The cooling system (100, 300, 400, 500, 700, 750) includes an applicator (101, 501, 701) configured to hold a predetermined amount of solid coolant and fluid coolant (117) to cool a targeted area of the body (162, 570) to crystalize the lipid-rich cells underneath the targeted area to reduce the fat cells. The applicator may include a thermoelectric cooler (TEC, 136, 704, 706) where the hot side is cooled by coolant held within the applicator. The cold side of the TEC may be thermally coupled to a cooling plate (138, 560) configured to cool a targeted area of the skin at a predetermined temperature range for a predetermined period of time. The cooling system may also be used to relieve localized pain at certain area of the body and/or utilized for cryotherapy.
