"while pregnant with my 3rd child, in my early 30&#039;s, i began getting horrible acne, mostly on my chin. it was a combo of white/blackheads &amp; big cyst-like pimples and a lot of redness! how embarrassing &amp; painful. i seen a handful of physicians who prescribed different combos of oral and topical antibiotics, benzoyl peroxide, retin-a and who knows what else, but nothing worked. very frustrating! so after about 4 years of this (&amp; scars now) i finally seen a derm. who prescribed aczone (twice a day) &amp; tazarac (every night). these were winners for me! what a relief. it did take at least 4 weeks or so to see a big difference but my face eventually completely cleared up!!! the results outweigh the side effects (skin peeling mainly). worth the $$!"
