Thanks for your query.
Acne can present in several forms.It might be comedones,papules,pustules,or nodules.
You need to review your treatment from time to time with your dermatologist
The treatment always depends on the type of acne you have.From what you mention, it looks like you have pustular acne
as well.This usually requires antibiotics( oral).
Deriva CMS is a good medicine, you may continue it till you can visit your dermatologist for further advice.However, if you are facing any discomfort due to it , you should stop it.Sometimes , due to dryness of skin caused by this ,skin irritation may occur.
You can also get the come done extracted from time to time ti prevent them from developing into papules/pustules.
Hope this is helpful, take care!
