I can appreciate your concerns and address them with our patients daily. We have had great eliminating brown spots with the PicoSure Laser with the FOCUS lens array. We normally recommend a series of 4 treatments, spaced about 4 weeks apart. This treatment is non-ablative and has no downtime. You will typically have flushed skin in the treated area for 0-2 hours. Because the laser does not damage the barrier of the skin, you can put on sun-screen (or make-up) immediately after the treatment and go back to work. After your initial visit, a typical PicoFOCUS appointment is less than 1 hour.
PicoSure works much more effectively than BBL for clearing brown spots. We recommend finding an experienced physician in your area. Treatment prices vary by market.
