Salt bath: it is to soak the skin with warm water and apply salt powder to the skin for "bathing", instead of massaging and rubbing the skin with salt, which will hurt the skin. This method was first popular in America. Practice has proved that brine flotation can not only sterilize, but also make the skin fit, with the effects of cleaning, moisturizing, acne removing, whitening and anti-wrinkle. It can also reduce fat and weight, lower blood pressure, and has certain curative effects on dermatoses, joint pain, rheumatism, hair growth and anti-aging.
