I'm 52 with fair skin and I have brown spots on my face from too much sun exposure years ago.I was told that all I needed was two IPL treatments to get rid of the brown spots. I purchased a package of 2 IPL's and 2 Peels along with microderm treatments. I had two IPL's for the brown spots. I had the two peels and microderm treatments. The first IPL treatment brought up the coffee-grounds type discoloration. Then the coffee-ground appearance became lighter and eventually came off leaving my brown spots a little lighter. The second treatment did nothing at all. I went back a third time and they retreated the main spots and again nothing changed. Does this mean that they will never get any lighter? I also use a 4% hydroquinone product and tretinoin gel 0.05%. I use an SPF 50 sunscreen and avoid the sun as much as possible. Am I missing something? Should I have more IPL treatments?
