I have pigmentation on my face and I am 19 years old. Pigmentation is not too much on my face but it is on my face which results in look my face uneven. I have uneven skin tone also and my great problem is I was having really fair skin but now after 2 years my skin clr has changed from the fair skin tone to medium skin tone. I don't know how it is but my skin clr is really changed, earlier my skin clr was really fair and have a dark circle also. Please suggest me some measures and medicated cream which is free from dangerous chemicals.
