“Formulated with ZPOLY™ complex for enhanced redness-soothing and barrier-strengthening capability.”
Source: Zo Skin Health

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: galactoarabinan, 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: dimethicone, helianthus annuus seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~1.1–1.4%
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~4.5–5.5%
Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~3.5–4.3%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~3.1–3.8%
C12-15 alkyl benzoateKey active· EmollientEffect: MediumEnhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth~2.3–2.8%
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~1.5–1.8%
LactoseKey active· HumectantEffect: MediumHelps attract water to the upper layer of the skin~0.45–0.7%
Panthenyl triacetateKey activeEffect: HighA stable oil-soluble derivative of vitamin B5. It can help support skin barrier and reduce inflammation in skin~0.3–0.55%
GalactoarabinanKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.2–0.35%
Hydrolyzed alginKey active· HumectantEffect: MediumDerived from brown algae. Helps attract water to the upper layer of the skin~0.15–0.3%
Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~0.95–1.2%
AlginEffect: LowUsed to thicken product formulation. Can help attract water to the upper layer of the skin~0.2–0.35%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.2–0.4%
LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.25–0.45%
TocopherolEffect: Low, below effective dosePure 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~0.2–0.35%
Laminaria digitata extractUnder-dosedSeaweed extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but good research is lacking at the moment~0.2–0.35%
Lactic acidUnder-dosedAn 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)~0.15–0.3%

What the product description says
“Exfoliating properties provide ultra-mild exfoliation to prevent the signs of premature aging.”
Source: Face the future

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.These ingredients - magnesium aluminum silicate, panthenyl triacetate - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

What the product description says
“Provides mild enzymatic exfoliation to smooth bumpy texture”
Source: Zo Skin Health

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.
