Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain pimples or acne can occur due to a number of reasons like hormonal imbalances, oily skin, excess sun exposure, bacterial infection, inflammation etc..
I would suggest you to wash your face with
Salicylic acid containing face wash..
Apply a combination of gels containing
Benzoyl peroxide and
clindamycin..
Apply Adapelene gel at night..
For darkening of skin apply Kojic acid and arbutin containing creams..
You should exfoliate your skin twice a week with a face scrub..
Take Vitamin C supplements..
Apply Vitamin E gel at night..
Avoid oily food and excess sun exposure..
Drink plenty of water and take nutritious diet..
You can also go for
glycolic acid peeling and
microdermabrasion..
Hope this information helps..
Thanks and regards.
