Exfoliation
No ingredient credited for this claim

What the product description says
“Byron 2-in-1 Mask and Scrub”
Source: Ulta

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.

Moisturizing

Works

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: jojoba esters, cetearyl alcohol.

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~3.8–5.6%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~3.3–4.9%
Jojoba estersKey active· EmollientEffect: HighAn emollient made of jojoba oil. Helps soften the skin and support its barrier function~2–3%
Macadamia ternifolia seed oilKey active· EmollientEffect: MediumPlant oil from nuts that helps soften the upper layer of the skin. Contains a high concentration of oleic acid that can weaken skin's barrier function and increase water-loss while enhancing penetration of other ingredients~1.5–2.3%
Stearic acid· EmollientEffect: LowHelps oil and water mix together and works as an emollient~2.5–3.7%
Glyceryl caprylate· EmollientEffect: LowAn emollient that can also help water and oil mix together, as well as prevent bacteria growth in products~1–1.5%
