*Please use "Wrinkle Shot Medical Serum Duo" before using an all-in-one product. *If using an all-in-one product, please use "Wrinkle Shot Geo Serum Protean" or "Wrinkle Shot Medical Serum" after the all-in-one product. ■Preparation before use Do not use Agent A and Agent B as they are before mixing. 1. Remove the cap from Agent A. Agent A container already contains 1.5 ml of Agent A. 2. Remove the tab from Agent B by twisting it. Hold the tube gently at this time to prevent the contents from splashing. 3. Place Agent B against the opening of Agent A container and pour Agent B into Agent A container. Be sure to put in the entire amount of Agent B. Be careful not to tip over the Agent A container at this time. 4. Reattach the Agent A cap that was removed in step 1 to the Agent A container and shake well at least 10 times. 5. Remove the Agent A cap and replace it with the included nozzle and main cap. Discard the removed Agent A cap. 6. Finally, be sure to write the mixing date in the [ / ~ ] section of the A container with an oil-based pen. If the date starts to fade, trace over it and rewrite it. *The serum that has been mixed should be used up within approximately one month from the mixing date, and should not be used after two months. ■Recommended amount to use and how to use: Use after washing or massaging. Remove the cap by twisting it off, turn the container upside down, and press the nozzle to take an appropriate amount (about 1.5 cm in diameter for the entire face) into your hand, and gently apply it to your entire face. Then, use lotion.
