Highly tanned face. Tanned. kindly help!

there can certain medications that increase photosensitivity but then it should be restricted only to face.. hence I think the anaesthesia is less likely... There are multiple causes for facial hyperpigmentation. Sun tan, overweight, pigmentation disorders like acanthosis nigricans or melasma, lichen planus pigmentosus, rhiel's melasnosis, nutritional deficiency etc are some conditions. The patches of pigmentation need to be examined and assessed to know the cause. Treating it without knowing the underlying cause will offer incomplete and temporary relief; also it will keep rebounding. You should send me images through private online consult for a better assessment of the problem and approaching it accordingly. I practice in mumbai itself. You can meet me and get it properly assessed if you wish. A direct consultation would always be preferable to an online consultation.
