Works

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 acrylate/acrylic acid copolymer.

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, cetyl ethylhexanoate.

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~2.1–3.2%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~1.5–2.2%
Glyceryl acrylate/acrylic acid copolymerKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and provide a longer-lasting hydration. Can create a thicker product consistency~0.1–0.45%
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~1.6–2.5%
Cetyl ethylhexanoate· EmollientEffect: LowAn emollient that helps soften the skin and creates a thicker product texture~0.85–1.3%
AllantoinUnder-dosedHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.15–0.5%
