Directions: 1. First place the handle on the roller, then remove the protective cap. 2. Gently roll across the entire face for absorption. For optimal results, start rolling from areas with deep wrinkles (neck, smile lines, forehead). 3. Use for 3~5 minutes until the hyaluronic acid melts into the skin and then the roller becomes blunt. * First apply the ampoule on the face and neck, then use the roller. * Intended for a single use only. Please remove and discard the roller after use. * Once opened, use immediately
