What's the main difference between the sea salt and the coffee in this scrub?

While both sea salt and ground coffee contribute to the product's exfoliating function, they serve slightly different roles. Sea salt is the main polishing agent. Its harder, crystalline structure is particularly effective at lifting away built-up dead skin cells from tougher, drier areas of the body, leaving the surface noticeably smoother. This makes it a traditional choice for body scrubs aimed at rejuvenating rough skin on elbows, knees, and legs. Ground coffee, with its finer yet still granular texture, helps the scrub work more evenly across the body. It prevents the formula from being overly dominated by larger salt crystals, creating a more balanced and less abrasive overall feel during use. Beyond its physical role, coffee is often included in skincare for its rich content of antioxidant compounds. These are sought after for formulas intended to address skin that may look tired or dull, as antioxidants help to protect the skin's surface from environmental stressors. In this blend, the two ingredients work together: the salt handles the deeper smoothing, and the coffee helps with an even application and adds a supportive element for skin appearance.
