Review

Results you may expect from using Rejuvi a Retinyl Serum:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Rejuvi a Retinyl Serum:

  • Intense moisturizing. It has a moisturizing rating of 10.0 out of 10.
  • Some anti-wrinkle efficacy: Rejuvi a Retinyl Serum has an anti-wrinkle rating of 2.5 out of 10 so you may expect some, although limited, effect on wrinkles.

How moisturizing is it?

Maximum hydration: Rejuvi a Retinyl Serum has the highest possible moisturizing rating of 10.0 out of 10.

Is it more humectant or occlusive? This is one of the most moisturizing products on the market, with a maximum humectancy of 10 out of 10, entirely due to the substantial concentration of Propylene Glycol (est. ≈22.0%), and a maximum occlusivity of 10 out of 10, primarily due to the significant content of Persea Gratissima (Avocado) Oil (est. ≈55.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Rejuvi a Retinyl Serum has a slight anti-wrinkle rating of 2.5 out of 10. It contains one ingredient with proven anti-wrinkle efficacy: Retinol (est. ≈0.1%), 
 the most effective non-prescription ingredient with well-proven efficacy to reduce wrinkles.
 
Among others, Rejuvi a Retinyl Serum also contains contains Retinyl Palmitate and Retinyl Acetate, two ingredients marketed as effective in reducing wrinkles. 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 Rejuvi a Retinyl Serum is rich (> 3%) in antioxidants, specifically Persea Gratissima (Avocado) Oil (est. ≈55.0%).

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.

Ingredients explained

Persea Gratissima (Avocado) Oil
Est. %55
Function
Origin
A fatty oil expressed from the fleshy part of an avocado, used in skincare for its excellent emollient and occlusive moisturizing properties. Avocado oil contains fatty acids, notably oleic acid (up to 80%), squalene, vitamin E, and carotenoids.
Propylene Glycol
Est. %22
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. %11
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.
Polysorbate 60
Est. %4
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.
Retinyl Palmitate
Est. %2

Tocopherol
Est. %1.9
Function
Origin
