"i used this for one month with little to no results on my face; on my chest, it cleared up the clogged pores very quickly. i&#039;ll be switching back to epiduo, a stronger retinoid and less risky anti-septic (topical antibiotics pose the risk of creating antibiotic resistant bacteria). after seeing that most of you experienced notable improvement within a month, if not a few weeks, i&#039;m forfeiting this treatment."
