Soft wax works better on large areas, like the back or legs, and is recommended for removing fine hairs. Since it adheres to the skin, it also has an exfoliating effect. This makes it more painful than using hard wax and not suitable for applying twice in the same area. On the other hand, Brazilian blue wax and calendula hard wax are gentle on the skin, which makes them more suitable for sensitive areas, like the face or the bikini line. They are also easier to clean up, leaving little residue on the skin, and do not require depilatory strips.
