Review

Results you may expect from using Paula's Choice Peptide Booster:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Paula's Choice Peptide Booster:

  • Moderate moisturizing. It has a moisturizing rating of 5.1 out of 10.
  • Little anti-wrinkle effect: Paula's Choice Peptide Booster has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

How moisturizing is it?

Quite moisturizing: Paula's Choice Peptide Booster has a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Paula's Choice Peptide Booster 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, Paula's Choice Peptide Booster also contains some ingredients marketed as effective in reducing wrinkles, specifically Tripeptide-1, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Palmitoyl Hexapeptide-12, and Adenosine. 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.

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.
Glycerin
Est. %6
Function
Origin

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

PEG-8 Dimethicone
Est. %4
Function
Origin

Tripeptide-1
Est. %0.3
Function
Origin

A small, skin-identical peptide that boosts collagen renewal in the skin and improves other structural proteins. It may have trouble penetrating the skin in this form, so palmitic acid or biotin is usually added to it.

Palmitoyl Tripeptide-1
Est. %0.3
Function
Origin

A small peptide consisting of three amino acids with anti-wrinkle effects. Together with Palmitoyl Tetrapeptide-7, it is a part of the popular anti-wrinkle complex called Matrixyl™ 3000.
