl Phosphate, Camellia Sinensis Leaf Extract, Olea Europaea (Olive) Fruit Extract, and Ubiquinone. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver additional anti-wrinkle efficacy through its moisturizing action.
 

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

Antioxidant benefits

We estimate that SkinBetter Science Solo Hydrating Defense Men is rich (> 3%) in antioxidants, specifically Chlorogenic Acids (est. ≈1.3%), Hydrolyzed Sodium Hyaluronate (est. ≈1.0%), Glycyrrhiza Glabra (Licorice) Root Extract (est. ≈0.3%), and others.

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.

Ingredients explained

Water
Est. %55
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.
Butylene Glycol
