The present invention generally relates to improved medical devices, systems, and methods, with exemplary embodiments providing improved cooling treatment probes and cooling treatment methods and systems. In some embodiments, freezing of the skin may be desirable to effect the hypopigmentation of the skin of the patient. Generally, embodiments may limit supercooling of the skin of the patient during a cooling treatment. Additionally, embodiments may limit adverse side effects such as hyperpigmentation. It has been found that the freezing behavior (frequency and time to freeze) can be modified by adjusting the thermal parameters of the cooling applicator. Accordingly, in some aspects of the invention, a method of treating the skin may be provided where the thermal parameters of the cooling applicator are adjusted during treatment.
