Does fluorescent lamp irradiate the skin for a long time have an effect on the skin?

Long-term exposure to the skin by fluorescent lamps will have an impact on the skin.

Long-term exposure of the skin to fluorescent light will have a certain impact on the skin. The ultraviolet rays in fluorescent lamps directly irradiate the skin for a long time, which easily leads to melanin deposition inside the skin, resulting in dull skin color and spots. Long-term irradiation will cause dry and dull skin, which will easily lead to skin lesions for a long time.

It is suggested that if you work under fluorescent light for a long time, you must do a good job of skin isolation and sun protection. You can wear a hat and mask to isolate the light from direct contact with the skin.

Extended data:

Photodermatosis refers to various pathological changes on the skin caused by sunlight or other light sources, including the so-called photosensitive dermatoses and some dermatoses that are only promoted or aggravated by light during their occurrence and development. In addition, sunlight can also lead to premature aging of the skin and even precancerous lesions.

The light source that causes this disease is mainly the ultraviolet part of sunlight, among which the short-wave ultraviolet (UVC) with the wavelength of 200-290nm has a great killing effect, but it generally does not reach the ground. The wavelength of 290-320nm is UVB, which can cause skin erythema and various light-source dermatoses, but it can't penetrate the window glass. The wavelength of 320-400nm is long-wave ultraviolet (UVA), which can only cause skin lesions in the presence of some photosensitive substances. Visible light and infrared light have longer wavelengths and less energy, resulting in little photosensitivity.

Although artificial light sources are not as strong as sunlight, they can also cause reactions if they can release light with a specific wavelength to a certain extent, such as white fluorescent lamps. The light effect of skin can only be produced by absorbing light. Some tissue molecules only absorb light with a specific wavelength (absorption spectrum), and the light most easily absorbed by molecules (action spectrum) is closely related to the luminescence effect.

Normal skin can cause temporary erythema, melanin formation, epidermal cell proliferation and skin degeneration under ultraviolet irradiation. Lipids, sweat and cuticle of epidermis, especially melanin, can absorb or reflect a certain amount of light, which is an important barrier to prevent ultraviolet rays from penetrating into dermis. Therefore, normal skin can receive a certain amount of ultraviolet radiation without causing pathological changes.
