AThe default treatment time is 15 minutes. Please restart it for further continuous use. The recommended usage time is : 1. micro vibration cleaning: depends on your habits 2. ultrasonic deep cleaning: 3-5 minutes for whole face. 3. EMS + vibration: for 10 minutes (5 minutes for the left face and 5 minutes for the right face)

AFor normal cleansing, brush area needs to be used with cleansing gel.

AWe recommend to use it 2-3 times a week. 10mins per time.

AMetal area(EMS+ positive ion) is for deep cleansing, it is necessary to remove make up before using. We recommend to use it 2-3 times a week.

ABrush area is for normal cleansing. Normally, It can be used every day. The skin type and sensitivity of each person are different. If you are using it for the first time, please use it 2-3 times a week first. Choose a weak vibration gear, and then slowly increase the frequency of use. Do not use it for more than 1 minute each time. Gently put it on your face and do not rub it hard .

ABrush area is for normal cleansing, it needs to be used with cleansing gel. Metal area(EMS+ positive ion) is for deep cleansing, It is recommended to be used with toning lotion, water-based skin care products or clear water to reduce friction.

AThe product has reached IPX5 waterproof grade and can be washed with water normally, as long as the water is not left to the charging port.

AThe interference intensity is directly proportional to the concentration of negative ions. The concentration of negative ions of EH-100 is very high, which is above 10 million ions / cm3. If the negative ions concentration of other products aren't high , the interference will be very weak naturally. In addition, due to the different conductivity of each human body, there will be different interference strengths.

AThis is a normal phenomenon. The negative ion concentration of EH-100 is more than 10 million ions / cm3. (see the actual test chart as left, It has reached 14.69 million ions /cm3. Due to the high concentration of negative ions generated, the negative ions will float in the air, and our hands are also a conductor. When we touch the volume button of BT, the negative ions will be brought there. When the concentration of negative ions is high, there will be a slight interference to BT, which will produce this interference phenomenon. When the hand leaves, the interference disappears, so there will not affect your normal use.
