whats the deal with the hype of this avoid [SEP] okay so i received this about weeks agofirst impressionsi had been using it twice daily after cleansing toning and my essence i am used to using a serum but this product seriously made my face super red every time i applied it i assumed it was due to a niacin conversion on my skin but after a couple weeks i started breaking out more than ever i noticed that my skin was completely sensitive red and everything would sting my face i did not think it was this product at first but after i stopped using this product completely the redness and sensitivity stoppedconclusion do not buy this product in my case this product made my skin worse than it has ever been along with being super crazy sensitive i do not recommend this to anyone but perhaps i received a bad batch the lot manufacturing stamp on the product is if anyone with the same lot manufacturing stamp is having a similar issuehowever if you are looking for a niacinamide zinc formula i would recommend revolution skincare niacinamide zinc from ulta instead i have now been using that for about weeks without any of the same issues from the ordinary
