Black bandage is a highly respected beauty and skin care product. In order to give full play to its efficacy, correct use is very important. The following are my personal steps: first, clean the face thoroughly, then apply a proper amount of black bandage to the face and gently massage until it is completely absorbed. Be careful not to apply too much, so as not to cause skin burden. In addition, it is not recommended to use it with other functional skin care products. Only by using the right method can the black bandage exert the best skin care effect.
