Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain black spots on face left after healing of the pimples seems to be due to post inflammatory
hyperpigmentation and the black spots are hard to remove quickly and can take a long time to fade..
I would suggest you to start using topical
depigmentation creams and ointments like washing your face with
Salicylic acid and glycolic aci containing facewash..
You should apply creams containing Kojic acid,
glycolic acid and arbutin..
You can also apply Grapeseed extract, licorice extract and Vitamin E and C containing creams..
Exfoliate your skin twice a week..
You can also apply a gel based sunscreen lotion when exposed to sun..
You can go for treatments like
Microdermabrasion, dermal rollers and chemical peelings..
Hope this information helps..
Thanks and regards.
