I am 29 years old lady and I am having pigmentation for 6-7 years. It was there on my nose now it has spread around my chick .I am trying to put some natural product (mixture of coconut oil, alerovela gel, vitamin E and sunscreen during day time) to get rid of it but it does nor go it become light for a while but does not clear at all. But other part of my face looks shiny amd healthy. Only pigmentation does not go. Kindly provide me with a treatment for good result.
