How long can the black plaster last?

If the black plaster is applied according to the normal method, it can be removed after 8- 12 hours each time. The reason is that during this period, human skin has absorbed the effective components of the plaster, but if the plaster is not removed in time, it will increase the burden on the skin, hinder the permeability of skin pores, hinder the normal breathing of the skin, and hinder the normal discharge of sweat, which will seriously lead to dermatitis and other symptoms on local skin, which will bring many adverse effects to people's health.
