What the product description says
“ESSENCE MOISTURIZER”
From product name

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: hyaluronic acid, sodium hyaluronate.

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: ceramide eop, ceramide np.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, ceramide eop, ceramide np, palmitoyl pentapeptide-4, palmitoyl tripeptide-5

Hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin.

Product summary

Judging from the ingredient list, "Le Mieux - ESSENCE 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. Acetyl hexapeptide-8, hyaluronic acid, sodium hyaluronate, sodium hyaluronate crosspolymer and sodium pca 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). Emollients in this formulation (ceramide eop, ceramide np and caprylyl glycol) 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

  • As a plus, this moisturizer also contains ceramides (ceramide np 0.45% - 1.05% and ceramide eop 0.50% - 1.15%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
  • This moistruizer also contains peptides (palmitoyl tripeptide-5 0.50% - 1.20%, palmitoyl pentapeptide-4 0.85% - 1.30% and acetyl hexapeptide-8 1.30% - 1.90%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, 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 peptides in skincare are helpful. They 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.
