Hello , 42 Years Old Male . I Have Melasma

Hello , 42 years old male . I have melasma for about 2 years , and I did chemical peel but it seemed to be even darker . I recently had derma roller and seemed to work better . My question is, my dr treated my acnes when I was teenager with doxycycline and it worked very well. can doxycycline be used to treat melasma? Thank you
