What the product description says

“A nighttime skin-refining face moisturizer enhanced with a hydroxy acid blend for gentle exfoliation and overnight hydration for dry skin.”

Source: Skinceuticals

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, aloe barbadensis extract.

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: caprylic/capric triglyceride, dimethicone.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.8–4.2%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA 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~0.55–1.3%

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~3.8–5.7%

Saccharum officinarum extractKey activeEffect: HighSugar extract that helps attract water to the upper layer of the skin~0.8–1.2%

Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~2.1–3.2%

Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~0.35–0.85%

Aloe barbadensis extract· HumectantEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~5.4–8%

Exfoliation

No ingredient credited for this claim

No evidence

What the product description says

“10% hydroxy acid blend works synergistically to gently exfoliate dead skin cells”

Source: Skinceuticals

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.
