"i was prescribed this alongside clindamycin and benzoyl phosphate gel to treat mild acne on my face. it was a dosage of 100mg for 30days. around two weeks in my acne had improved significantly but in came in another problem , hyperpigmentation. my face is currently 3 shades darker than the rest of my body. i went back to my dermatologist and she prescribed another antibiotic and told me to discontinue the doxycycline. the discoloration has yet to improve but its only been three days since i stopped the doxycycline. hoping and praying the hyperpigmentation will eventually fade. i wouldn&#039;t recommend doxycycline since i believe there is a better more permanent solution for the treatment of acne"
