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.

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, isopropyl myristate.

Isopropyl myristateKey active· EmollientEffect: HighAn emollient that helps soften the skin. Could be comedogenic~4.5–6.7%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~0.5–1.1%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.7–4.1%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~1.4–2.2%
Glyceryl stearate seKey activeEffect: MediumUsed to stabilize the product formulations and works as an emollient~1–1.5%
Stearic acid· EmollientEffect: LowHelps oil and water mix together and works as an emollient~1.8–2.7%
Isohexadecane· EmollientEffect: LowImproves the texture of the product and helps soften the skin. Helps oil and water mix together and can be used as a cleansing agent~0.9–1.4%
Aloe barbadensis leaf extractEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.15–0.6%
