What happens if you get a laser hair removal treatment 3 weeks after a treatment?

Hi Shelle.  You can certainly have another treatment several weeks after the last one, but there are a number of concerns.  The first is that you mentioned you were not feeling the "sting" in the unresponsive area.  If your treatment does not involve some discomfort, you may not achieve good results.  This may be because the office is using the wrong laser for your skin type or because they are treating at a low fluence (energy).  At 5 treatments, you should expect to be at 50% - 75% permanent hair removal.  If you are not, then it may be time to reevaluate.  For examples of before and after photos of Los Angeles laser hair removal, click on the link below. 

Hi Shelle. There are certain things that can be done to treat stubborn hair that continue to grow after laser hair removal treatments. One is to turn up the energy of the device. Another is to shorten the time between treatments. What they are trying to do is to increase the likelihood that those hairs are being treated during the grown phase of their cycle. If you have any questions about the treatment you are receiving then you should talk with the physician who oversees the laser treatments at the facility. Hope this helps!

Its okay to get hair removal 2-3 weeks after the previous one.  There is no risk as long as there is no burn or issues on your skin.  Best, Dr. Emer.
