“Oil-Free Moisturiser”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, hyaluronic acid.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, cetyl alcohol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
Anti-aging2 ingredients credited for this claimLimited support
“Hydrates the skin Fights against premature ageing.”
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - hyaluronic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
Anti-blemish2 ingredients credited for this claimWeak support
“Provides excellent relief for temporary dryness that accompanies acne treatment programmes.”

Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect

Product summary
"Peter Thomas Roth - Oil-Free Moisturiser" has a good moisturizing formula. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Panthenol, glycerin, hyaluronic acid, sodium pca and methyl gluceth-20 in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Dimethicone, cetyl alcohol, vegetable oil and glyceryl stearate in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
- this moisturizer includes a form of retinoids (vitamin A) - retinyl palmitate 0.45% - 0.65%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
- This formulation also includes panthenol (pro-vitamin B5) at about 0.55% - 0.85% concentration. In this concentration, panthenol works effectively to improve the skin barrier and reduce inflammation.
Irritation risk
This moisturizer contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here
