What the product description says
“Seaweed Cleansing Soap”
Source: Mario Badescu

This product works by removing dirt and oil from the surface of the skin.

It contains the following cleansing agents that tend to be harsh on the skin: sodium laureth sulfate.

Keep in mind that cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

Exfoliation

What the product description says
“Exfoliating Seaweed Grains: Detoxes the skin with high amounts of vitamins.”
Source: Mario Badescu

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.
