Didn't do Much For Me [SEP] I've used this serum several times and I can't say I noticed any "tightening" or any smoothness occurring.  It looks cool in the bottle being gold-ish with sparkles, but it did little to help my face feel moisturized.  I have to go over it with a good moisturizer.  The little beads rubbed in o.k. but again, nothing really happened.
