Thanks for writing to us.
It seems you are having comedonal acne( whiteheads) . The same can be treated by taking low dose isotretinoin
orally along with application of tretinoin or adapalene
gel. Isotretinoin should always be taken under a doctor's supervision and guidance as certain precautions have to be taken while being on it. As these are prescription drugs , I would advise you to consult a dermatologist
near by. You can also take few sessions of salicylic acid
peels for better results.
Hope that helps.
