I am using patanjali products since many years. Patanjali has many good products which I like most and some bad products too. And the face wash is one of the good product of patanjali. As it has only natural ingredients so it is purely a herbal product.
So it has not any side effect. As my personal experience it is a very good product. My skin is very oily but after using it all the dirt and moisture are washout and the face turns fair. And I would personally recommend this face wash for those who have oily skin.
