Can retinol or AHA/glycolic peels cause old moles to regrow?

silvermoonlightDec 22, 2015
In the past month, I have seen the reappearance of three small, benign, black, flat moles (freckles) that I had removed 10-14 years ago. They were surgically excised and the wound stitched up. In reappearing, they are not as dark as they were before, but are definitely noticeable. In the past 6 months, I have begun using retinol and AHA daily or twice daily. I do a glycolic peel (30-50%) maybe once every 3 months. Could any of these have caused the mole cells to regrow?

When you shave and then apply acid it goes in much deeper and can be a problem. For now, apply Vaseline on moist skin to remain on as long as possible at night and apply 1% hydrocortisone twice daily. in the future i suggest you have a medical professional do your peels instead of doing them...

It will take at least a month and perhaps 6 weeks to notice any change although you dont say what you are looking to achieve.  It will be subtle but keep it up and it will continue to improve with time
