In the past couple yrs I have noticed that I have pink blotches on both sides of my cheek area. In some areas you can see that I have large broken vessels in my cheek area. I've notice when I get sun on my face it's tends to turn darker and darker, it becomes a brownish color also above my lip it will tend to get darker (no pinkness above my lip) I have seen two Estheticians. And to be honest they don't sound real confident that it's one or the other. I recently started using tretinoin.
