It uses tiny sea salt particles, ranging in size from 0.5 to 1 mm. Don't underestimate these tiny particles; they're a powerful exfoliator. Unlike regular exfoliators, these sea salt particles gently remove dead skin cells from the skin's surface without leaving any microscopic tears. This makes it an ideal choice for sensitive skin or post-operative skin. Studies have shown that over 80% of people with sensitive skin experience a noticeable reduction in skin discomfort after using an exfoliator containing these fine sea salt particles.
