my favorite product [SEP] the first two or three days i used it all over my face i had a very mild breakout and corner of my nose was a bit sensitive for this reason i started to use niacinamide only the areas with enlarged pores being my nose and top area of cheeks i did try using on my entire face and neck after a few days again and had no problem i believe my skin just needed to get use to this product after applying niacinamide over face and neck i apply cerave moisturizing cream i use every night sometimes during the dayafter a few days of using this product my skin looked the same but felt very soft and smooth after about a week skin still felt soft and smooth and began looking brighter just healthier looking after just over weeks my enlarged pored stared to look a little tighter after a month i decided i loved this product my pores never looked better and i don t have that dry stinging feeling you get with retionol a little goes a long way with this productthe product itself is water bases so it absorbs well and further blurs any blemishes including pores when on the skin a little goes a long way you only need a few drops the reason i purchased this product was to use for my enlarged pores but i am very happy for the additional benefits
