is a multifactorial disease.
It generally occurs in teenagers having oily skin diathesis.
,excessive sun exposure..etc may exacerbate acne.
Drugs like iodine and isoniazide may lead to acneiform eruption.
Cosmetic acne may be there.
I would like to recommend azithromycine 500 mg daily in morning and cap isotretinoin
10 mg at night till you get good result.
gel at night.
Cleanse the face with acmed face wash thrice day.
Take good sleep,avoid stress and avoid oily food and milk.
You may be having good result after 6 months, even after good result you may maintain treatment up to 2 years.
I hope you got my answer.
