[/INST] Welcome to Chat Doctor Good Dayton need to confirm with the Dermatologist as to what is the problem in your skin. For severe acne with nodulocystic variety Cationic acid cream is the best. Do avoid sun exposure to your face.  Chat Doctor.  Eat fresh green leafy vegetables every day. Visit your Dermatologist and request the medication for the specific problem and also chemical peels are available. Kindly do request these in this regard. </s>
