What is the best device for laser hair removal for Asian skin/hair?

Diode, alexandrite and yag lasers work best. It will take a series of treatments to get improvement. Please know that it will take a series of treatments to get improvement. I typically have patients do laser hair removal every 4 weeks for the first 3 sessions and then every 4 to 6 weeks for the following 3 sessions. This schedule gives great results with hair removal. Some patients do require treatments to maintain results. See an expert for an evaluation. Best, Dr. Emer.

Hello, I would need to see your skin in person to accurately answer this but generally I would use an NDyag laser on Asian skin.  Laser hair removal treatments do not lighten your skin.  You can address pigmentation with other lasers or you can use a cream with hydroquinone.   I would also recommend treating your PCOS before starting treatments as hormones can cause continued hair growth.  As far as treatment costs this varies greatly by area.  A lot of places offer consultations free of charge and can discuss treatment options best for you as well as cost. 

Great question! Laser Hair Removal is to help reduce hair growth and depending on how thick the coarse of the hair is you might need 6-8 sessions. Anything after that you can get touch ups every so often. Vectus laser by Cynosure 810nm has amazing results. Hopefully this helped, wish you the best of your treatments.

Virtually every laser hair removal machine has settings for different skin colors.  Find a board certified cosmetic dermatologist who you trust.  A series of treatments will be needed, approximately six over the course of about 8 months. 

Asian skin tone is a challenge for hair removal with a laser mainly because the skin may look fair, but pigment deep in the skin will absorbblaser light and can become discolored. For this reason, we have invested in Venus Concept devices which use intense pulsed light technology to remove hair in most skin types. The cost is comparable to laser and is dependent on surface area to be treated. Like laser it takes up to 6 treatments to reach maximal results.
