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, 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: dimethicone, ethylhexyl palmitate.

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~2.5–3.1%
Peg/ppg-18/18 dimethiconeKey activeEffect: HighA silicone that mixes with water creating nice light-weight product texture~1.5–1.8%
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~5.4–6.6%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.6–0.9%
TrihydroxystearinKey activeEffect: MediumHelps soften the upper layer of the skin and improve the product texture~0.3–0.6%
Ethylhexyl palmitateKey active· EmollientEffect: MediumAn emollient that helps soften the skin and create a nice product texture~0.35–0.65%
Polysilicone-11Effect: LowA silicone that forms a light film on the skin surface helping to bind water and temporarily absorb oils creating a matt and powdery feel~2.1–2.6%
Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~0.25–0.5%
Cetyl peg/ppg-10/1 dimethiconeEffect: LowA type of silicone that helps water and oil mix together. Can help to soften upper layer of the skin~2.8–3.4%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~4.3–5.3%
