How long and at what dose were you using the accutane? Have you used accutane before?
I know about it. Problem with isotretinoin ( retinoin too ) is their degradation - light degradation. Our first sachets of iso. was not opaque and after some time they probably lost function ( or most of it )
But this problem was solved in past and guys who claimed some issue received pharma grade Iso. like compensation.
Looking like not all of them wrote me about it.
