Olay Total Effects 7 in 1 instant Soothing serum

When i tried the Olay total effects cream last year i got a sample size of this serum along with it.I tried it and was pretty impressed with the results.But for some reason i never got around to buying the full sized product till now.

 

This is supposed to be anti aging instant smoothing serum.I use it under my night cream / moisturizer.The plastic pump bottle contains 50 ml of product , which theoretically should last up to a month with daily use.
