I have been on them for 10 weeks now at 3 tabs (60mg) a day. They are definitely working. My skin is normally very oily despite 2 showers a day (has been since I was a teenager) and now it is much, much less oily.
I started out with one tab a day for the first week to see when things would start to happen. It wasn't until I went up to 3 tabs a day (third week) until my skin started to dry out. Nothing intolerable (no my lips did not fall off), but I needed to drink alot more water than usual and keep my lips moisturized by using Blistex (in the white tube).
I tried Vitamin B5 up to 5-10 grams (5-10 1000mg tablets) and it worked up to a point with Test and Deca. When I switched to Anavar and Winny, the B5 did not seem to work at all. My back was starting to get a bunch of small zits and it was getting worse. I tried every suggested homemade remedy that everybody suggested (various astringents, drying soaps, alchohol/peroxide concoctions, tanning etc., etc.) and nothing seemed to work for me.
After about a month on the "Asian" accutane I saw noticeable improvement - better than anything so far. It is definitely the best thing I have tried so far - bar none. Some of the sides effects I have seen (and some of these could be psychological) were dry lips, increased thirst, some lethargy, decreased libido over a period of time, some muscle cramps and some general apathy that I don't remember having before.
If I had to do it over again, I would have used it earlier and not wasted my time or money on temporary/half-baked solutions.
Take some sort of liver detoxifiers - Liv52, Primrose Oil, etc while you are using the accutance. Take care and good luck.
