What does the product description say?
"It offers naturally anti-ageing and anti-inflammatory properties to help promote collagen and circulation for a radiant and youthful appearance."
WIMJ summary

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.This ingredient - sodium salicylate - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

What does the product description say?
"Infused with Kaolin, the mask will gently eliminate impurities and exfoliate dead skin cells to leave the face feeling smooth, refined and renewed."
WIMJ summary

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.

WIMJ summary

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
