What should I do to prevent my hands from turning black?
1. Use LED lights or UV+LED lights
LED lights are visible light, with a wavelength of 400mm-500mm, which is the same as ordinary lighting, and has no harm to human skin and eyes. In contrast, LED lamps are more energy-efficient than UV lamps, and the lighting time is shortened, but the corresponding price is slightly more expensive than UV lamps. LED lights will not cause melanin precipitation on the skin; moreover, LED lights are not as hot as UV lights and will not burn hands or feet.
The new type of phototherapy lamp we are talking about is the UV+LED lamp, which has the advantages of long service life, low power, low heat generation, more stable ultraviolet source, and stronger penetrating ability. Therefore, the dryness of the skin will not be affected much.
2. Pay attention to the aging of the lamp and replace it in time
Note that the service life of UV lamps will also have a certain impact! After the lamp has been used for more than 5 months, the ultraviolet light emitted by it will become unstable, so each lamp needs to be replaced before 6 months of use.
3. Pay attention to the length of light
Excessive UV lamp lighting time will make skin melanin appear, so be sure to pay attention to the operating time.
Primer: UV120sec/LED60sec
Color glue: UV60 seconds/LED30 seconds
Sealing layer: UV120sec/LED60sec
No-wash sealing layer: UV180sec/LED90sec
4. Do a good job of hand care
Before and after each use of the UV lamp, it is best to apply hand cream on the back of the hand and each joint of the finger to replenish the moisture of the hand, so as not to make the customer's hand too dry!
