Thanks for writing to us.
To treat acne, one requires to use topical creams like clindamycin, benzoyl peroxide
,,adapalene, tretinoin etc. If required oral drugs like azithromycin
, doxycycline and isotretinoin
can also be started. As you have acne over face, shoulder and back, you will need both and for the same consult a dermatologist
As far as constipation is concerned,
drink lots of water
Take food rich in roughage like fruits, salads, rotis with bran etc.
Exercise or walk regularly
If required you may try taking isapgul powder( psyllium husk) or lactulose syrup to relieve constipation
Hope that helped.
