This product contains serine. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

What the product description says
“The perfect way to purge pores of impurities without leaving skin feeling tight or dehydrated, Shiseido’s Purifying Mask is the perfect way to restore clarity to skin without compromising softness.”
Source: Cultbeauty

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

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).

What the product description says
“An emergency skin-resetting mask with the botanical power of red Shiso, peels away dirt, pollutants and other sources of breakouts that become lodged in pores, while removing dead surface skin cells for brightened skin.”
Source: Boots

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.
