Moisturizing

9 ingredients contribute at the levels below

Good evidence

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: cyclomethicone, 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: beeswax, butyrospermum parkii butter.

BEESWAXRole: HeroForms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen~1.3–1.6%

BUTYROSPERMUM PARKII BUTTERRole: Key activeA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~5.8–7.1%

CAPRYLIC/CAPRIC TRIGLYCERIDERole: Key activeA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~4.6–5.7%

CERA ALBARole: Key activeForms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen~1.8–2.2%

CYCLOMETHICONERole: Key activeA type of silicone that leaves a nice silky finish on the skin and can help soften its upper layer~3.3–4%

DIMETHICONERole: Key activeA 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~2.6–3.2%

FAEX EXTRACTRole: Key activeYeast extract. Helps attract water to the upper layer of the skin~0.95–1.15%

GLYCERINRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.55–0.85%

YEAST EXTRACTRole: Under-dosedHelps attract water to the upper layer of the skin and might have some anti-oxidant and skin lightening properties. It can help calm down inflammation in skin~0.7–1.05%
