Would vitamin C cream help target hyperpigmentation caused from sun spots? (photo)

Hello doctor, I suffer from pigmentation in my back from the effects of the old sun. I also mean from coffee spots with milk, as in French. I used a chemical peeling at a doctor, but it left fire marks on my body and the pigmentation increased. I used Kligman’s formula, but it relieved them a little, but I still suffer from pigmentation. What do I use? Another cream to get rid of pigmentation, I heard about c, is it really good?cyspera creme
