My esthetician treated me with Deep Fx about 2 months ago. Would it be okay to begin using Epiduo again, or will that inhibit my skin's healing? I used Epiduo in the past to control my comedonal acne. After getting Deep Fx, my esthetician sold me onto his Environ vitamin serums, but they have been ineffective in preventing my acne. I'd like to swap out the vitamin/retinoid serum for Epiduo. Or could I use both in conjunction? I'm 18 if that matters. Thanks!
