Ive seen doctors for toenail paronychia on two of my toes throughout the years, and each time theyve given me a new diagnosis and course of therapyand none of these expensive impressions were successful. Things are going nicely now that Im taking this phototherapy device. It is fairly simple to apply and seems to be drying the paronychia and the nail at the same time. Its one of the only treatments Ive used that has at least somewhat changed the appearance of my nails. Jillian Henderson used this product 5-6 times the first day that I received it, and when I woke up the next day I thought I was loosing my mind with the change. The difference in one day was evident the thicker nail was lightening in color; 100% due to this device. Im about 7 days in and its unbelievable how clear my toe is. It appears to have killed the fungus, allowing my nail to grow. If you try it, use it more often than on the instructions you will be pleased! No oil or other ointment, just use this device!!! Ive only charged it once; I have it on now as I type this review . Hopefully Ill be able to wear sandals in August!!!

Thereby solving nail pain and swelling, eliminating pus or pustules, inhibiting foot itching, peeling, thickening of nails and other problems. Infrared cold laser is a medical and rehabilitation technology that uses infrared light generated by infrared lasers to treat pain and promote tissue repair. Generally, the wavelength range of infrared cold laser is between 650 nm and 1000 nm, and the most common wavelengths are 808 nm and 905 nm. In infrared cold laser therapy, infrared light produced by a laser is directed at the area of pain or injury. The infrared light is able to penetrate the deep layers of the skin and enter the inner tissues. These infrared lights have biophysical effects in the tissue, which can promote cell metabolism, increase cell energy production, promote blood circulation, completely remove inflammation and infection in the paronychia area, and strengthen tissue repair and healing.
