Abstract: Embodiments included herein are directed systems and methods for energy-based tissue treatment and chilling. Embodiments of a system may include an energy generator configured to generate a signal. The system may further include at least one antenna configured to receive and transmit the signal. The system may also include a chiller exposed, at least in part, to a housing or cooling fluid that is exposed to a housing of the at least one antenna. The system may additionally include at least one field spreader corresponding to the at least one antenna. Furthermore, the system may include a cooling plate configured to cool an epidermis and a dermis.
