Hello and welcome to HCM Laser hair reduction (LHR) is a very safe and reliable way for hair reduction. Apart from mild redness after the sitting which usually resolves in 1-2 hours, there are really no side effects at all, if done by a well trained/experienced expert. Normally 6-8 sittings will give you a good hair reduction. The hair will become finer, the density will decrease and thereby greatly reduced. It is the FDA approved for hair reduction and gives long lasting results. Creams containing ingredients like efflornithine hydrochloride work by inhibiting the hair metabolism thereby reducing the rate of hair growth, but they won t permanently get rid of unwanted hair. They only slow the hair growth rate. Regards
