You said you have acne
on forehead,nose and between eyebrows( glabella).
And you your skin is dry, probably on trunk and extremities.
Your skin on face would be little oily.
And that's why you develop acne.
Apply clindamycine gel on lesions.
Take antibiotic like minocycline
or azithromycine ..for long time.
Cleanse the face with antiseptic face wash.
,avoid exposure to sun and pollution.
Avoid milk and oily food.
Take proper sleep.
You might be alright.
I hope you got my answer.
