@taohyun: #stitch with @jeffreestar the product itself sounds amazing, perhaps even better than the #fresh strawberry cleanser? Who knows. . Anyways, glycolic is arguably the harshest of all AHA’s vs. lactic acid which is arguably the most gentle. . So hearing this was a bit confusing. Glycolic can be very irritating at times depending on the circumstance and product. #jeffreestar #glycolicacid #ulta #sephora #esthetician
