Do not let water drip into your herbal sugar scrub. A small spoon or wooden spatula (usually included) should be used to scoop out the amounts needed for use. Do not dip wet utensils or wet hands in the scrub. Water causes the sugar to harden and will make the scrub difficult to use.
SN: Only whipped sugar scrubs and body polish are perfectly fine if water gets in them, since they have extra ingredients that can absorb the water. Still, utilize caution for longer use.
