1. Use LED lights or UV+LED lights

LED lights are visible light, wavelength 400mm-500mm. Like ordinary lighting light, it has no harm to human skin and eyes. In contrast, LED lights are more energy -saving than UV lights. The lighting time is shortened but the corresponding price is slightly more expensive than the UV light. LED lights will not make the skin have melanin precipitation. Furthermore, LED lights are not as hot as UV lights, and they will not burn hands or feet.

The new type of phototherapy lights are verbally talking about UV+LED lights. The advantage is that the service life is long, the power is low, the heating is low, the ultraviolet source is more stable, and the penetration ability is stronger. Therefore, it will not have much impact on the dry skin.

2. Pay attention to the aging of the lamp tube and replace it in time

Note that the service life of the UV lamp can also have a certain impact! After the use of the lamp for more than 5 months, the ultraviolet rays released by it will become unstable, so each lamp tube needs to be replaced before 6 months.

3. Pay attention to the length of illumination

The lighting time of the UV light will make the skin melanin emerge, so be sure to pay attention to the operation time.

Bottom gum: UV120 seconds/LED60 seconds

Color gum: UV60 seconds/LED30 seconds

Seal: UV120 seconds/LED60 seconds

Washing -free seal: UV180 seconds/LED90 seconds

4, do hand care work

Before and after the UV light is used, it is best to apply hand cream on the back of the hand, and every joint of the fingers to replenish the moisture on the hand, so that the guest's hands will not be too dry!
