The short answer to that question is no, intense pulse light is not safe if you have a suntan; however, it does partially depend on what treatments and what correction you are requesting. If you are interested in treating pigmented areas on the face, then I would consider it an absolute contraindication to treat someone with intense pulse light that has a suntan. However, if you are mainly interested in the vascular component or if you are using intense pulse light for a deeper treatment such as Skin Tyte for skin tightening, you should be able to have a treatment performed even though you have a suntan. Obviously the correct answer to this question is you want to avoid excessive sun exposure and I highly recommend use of a sunblock on a daily basis to avoid the negative aspects of too much sun.
