forget the brand or type. Whats important is the wavelength of the diodes, and the power of them. laser combs usually have 9 x 650nm(wavelength) 5mw (power)diodes. some only have one reflected into 9 with mirrors.
clinics use 100+ of these same diodes. Im not saying it works, because i honestly dont know, but if u want to give urself the best chance, and get the same treatment that costs thousands at clinics, then get a device with 100+ 650nm, 5mw diodes. a device like this will cost between 500 - 1000$ the diodes only cost 3$ each, so its also easy to make one urself. Ive done it myself, but i got lazy with it and sold it.
just to clarify, i really wont get drawn into a debate about whether or not laser treatment works or not, evidence is pretty anecdotal.
just saying he can get the same treatment sold for thousands in a clinic for cheap, rather than paying 700$ for 9 x 3$ diodes. Im just trying to save the man some money.
one thing for sure is a lasercomb will do nothing.
