Highly recommended to gradually increase the suction level and use the tool after opening the pores with a hot towel or facial steamer. It's also important to avoid using the tool in one place for more than 5 seconds and to gently slide it up and down in one direction. Here are some general guidelines on how to use the five suction levels that usually come with CHIMOCEE Pore Vacuum: Level 1: This suction level is typically the lowest and is suitable for those with sensitive skin or those who are new to using a pore vacuum. To use it, start with this level and gradually increase the suction as needed. Level 2: This suction level is slightly higher than Level 1 and is suitable for those who have normal skin or mild impurities. To use it, place the pore vacuum over the targeted area and move it in circular motions for a few seconds. Level 3: This suction level is suitable for those with oily or combination skin, or those who have more stubborn impurities. To use it, place the pore vacuum over the targeted area and move it in circular motions for a few seconds, applying slightly more pressure than at Level 2. Level 4: This suction level is suitable for those with more problematic skin, such as acne-prone or congested skin. To use it, place the pore vacuum over the targeted area and move it in circular motions for a few seconds, applying more pressure than at Level 3. Level 5: This suction level is typically the highest and is suitable for those who have very stubborn impurities or very oily skin. To use it, place the pore vacuum over the targeted area and move it in circular motions for a few seconds, applying the most pressure of all the suction levels. However, it's important to use caution and not apply too much pressure or use it for too long in one area to avoid damaging the skin.
