“Starry Nights Neck Cream”
From product name

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: butyrospermum parkii butter, glycine soja oil.

Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA 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~1.3–1.6%

Isopropyl palmitate· EmollientEffect: LowHelps soften the upper layer of the skin and create a thicker product consistency~0.65–0.95%
Stearic acid· EmollientEffect: LowHelps oil and water mix together and works as an emollient~8.6–10.5%

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

Butyrospermum parkii butterEffect: LowA 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~1.3–1.6%
