Abstract
A skin treatment device provides feedback to a user relating to the force or pressure they are applying. In addition to the feedback provided for indicating that the pressure is too high, correct, or too low, there is a further feedback type when the force or pressure is below a lowest threshold value, indicating that there is no contact between the skin and the device. Providing the same feedback information when the user is applying a too low pressure as when the user has deliberately released the device from contact with the skin is thereby avoided.
