Based on the ingredients included, "SkinMedica - HA5 Hydra Collagen Replenish and Restore Hydrator" works well for moisturizing the skin. 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. Urea, glycerin, glyceryl glucoside, hydrolyzed hyaluronic acid and polyglutamic acid 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 (linoleic acid, linolenic acid, passiflora edulis seed oil, shorea stenoptera seed butter and caprylic/capric triglyceride) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

HA5 Hydra Collagen Replenish and Restore Hydrator

Source: 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: glycerin, glyceryl glucoside.

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: caprylic/capric triglyceride, linolenic acid.
