You are having hypermelanotic macules and patches on face.
They may be either postinflammatory hypermelanosis
I would not advise for laser treatment
The color may gradually fade after simple measures.
Take orally glutathion ,vitamin C and nicotinic acid.
Rub kojic acid and vitamin C containing cream.
Cleanse the face with kojic acid and glycolic acid
containing face wash.
Avoid sun exposure.
Be calm, avoid anxiety and tension.
I think, you will get good result.
However , you consult dermatologist
I hope, you got my answer.
