Hello, I completely understand your concern for pimples. For a female it is really distressing if there is presence of pimples on face and that too at teh age of 29 years. There is the most important role of high oil secretion and therefore an increase the size of oil glands especially. As the pores or ducts of the glands are blocked so it leads to formation of pimples. For married females the safest of all is a weekly course of oral Azithromycin 500 mg for 3 times a week can be taken for 2 months. I generally prefer to give a gel containing Clindamycin with Adapalene in it. This should be applied at night time in thinnest possible amount over pimples only. For initial few days apply for 1 hour and then wash it off. Kindly avoid any home remedies suggested by your friends or family members. Take further guidance form a dermatologist. Alll teh best.
