7 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: glycerin, mannitol.

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: butyrospermum parkii butter, cocos nucifera oil.

BUTYROSPERMUM PARKII BUTTERRole: HeroA 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~2.1–3.2%

CAPRYLIC/CAPRIC TRIGLYCERIDERole: Under-dosedA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~0.35–0.8%

COCOS NUCIFERA OILRole: Key activeAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~0.8–1.2%

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~4.2–6.4%

INULINRole: Key activeHelps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking~0.1–0.4%

MANNITOLRole: Key activeHelps to attract water to the upper layer of the skin~0.5–1.1%

PERSEA GRATISSIMA OILRole: Key activeAn emollient that helps soften the skin and could be helpful in repairing its barrier function~2.7–4.1%

Leuconostoc/radish root ferment filtrateA preservative that comes from radishes fermented by a bacteria. New research suggests that the preservation properties in the ingredient come from an ammonium salt that is not present naturally in radish root but used in its cultivation. Is problematic because the exact amount of the preservative agents is difficult to determineLow~0.05–0.2%est.

Comedogenic

Butyrospermum parkii butter ~2.1–3.2% — rinse-off or low %

Some risk

These ingredients have a comedogenic rating ≥ 2. In leave-on products at higher concentrations they can clog pores for acne-prone skin types.
