Source: Skinstore

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, trehalose.

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: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover.

Product summary

Judging from the ingredient list, "Paula's choice - PC4Men Soothe + Smooth" 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. Glycerin, trehalose, methyl gluceth-20, bis-peg-18 methyl ether dimethyl silane and butylene glycol 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). Palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, bis-peg-18 methyl ether dimethyl silane, caprylyl glycol and pentylene glycol 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 also contains Peptides (palmitoyl tetrapeptide-7 1.20% - 1.80% and palmitoyl tripeptide-1 1.40% - 2.10%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that they are helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
  • Salicylic acid (1.25% - 2.50%) in this product will have an exfoliating effect and help smooth the skin. We, however, do not recommend using a moisturizer with Salicylic Acid daily to avoid over-exfoliating.
  • Dipotassium Glycyrrhizate in this product (0.90% - 1.40%) can also further help improve the skin barrier. It might be able to calm down inflammation and reduce sensitivity. Dipotassium Glycyrrhizate is an active compound from the licorice root.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: allantoin
