Salt and sugar scrubs are two common types of mechanical exfoliants. Both may seem similar, but there are a few key differences between them. To find out what they are, plus more about physical exfoliation in general, we consulted with Dr. William Kwan, a board-certified dermatologist based in San Francisco, California. The Benefits of Physical ExfoliationPhysical exfoliation involves sloughing away built-up dead skin cells on the surface that can cause a rough texture and dulled complexion. This helps your skin absorb subsequent products better and can help you achieve a brighter, more even complexion. The Difference Between Salt Scrubs and Sugar Scrubs“Salt scrubs tend to boast larger particles that are grittier,” Dr. Kwan says. “Sugar scrubs have smaller particles and tend to be gentler on the skin. [They] are often less drying and less abrasive than salt scrubs.” This is why Dr. Kwan recommends sugar scrubs for sensitive and dry skin types and for use on the face and décolletage.How to Use Salt and Sugar Scrubs on the BodyThe key to successful exfoliation is approaching it with a gentle touch. You never want to rub too harshly, as doing so can wreak havoc on the skin’s surface. The American Academy of Dermatology (AAD), suggests applying a scrub in small and circular motions and rinsing off with lukewarm water. Follow up with a hydrating lotion.How to Use Salt and Sugar Scrubs on the FaceExfoliating can help remove dirt and impurities from your skin’s surface, but it shouldn’t take the place of daily cleansing. Cleanse first and then exfoliate damp skin using light, circular motions. Follow with a hydrating serum and moisturizer.  Our Favorite Sugar and Salt ScrubsL’Oréal Paris Pure-Sugar Nourish & Soften Cocoa Face ScrubType of scrub: SugarScrub uses: FaceGive your pores a sweet treat with this sugar scrub formulated with finely crushed cocoa, coconut oil and rich cocoa butter.
