Users often feel immediate relief after the first 20 minutes of use. For long-term benefits, we recommend regular use for at least 20 minutes a day. We recommend to use it at least 1 time a day before going to bed. For greater benefits, we recommend using it 2 times a day, once in the morning as soon as you wake up and once before bedtime. It can be used at any time of the day if you need relief.
