Hello dear,
Acne are caused due to a combination of 4 factors:
1. Increased production of sebum from sebaceous glands in the skin
2. Increase proliferation of cells & blockage of these glands
3. Inflammation.
4. Bacterial infection.
The treatment depends on the severity.
Usually we recommend a combination of treatment with topical
retinoids at night and application of
benzoyl peroxide gel on the
pimples in the morning.
If the severity is more, antibiotics like
Clindamycin or Doxycycline are recommended.
Avoid oily foods, drink lots of water & clean your face with an oil free cleanser three times a day for reduction of pimples.
One more thing, please do not get influenced by advertisements of medications and creams which claim to cure acne. They may cause more harm than benefit.
Wishing you a good health.
Take care.
