I was wondering - is there a chance Keren changed the vitamin C serum, even a tiny bit?
I purchased it two times a while back and it was wonderfull and completely changed my skin's appearance, but the third time, which was a few weeks ago, was kind of different.. it feels like the serum is not the same and it tightens my skin so it feels a bit dry (which never happend before).. what could be the reason for that?
thanks
