Moisturizing
What does the product description say?
Dewy Hydration Duo
Source: 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:
betaine, 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, caprylic/capric triglyceride.

An emollient that helps soften the skin
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Anti-aging
