Trying it with other ordinary serums, wow [SEP] I always love the ordinaryAnd so far I’ve been using It for a few weeks now and I can see a big difference in my acne now. It’s awesome and I purchased a few other ordinary serums and I use them all my on my face before I go to bed. I wait in between each one about ten or 15 minutes to let it sink in my skin. Love them and acne and my large pores are getting smaller. Hope this helps!
