Im going to Mexico in one month, but I take acne medication and will probably need help from you about what to use. My face is 99% clear (I get a pimple every now and then) but my chest and back are still problems. They feel pretty smooth, but not so good, because the red marks are so prevalent.

Here s what I am:

Tazorac 0.1% cream, night: 7 days a week, morning: 3-4 days / week (so every other morning)
Trimrepthopen (twice daily) – a species similar to Bactrum
