Therefore, it's important to ensure that the ingredient is one of the last few ingredients to be listed on a product.
You may also see himalyan salts used in natural and organic skincare which are used to cleanse and purify the skin. Packed with minerals, himalayan salt can detoxify the skin, stimulate circulation and help reduce cellulite. Ideal for soaks and scrubs but if you have super dry skin we would recommend using in small doses as can exacerbate dry skin conditions.
