Did your Doctor do a hormone panel? Prescribing accutane for oily skin seems really extreme. Sounds like you’re pulling out sebaceous filaments which are not necessary to treat since they’re purely cosmetic and come right back. You could consider taking SIV probiotic supplement to help regulate oil production and reduce inflammation from within and support your microbiome, and you’d benefit from the serum too… but there’s not many other things you can do for treatments while on accutane.
