Review title is Nasty Looking and Nasty Smelling [SEP] The bottle looked like it had leaked when it arrived (photo 1).  I don't know if that damaged it, made it bad? I don't know.  However, the serum looked very thick and yellow (photos 2 and 3).  In addition, it smelled awful.  I can't tell you if it "worked" or not because it smelled so bad that I couldn't put it on my face.
