Thanks for your query.
for acne my advice would be
-Do not squeeze or scratch the pimples.
-Keep your skin clean,Have healthy diet & lots of fluids.
-Avoid too much oily foods.
-Apply topical Clindamycin
gel over the pimples
-You can use topical tretinoin over the comedones [ be careful,burning sensation & redness
occurs often after applying]
- if have you are having too much of nodulocystic acne
you can use oral Isotretinoin
for 4-6 months [but always under supervision of your dermatologist]
Hope this helps you.
Stay in touch with your dermatologist.
