Does UV light kill fungus?
Studies* have shown that (UV) C radiation is an effective therapy for infected nails.
Using Ultraviolet Light directed at the affected area can be very effective. In order to apply the correct treatment so the fungus does not return, it is important to also treat the shoes on the inside with the UV light. If the shoe is not treated, then the fungus can re-infect the toes. This is true whether you choose to use medication to treat the problem, or whether a UV light is used. The spores have to be killed for this re-infection not to happen. Of course with any therapy, when a novice takes on the task of treating the problem, it can become somewhat complicated. It always needs to be done with caution.
Many feel that UV therapy is the best treatment for nail issues. Whether this is true or not, it is becoming one of the most popular methods of treating nail fungus. The good thing about it is the fungal spores are completely destroyed by the light, therefore the fungus does not return. Any bacteria is also destroyed when using the light. The nail plate is also left in tact. With medications and creams, the nail plate can be left damaged.
Benefits of UV Lights for Nails Treatment
One advantage of using UV light for toenail fungus is the speed that it can work. Creams and medications usually take a fair amount of time to work. With the UV light, a cure and recovery are dramatically quicker. It must be used with caution however, since the UV light is able to quickly burn the skin. Therefore, starting at an exposure that is quite limited in time, and then slowly building up the time is required in order to avoid burning your skin. UV light is also able to affect a specific area. When putting cream on a fungal infection, the cream may not reach all of the spaces. With UV light, it will reach all of the spaces and can be more effective because of it.
Many people have concerns about the safety of a UV lamp. That is understandable and it is important to look into the safety of any procedures and equipment you use for anything. So long as you follow the directions and do not use the lamp longer then the recommended maximum exposure time, then there should not be any negative affects to your health.
UV radiation (UVR) used in most germicidal bulbs is harmful to both skin and eyes and known to cause cancer.
UV radiation is damaging to human tissue and particularly damaging to skin. UVB irradiation of skin has been particularly well studied, and is accepted as the main cause of skin cancer. UVC irradiation of human skin has been much less studied, but may be detrimental and its use must be supervised by professionals.
In proposing to employ UVC irradiation to treat onychomycosis, it is clearly of crucial importance to minimize or avoid UVC exposure to skin either surrounding the nails (perionychium, hyponychium and cuticle) or to the tissue underneath the nail (nail bed). The former can be prevented by careful masking of the area with UVC-opaque adhesive material, while the latter must be minimized by careful dosimetry calculated with reference to individual patients' nail thickness and optical properties
Treatment lengths will vary from just a few seconds up to a couple of minutes per day. This usually goes on for a couple of weeks in order to see a full recovery. Since fungus likes dark places, does uv light kill fungus? The UV light is effective because it is able to penetrate through the nail to the back side where the fungus usually starts and continues reinfecting.
Despite all of this, it is important to address any medical issues with a doctor before applying any solutions of your own. Fungal problems of the toenails is usually not very serious, but it can be uncomfortable with pain and itchiness. Talking to a medical professional about a condition like this is always recommended to make sure there is not something else going on.
UV-C lamps present minimum risk when used by professionals who know how to use them. They must shield their eyes and skin to avoid light damage and severe injuries to the eyes and skin. We advise customers to exercise caution when selecting equipment and look for evidence of third party testing as well as certification of device materials and electrical components by well-known organizations such as NSF, UL, CSA, DVGW-OVGW or other international requirements as applicable.
