Lynk-Gel method?

 The world’s first and safest LED-curable lash extension method. Lynk-Gel is a patented lash extension method that instantly bonds in seconds with the innovative Lynk-Gel device used with Lynk-Gel adhesive. The wavelength of the LED device measures at 401 nm (nanometers) and falls into the visible light spectrum. So what does that mean? UV (Ultraviolet Light) designates a band of the electromagnetic spectrum with a wavelength from 10nm to 400nm. UV radiation is present in sunlight. Nail gel lamps have wavelengths from 350-365m (UVA). Tanning beds have both UVA 95% and UVB 5%. Light “visible light” is defined by having the wavelengths from 400-700nm. Lynk-Gel’s LED is in the visible light spectrum at 401 nm.
