Talk to Dermatologist on Skin Problem

Basically I had chickenpox when I was around 11 years old but still now I've small holes of them on my face and second of all my upper face like is lighter and the area from my mouth whole chin jawline have dark tone basically uneven skin tone and it is dark. also I've very dry skin and in summer only my T zone area is oily you can say I've combination skin. And I suffered with dry patches below my dark circles and also bumps on that area and blackhead on my nose even though I don't use anytype of blackhead patches on my nose so this is my whole concern and I've uneven skin tone for a long time I've tried nicanimide, glycolic and vitamin c but nothing make any difference.
