Hello dear,
Pimples 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 (like Isotrion) 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.
But these need to be taken under the guidance of a
Dermatologist to avoid any unwanted side effects.
Also avoid oily foods, drink lots of water & clean your face with an oil free cleanser three times a day for reduction of pimples.
Wishing you a good health.
Take care.
