I have some prominent brown spots from the sun and wanted to see if this product would diminish them. Dermabrasion and other over the counter preparations have not been particularly helpful. Since I was unfamiliar with the product, I diluted it with water to a 50/50 mix and used it once a week for four consecutive weeks, starting with two minutes of application time and increasing to five minutes. So far, so good. The spots have faded although they haven't disappeared. The product certainly burns and reddens the skin so I'm not likely to ever go beyond five minutes or use the product full strength. Achieving good results gradually while maintaining a margin for safety is my strategy. The product comes with a very detailed instruction sheet that is enormously helpful in preventing overly aggressive application and accidental burns.  Read Less
