Consistency is the key!!! Ever since I got my nood laser I followed the instructions. Went to do a patch test waited 48hrs or probably over that just to see if i’m gonna have any bad reaction from trying it and nothing!! So I started it with my legs and did it twice a week. 1st two weeks of using it,you’ll already see that the hair grows slower !!! And after a month there are only spots in my legs that still has tiny bits of hair. I recently went on a vacation, I did my laser the night before my flight and for 5days I had smoother legs !!! I would really highly recommend this product and the price is more economical than the other ones out there.
