How it works
E-light pairs two energy sources that do different jobs. The IPL side follows the principle of selective photothermolysis: filtered broadband light is absorbed by pigmented targets, chiefly melanin in hair follicles and lesions, and haemoglobin in visible vessels, which heats those targets faster than the surrounding tissue can conduct the heat away. Anderson and Parrish described this mechanism in 1983, and it still underpins how these devices are dosed today.
Where the MF-05 earns its keep is in how you shape that light. Swappable filters trim the lower end of the spectrum, so a hair-removal filter starts higher up and spares more epidermal melanin, while rejuvenation and vascular filters open a wider band to catch both pigment and haemoglobin. Each shot can be split into a first pulse and a train of sub-pulses, with widths and delays you adjust per skin type. Those gaps give the epidermis time to shed heat between bursts.
The RF stage works differently. Radiofrequency current in the low-megahertz range excites water molecules in the dermis, producing heat that doesn't depend on skin colour at all. That thermal load stimulates collagen remodelling and skin tightening, and it lets you dial back optical fluence on darker skin without giving up clinical effect. Contact cooling protects the surface throughout. This is professional equipment, and results depend on a trained operator matching parameters to each patient.
