At a glance
Summary
This bath salt product contains several beneficial ingredients such as bentonite, kaolin, and allantoin, which are known for their skin-purifying and soothing properties. However, the presence of 'parfum' is a concern due to its potential to cause skin irritation and the lack of transparency regarding its composition. The overall formulation is mostly safe, but the inclusion of synthetic fragrance slightly lowers its rating.
