Dianette is the only pill that cures acne completely as it works in a different way to most contraceptive pills - it blocks the androgens. But statistically it is the worst pill for DVT. Having said that, the risks are low anyway, and even with my migrainous neuralgia and continued use of Dianette, I never suffered any probems. If you get a scipt within the next couple of days, the acne should be cleared up in time. As for the blackheads... don't squeeze, use biore strips. You won't cause scarring and you'll remove far more that way. In fact, if you cleanse, exfoliate, steam and then apply the strips, they should be even more effective. Hope this helps X
