Product Description This serum smooths and firms the skin on areas of concern with simple application. Formulated with herbs that have been cherished for beauty and health since ancient times, this serum can be used on the entire body and does not require massage or rinsing.

Dispense an appropriate amount from the dropper into your palm and apply to areas of concern such as the upper arms, abdomen, waist, and thighs. Apply to the entire area, not just a specific spot. 3. After application, relax in a warm room where you won't sweat, or go to sleep. * It is recommended to drink plenty of water during the usage period, more than usual. * While you can use it daily, we recommend using it every 2-3 days. * There is some damage to the outer box (see photo 4). * Please purchase if you are not concerned about home storage.
