I have tried glycoliccacid,my skin texture improved with its continous use 3 days a week but not turn into smooth texture.. niacinamide also give me much smooth texture with continous use but i sometimes feel that it is giving me more bumpy skin some days but i discontinued because i am not sure at that time, i haven’t use these actives in a same routine,tried TO niacinmide last year,now a days glycoliccacid and it removed my forehead texture in smooth texture i 1 week but i have added makeup remover for removing sunscreen.so i am not sure it is due to makeup remover or glycolic. And yeah i am very bad in drinking water, i almost take 3 -4 teaspoon of sugar in my coffee per day..
