The technique of giving your back-acne facial in a spa is what it sounds like; it involves taking care of your back's skin in the same way you would usually take care of your face.Estheticians often use a steaming session to open the pores and prepare the body for the more delicate parts of the back-acne facial.The process of a back facial then entails washing, exfoliating, and moisturizing the skin on the back before putting on a mask.
