Hello and welcome to healthcaremagic Laser hair reduction (LHR) is a very safe and reliable way for hair reduction. Coarse facial hair in females (Hirsutism) can be safely and effectively reduced by Laser. Apart from mild redness post-laser which goes away with ice-pack application there are really no side effects at all, if done by a well trained/experienced expert. However, before anyone undergoes LHR, it is important to know the cause of Hirsutism from history and lab investigations: --Your doctor would like to know whether there is any history of menstural irregularity or not? --Any history of hair loss/hair thinning from the scalp? Acne might be an indication of underlying hormonal abnormality . Judging from the history your dermatologist might ask you undergo the following blood tests to look for any underlying hormonal abnormalities: --Serum Testosterone --Serum DHEAS(Dihydroepiandrostenedione sulphate). --Serum LH/FSH --Serum Prolactin --Pelvic ultrasound for polycystic ovaries. Underlying hormonal abnormality if discovered on history and physical examination and confirmed by lab test needs to be simultaneously treated with Anti-androgen therapy whilst undergoing Laser Hair Reduction. Hope this helps regards
