Product Summary
"Peter Thomas Roth - Firm X Collagen Moisturiser" is a well-rounded moisturizing product. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Peter Thomas Roth - Firm X Collagen Moisturiser ticks this box. Humectants in this product (glycerin, hydrolyzed collagen, sodium hyaluronate, soluble collagen and butylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (hydrolyzed collagen, dimethicone, squalane, caprylyl glycol and isohexadecane) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
- We like that this moisturizer contains peptides (palmitoyl tripeptide-5 0.40% - 0.90% and palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine 0.40% - 0.90%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.

Firm X Collagen 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, hydrolyzed collagen.
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, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine, palmitoyl tripeptide-5
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin
Is helpful in restoring skin barrier function supporting its moisture levels. Is claimed to stimulte collagen production in skin but evidence is lacking
A peptide. It helps attract water to the upper layer of the skin, support skin's barrier function and might have some slight anti-aging effect through stimulating skin's own production of hyaluronic acid
