"mild stinging definitely occurs, i felt like i had a sunburn the first few weeks of using this.  also, my face was super dry as a result of this medicine.  on the bright side though, i did see improvement within 2 weeks and that&#039;s what counts.  so just get a thick moisturizer to reduce the stinging and the dryness and apply about 10 minutes after letting the benzaclin soak in, then you&#039;ll be all set."
