My practice is now offering Diolaze, a non-invasive procedure, that requires no down time for hair removal. A diode laser beam passes through the skin towards hair follicles. The penetrating energy then heats up the hair root, which in turn prevents future hair growth. This procedure has one of the largest treatment spot sizes with a built-in skin cooling surface which makes treatment more comfortable than other devices. The number of sessions will differ depending on your hair color, hair type, body area, and skin tone, but each session would probably require 15 minutes. Best results are noted after four to six treatments. Touch-up sessions may be needed as there is no way to rid the body of hair permanently.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA
