I've brown marks on my face as a side effect of Cymbalta.. I've been on Retin A for 3 months now and I've seen no improvement. Furthermore, I live in a very hot country and I've been advised by the dermatologist to stop using Retin A at the end of this montht. Is there a cream I can use during summer that can help with my brown marks? They are quite unsettling and I've resorted not to go out of the house because of them.
