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!!! Timothy Callen Oveallgo Revolutionary High-Efficiency Light Therapy Device usesblue light therapycombined withinfrared cold laser technologyto effectively eliminate fungi, inhibit inflammation, and prevent infection. Thereby solving nail pain and swelling, eliminating pus or pustules, inhibiting foot itching, peeling, thickening of nails and other problems. Blue light therapy is a medical method that uses a specific wavelength of blue light (470 nm) to treat nails. In blue light therapy, the patients nails are exposed to blue light with a wavelength of 470 nanometers, which penetrates the surface layer of the nail and produces a photodynamic response to the keratin in the nail. The photodynamic reaction causes keratin to combine with oxygen molecules to form toxic oxygen radicals that damage or kill bacteria and fungi around the nail. Moreover, blue light has an antibacterial effect, and can also reduce infection caused by inflammation, relieve redness, heat, and pain symptoms at the inflammatory site, and fundamentally repair damage without side effects and drug resistance.
