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: algae extract, betaine.

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: algae extract.

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~4.8–7.2%

Exfoliation
No ingredient credited for this claim
No evidence
What the product description says
“Ultra-hydrating and refreshing, this multi-action treatment lotion gently softens by removing dead skin, while smoothing and moisturizing for next-level luminosity.”
Source: Bluemercury

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
