Does laser hair removal scar/damage hair follicles? This question leads further to cancer.

Does laser hair removal damage hair follicles & affect your body's ability to sweat and remove toxins? I'm concerned in the areas of armpit and groin area where there are lymphnodes. If the body uses lymphnodes and sweat to help clear out illness, would scarred pores/follicles prevent the body to do what it should? Will if reduce its efficacy to remove toxins? Will the laser damage lymphnodes? If lasers don't affect it, does electrolysis damage? Is electrolysis a better choice for safety?
