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, simmondsia chinensis seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: paraffinum liquidum, petrolatum

Product summary

Based on the ingredient list, "Kose - CoenRich Q10 Brightening Tone Up Hand Cream" can work well for skin moisturization. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (glycerin, hydrolyzed collagen, sodium hyaluronate 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). Paraffinum liquidum, petrolatum, hydrolyzed collagen, dimethicone and simmondsia chinensis seed oil 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.

Irritation risk
