I'm on accutane right now and you NEED joint supplements like Cissus or an all in one product like Achilles from AL. My bloodwork was always perfect and they even took me off the bloodwork for how good it was lol. I took Liv52 the whole way through so far and even up to now. I'm on my last month.
Anyways, what worked for me before my last cycle just exploded me was this:
Cetaphil gentle cleanser
Acne.org Benzoyl Peroxide - Use index finger length and apply evenly across your face and if on your back apply it there as well. BP works no matter what.
Acne.org Moisturizer / Cerave PM (used this in AM as well) - BP will dry you the **** out as good as sounds, it can cause your skin to be irritated and can produce more oil
I would try this kind of routine honestly, and the BP is extremely effective no matter what you just need more. Always go for a topical gel of BP 2.5%. Anything else is worthless. I used acne.org because I couldn't find any other BP like it lol.
