Are phototherapy lights harmful to the skin, and can strong lights hurt the skin?

When doing nail art, I will put my hand directly in the light therapy lamp, which has a strong penetrating power, which will go directly to the dermis layer, so that the collagen fibers and elastic fibers will be damaged, and even lead to wrinkles and aging. If you often shine on the light therapy lamp, it will also make the ** dark.

The light therapy lamp used to harden the gel has ultraviolet rays, and long-term and frequent use may increase the risk of ** cancer, because the hands are often exposed to the light therapy lamp, it is recommended to wear sunscreen before phototherapy.

It is better to do as little phototherapy as possible, after all, ultraviolet rays are the main cause of aging.

Follow-up: Isn't it ultraviolet light? Will it make the hands blemised or darkened?

The biggest enemy of phototherapy gel is sunscreen, but for customers, that level is fine. It's like when you go out in the sun.

But some people's ** is not necessarily, I have a senior brother who changed the lamp, causing **sunburn, wow. What a scary piece·· Follow-up question: Oh my God, is the 9w one relatively better?

But it takes a long time ... It's not a matter of wattage, it's a problem of the rays of the lamp! You go and see some nail art books that will introduce this problem!

It won't be harmful, it just accelerates the rapid drying of the phototherapy gel, and it is not harmful to **.

Addendum: Phototherapy is the use of sunlight, visible and invisible light from artificial light sources to prevent and treat diseases. Phototherapy began with daylight**, which was documented as early as the 2nd century AD.

Artificial light sources began at the end of the 18th century, and by the middle of the 19th century, visible light, infrared, ultraviolet light, etc. were formed one after another, and then were widely used and developed in various fields of clinical **. Phototherapy mainly includes ultraviolet light, visible light, infrared, and laser. Infrared rays act on the human body mainly to improve local blood circulation, promote swelling and subsidence, analgesia, reduce muscle tone, relieve muscle spasms and dry exudative lesions.

1. Scientists have known for a long time that bright light can change the brain's internal clock, and the brain's internal clock can control a person's sleep. A recent study has shown that ordinary indoor light can also affect the body's biological clock. The long-term use of indoor lighting has invisibly disrupted the biological clock set by the ancestors for people, so as to change the inherent physiological pattern of the human body.

This will not only advance the age of maturity of human beings, but also make people's physiological rhythm disordered, and then appear palpitations, chest tightness, mental malaise and other phenomena. Other researchers believe that the strong light waves emitted by indoor lighting can cause genetic degeneration of a large number of cells in the human body, causing the increase of abnormal cells and the death of normal cells.

2. Working under the light for a long time not only causes eye fatigue, but also reduces the body's ability to absorb calcium. Because there is a big difference in the nature and intensity of light and sunlight. Natural light contains many colors and wavelengths, while indoor lighting only has yellow, orange and red, and lacks the beneficial ultraviolet rays in sunlight, so the absorption of calcium is greatly reduced.

In addition, the light emitted by the fluorescent lamp has blue and invisible ultraviolet rays, which are overabsorbed by the human body and are likely to make people's ** cancerous.

3. For this reason, experts suggest that it is best to use natural light during the day, and open the windows frequently to let sunlight into the room; People who work at their desks all day long in the office should take time out to avoid contracting modern lighting diseases. When indoor lighting must be used, the following five principles should be grasped: use a wide range of lighting, such as when reading a book on a desk, the light should shine on the entire desktop; Use uniform lighting, which means that the illumination of each part of the illuminated place should be consistent; Maintain stable lighting, and the light source should not be dim or flickering; There is no uniform standard for maintaining adequate lighting, which generally depends on the nature of the work, that is, the finer the work, the higher the illumination required; Finally, be careful not to let the light shine directly into your eyes.

No, only long-term exposure to lamps like ultraviolet rays has a certain effect on the human body.

Some. No matter what light has an impact on **. The lamp also contains ultraviolet rays, but we can't see it, so you need to apply a barrier and sunscreen. Especially if you don't have your face in the direction the light is shining from.

Yes, if you stay in a certain place for a long time, it will always bring some damage to Ziji's **, it will make the **surface layer form pigment and make ** appear dull and dull.

No, except for ultraviolet light.
