Brown Hyperpigmentation after upper and lower eyelid lift and resurfacing. Once healed can The Hyperpigmentation come back?

Hyperpigmentation after upper and lower eyelid lift and what I thought was a light resurfacing in the operating room. I had this procedure done in Florida (I live in PA) on the recommendation of my sister. He is a board certified plastic surgeon from Melbourne Florida . 25 days later I hyperpigmentated. Went to see the doctor who put me on 6% Hydroquinone, Trenton 0.025%, vitamin c serum and moisturizer. It’s been 9 weeks and the browness seems to be gone. Once healed will the Browness come back?
