Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain dark or black spots left on face seems to be due to Post Inflammatory
Hyperpigmentation that occurs due to pimples..
You should
consult a Dermatologist and get evaluated and he can advise you to wash your face with
Salicylic acid and
glycolic acid containing facewash..
For dark spots apply creams containing Kojic acid, glycolic acid and arbutin..
Vitamin E gel can be applied at night.
Creams containing Grapeseed extract, licorice extract are also helpful..
Azelic acid preparations are helpful..
You can exfoliate your skin twice a week with a gentle scrub.
Take Vitamin C supplements..
You can also go for treatment like
Microdermabrasion and chemical peeling..
You can also apply a sunscreen lotion when exposed to sun..
Hope this information helps..
Thanks and regards..
Dr.Honey Nandwani Arora..
