Hello and thank you for your question. Intense pulsed light (IPL) treatments, also referred to as photofacial rejuvenation, can effectively break down and eliminate unwanted skin pigmentation. Fractional radiofrequency (RF) treatments can also be used for similar results with a quick recovery.Which type of treatment is best for you will depend on an in-person evaluation with a board-certified plastic surgeon. During your consultation, your doctor should be able to determine the type of blemish you are hoping to eliminate and choose the best treatment for the job. Hope this helps!
Photos would help here! It's hard to say which laser is best without knowing what type of "brown spots" you are describing. IPL would be the most general answer, but it depends again, on what type of brown spots they are.
