What the product description says
β€œExfoliating Organic Fat Soap”
From product name

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
Side benefit Β· Glycerin, Prunus amygdalus dulcis oil
Works

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 β€œpull 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).
