Start with the ultra-soft microfiber side to effortlessly remove makeup, dirt, oil, and even stubborn waterproof mascara. Then flip to the exfoliating side to gently slough off dead skin cells and clear clogged pores - use this side daily or 2-3 times a week, depending on your skin's needs. Both sides deliver a daily dose of collagen to help reveal a bouncy, dewy, glowing complexion. For optimal results, replace every 60 days.
