Keen is for kids (ages 8+) and adults who are ready to change.  If you bring the willingness, Keen provides the awareness.  With these two key ingredients you have the power to take control of your subconscious Body Focused Repetitive Behavior (BFRB).  Keen is not a magic wand that will stop your BFRB, but it is an instrumental tool in the process toward sustainable behavior change.  Keen provides the awareness, allowing you the choice to stop.  While we suggest 8+ some children younger have developed the ability to understand the concepts and payoff while others older have yet to get to that point, as each person is unique.   We encourage parents to talk with their kids to ensure they are ready for change before ordering.
