The Oral Care Duo features a stainless steel tongue cleaner and gentle silicone lip exfoliator. 1. LIP EXFOLIATOR: The double sided silicone lip brush allows gentle exfoliation and massages for smooth, plump lips. Thin bristle side helps exfoliate lips, round bristles help stimulate blood circulation for fuller lip appearance. *Instruction: Apply your favorite sugar lip scrub or lip oil and gently massage your lips in circular motions. When finished, rinse, sterilize, and allow lip exfoliator to dry before storing for the next use. 2. TONGUE SCRAPER: Keep breath smelling fresh with the tongue cleaner that removes food residue, plaque and excess epithelial cell build up. The mini-size tongue cleaner (3/4" wide) can be used to clean the entire tongue without triggering the gag reflex. It's made with non-toxic and high-quality stainless steel. *Instruction: Gently glide the scraper down the tongue from top to bottom 2-3 times. Rinse tongue & scraper in between each usage.
