1. A method of treating a skin surface with a wrinkle, the skin surface overlying a collagen containing tissue, comprising:

  • identifying a person having a skin surface with a wrinkle;

    providing an energy source with an energy delivery surface;

    positioning the energy delivery surface in contact with the skin surface;

    producing energy from the energy source;

    creating a reverse thermal gradient, wherein a temperature of the skin surface is less than a temperature of the collagen containing tissue; and

    delivering energy through the skin surface to the collagen containing tissue and contract at least a portion of the collagen containing tissue with controlled cell necrosis, such that the depth of the wrinkle is reduced.
