Hi, As you said you suffer from pimples, also called acne vulgaris. There may be different types of lesions in this disease like white comedones,black comedones, inflammatory lesions,cystic and conglobate acne..etc. The lesions may be precipitated or excerbated by stress,anxiety,sleeplessness,drugs like steroids, hormonal imbalance,dandruff,oily food..etc You have PCOS,you may continue treatment. I generally treat my acne patients explaining about long term treatment and to avoid anxiety related with treatment. Antibiotics like azithromycine or minocycline in proper dose may be taken. Isotretinoin in low dose 5 mg may improve the lesions. Clindamycine with benzoyl peroxide 2.5 % may be applied on the lesions at night. Antiseptic facewash may be used to cleanse the face. Patience is necessary to get relief. You consult dermatologist for firm diagnosis and treatment. Thanks. Dr. Ilyas Patel MD
