Directions Adults and Children Over 2 Years of Age
- Using only warm water and a washcloth, clean the lip area of any lip preparations, lotions, ointments, residual beverages, or cosmetics, including lipstick.
- Remove the cardboard cap from the applicator end and place the cardboard cap onto the glass/plastic vial end, opposite the brush end of the product.
- Squeeze the cardboard cap to break open the inner glass vial.
- Saturate the applicator end with solution by holding the brush end down and squeezing the container until you can see liquid on the brush applicator.
