Scars of pimple n hair fall. Hair fall!

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. The severity of acne dictates the choice of treatment. In the early grades of acne even the cream might suffice however in moderate to higher grades tablets also need to be taken. The treatment has to be continued for a few months otherwise the pimples would tend to return easily. Kindly do not self medicate without professional advice as that could further damage your skin.

There are various treatment options available for improving hair loss- apart from medical management other supplemental procedures like microneddling and PRP which can be used to achieve good results. When you mention about the scars do you mean the dark marks OR the depressions in the skin surface which occur when big acne pimples heal. For the treatment of the pigmentation marks creams can be used. For the treatment of the depressed scars procedures are required to get an improvement. There are options like hyaluronic acid filler or subdermal fat transplant which can be done for the holes if they are slightly bigger. But the very tiny depressed scars would require either laser treatment or micro needling. You could consider doing CO2 laser or Er:Yag laser sessions ; 5-6 sittings to improve the skin texture (upto 60-70% ) over the scar and the result from this will be PERMANENT. For the black marks you can try applying kojic cream for a month which will decrease the pigmentation on the marks. But for the holes some kind of procedural intervention definitely be needed.
