Salt scrubs provide an excellent form of exfoliation, and can be used all over the body. These scrubs can be purchased in drugstores, spas and may also be made at home. Ingredients in salt scrubs differ by brand and formulation, but they all have three main ingredients in common.
Salt
The key ingredient to a salt scrub is obviously salt. Salt used in salt scrubs can be nearly any type, from regular table salt, to Dead Sea salts, kosher salt or bath salts. Salts which are more finely ground provide a gentle and even exfoliation. Very coarse salts can be rough on the skin, especially in delicate areas. The exfoliating action of the salt removes dead skin cells, allowing skin to rejuvenate.
Oil
Skin must be moisturized after it is exfoliated and oil provides that function. It also works as a delivery mechanism. A variety of oils may be used, from household canola oil and olive oil, to fragrant almond oil. Some oils, like olive oil or canola oil, allow for the salt scrub to be stored longer. Oils can even be mixed, creating the feeling, scent and consistency you want.
Scent
Scent is not an absolute necessity, but it can provide therapeutic aromatherapy benefits. Lavender, for example, is relaxing. Scent may also linger on the skin after the scrub is washed off. Essential oils are a good choice for imparting fragrance; just a few drops are sufficient. Spices, such as ginger and cinnamon, can also be used, as can citrus peels.
Other Ingredients
Aside from salt, oil and scent, other ingredients may be found in salt scrubs for added skin benefits. Additional exfoliants, such as ground almonds or coffee grounds, may be included for even deeper exfoliation. Glycerin soap may be added to help with removal of the oil. Dried flowers and herbs are added for appearance.
