Covey Skin Last But Not Least Moisturizer

Judging from the ingredient list, "Covey Skin - Last But Not Least Moisturizer" works well for improving skin hydration This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (copper pca, glycerin, sodium hyaluronate, sodium pca and zinc pca) 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 (palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, caprylic/capric triglyceride, squalane and cetearyl alcohol) 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 tetrapeptide-7 0.05% - 0.20% and palmitoyl tripeptide-1 0.10% - 0.35%). 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.
