Peter Thomas Roth Firm X Collagen Moisturiser

"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.
