Peter Thomas Roth Oil-Free Moisturiser

"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.
