i have experiance with doxy
Hey there...
My derma had me on doxy for 6 months..it worked ok..but im not a huge fan of long term antibiotics...
He switched me to tretinoin (topical) but it was too harsh...and then to clindamycin 1% and also differin (adapalene)
stuff works awesome..i'm 29 and still deal with acne..its just one of those things in life
good luck!!
