The other best options for your problem are Oral antibiotics
, Oral retinoids, Fraxel laser,Laser Skin Resurfacing
,ProFractional laser,IPL,Piexel or Pulsed Dye Laser.I have seen lot of pts who responds to oral antibiotics(Tetracycline,Erythromycin
,Clindamycin,Minocycline or doxycycline)along with topical medictions.Retinoids are the next best options but there are certain protocols to follow before starting on oral retinoids as they are teratogenic.A complete blood work up,LFT,Lipid profile
,pregnancy test..have to be done.And this have to be repeated every month through out the treatment period.
I suggest you consult senior dermatologist
and cosmetologist as it is dificult to suggest one particular treatment without analysing the type of acne and scars that you have.
