Which is best for acne: Tazorac cream, Erythromycin topical gel, or Erythromycin & Peroxide Topical Gel?
Also, all of them have been expired for over a year. I have kept them stored properly, including keeping the Erythromycin & Peroxide Topical Gel refigerated. Would it still be okay to use them and what side effects could occur?
