Hi, thanks for your query.
You seem to have acne over your face, chest, back.
Acne develops when there occurs excess of sebum production which collects in the pilosebaceous duct and leads to formation of black heads and white heads. As it progresses further, there occurs formation of red raised bumps or pustules.
It is these white heads and pustules when you squeeze out white and yellowish material respectively.
You may apply clindamycin
and benzoyl peroxide
combination cream over the lesions at night.
You may take oral azithromycin
by consulting a dermatologist.
Once acne is under control you may start treatment for open pores in the form of chemical peels
and tretinoin cream at night.
This will help in controlling acne as well.
You may consult a dermatologist
for examination and best possible treatment according to your skin.
Hope this helps you.
