I am south Asian and 18 year old female. I have had dark skin on my upper lip for 4 years! I pluck the hairs only (Photo)

when I was younger I had thick hair on my upper lip and was bullied. I spent 2 years trying to hide it by walking about with my hand over mouth (even during a conversation!) or biting my lips together which stretched out the skin to make it appear lighter for the whole day. During this period I had perioral dermatitis and colesaws. Having stopped that for about 4 or 5 years now I remove the hair but the skin itself is very dark. The skin is quite scaly but not dry. I also have sensitive skin
