Has anyone successfully tried a skin lightener? My derm gave me a sample of TriLuma and it helped a little. I have a dark triangular mark on my cheek. About 7 years ago a different derm used laser on a broken capillary caused by my rosacea and now I have this dark mark. TriLuma is incredibly expensive and, of course, not covered by insurance so I was wondering if anyone has had success with a different product.
