Best Way to Cure or Heal Sun-damaged Facial Skin?

I am a US Latina citizen from Costa Rica. On a visit there a few years back, I recieved a severe sunburn that caused a big brown spot on both of my cheeks. I was taking the pill and did not realize to stay out of the sun. I have tried several things and several thousands of dollars, with no improvement. I have had chemical peels. Will Vi Peel work for my problem? What is the best solution for sun damage on the face?
