Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got post-inflammatory
hyperpigmentation due to which there are dark spots on face..
As you also have pimples occuring every month the treatment will constitute of both anti-acne as well as
depigmentation..
For acne you can wash your face with
salicylic acid and
glycolic acid containing facewash, apply a combination of
benzoyl peroxide and clidamycin containing gels, do cool compresses..
You can also apply retinoid containing gel like Adapalene gel..
Exfoliate your face with a gentle scrub twice a week..
Limit sun exposure..
For pigmentation you can apply kojic acid, glycolic acid and arbutin containing creams.
Take vitamin C supplements.
Apply a sunscreen lotion when exposed to sun..
Drink plenty of water and take nutritious diet.
Hope this information helps..
Thanks and regards.
