Yes, it works in 3 minutes as it claims. Sunday Riley Good Genes All-in-One AHA Lactic Acid treatment comments hyperpigmentation, dark spots, fine lines and radiance ... and in under 3 minutes! You can visibly see it. I use this in the morning before vitamin C and moisturizer and then at night before bed. Get it at Sephora. sundayrileypartner ad sundayriley @sephora @sundayriley sundayrileygoodgenes sephora LTKover40 LTKbeauty LTKsalealert
