Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain acne can occur due to a number of causes like oily skin,hormonal changes, clogged pores, bacterial infection, inflammation and excess sun exposure..
You should start washing your face with
Salicylic acid containing facewash.
Apply gels containing
benzoyl peroxide and
clindamycin..
Apply retinoid like Adapelene gel at night.
Do cool compresses over the pimples..
You can also scrub your face and other area using a gentle face and body scrub..
For scars you can apply silicone gel and creams containing azelic acid and
glycolic acid..
If there is pigmentation Kojic acid cream can be applied along with Vitamin E gel..
You can also go for treatments like
Microdermabrasion, chemical peeling, Fractional CO2 lazer etc..
Hope this information helps..
Thanks and regards,
Honey Nandwani Arora.
