Partial weight loss's external slimming instrument uses "cross-induced current" to improve flabby muscles, and introduces the effective active ingredients of external slimming drugs into subcutaneous tissue, thus improving the original poor circulation. Among them, the effect of "hyperthermia" makes the skin capillaries dilate, the local skin temperature increases obviously, the microcirculation function is strengthened, and the skin's ability to absorb effective components is enhanced. The metabolism of local tissues will also accelerate. With the increase of fat cell volume, the subcutaneous tissue and capillary network tissue (blood and lymph) of obese people will be compressed, the metabolic circulation function will be reduced, water and toxins will remain, and the skin tissue will be slack, so the skin surface will become rough and uneven, and the so-called "orange peel" phenomenon will appear, that is, cellulite. The most common sites of cellulitis are abdomen, buttocks, thighs, arms and waist. Therefore, cellulitis is also one of the important causes of local obesity. To improve this situation, we can adopt "cross-induction current" nursing, introduce active ingredients into subcutaneous tissue, activate its lipolysis process, discharge the accumulated water in surface tissue, and improve the exchange of blood and lymph in this part, which not only improves the function of cells, but also promotes the elimination of toxic waste. Thereby improving the condition of cellulitis.
