The type of device is not important, the wavelength/ spot size and settings with an experienced provider is. I recommend that you not make a decision on price alone.
Most providers follow the industry standard wavelength for lighter skin types with dark hair is 765nanometers (nm). For darker skin types it's 1064nm also known as a YAG wavelength. Best of luck, Doc Halliday
Both lasers will remove hair. I use the LightSheer Duet laser which has a large hand piece with a vacuum for fast, comfortable treatments.
In my practice I use diode lasers for the best outcome. I typically have patients do every 4 weeks for the first 3 times and then every 4-6 weeks for 3 times after. It takes a series of treatments for improvement in hair reduction. I suggest you see an expert. Best, Dr. Emer
They aren't exactly the same. The Lightsheer Duet is considered by many to be the gold standard diode laser for hair removal. It's vacuum adds more comfort, more safety to the treatments. It is a very quick procedure as you know. The Elos plus adds radiofrequency to the pulse and reports this gives better efficacy. I have not seen that this technology improves hair removal. I would think it would add to discomfort and it would be slower.
