Review title is Roller Ball May Not Be the Best Mode of Application [SEP] I've been using this serum for 5 days, AM and PM.  I believe I see some minor reduction in the lines under my eyes...but it could be wishful thinking.  I am not convinced there is always serum coming out while rolling it on because the nature of steel is that it feels cool to the touch, therefore can give the impression of depositing serum when, in fact, it isn't.  To determine this I ran it over white tissue several times; only about 50% of the time did serum actually come out.  I removed and cleaned the steel roller ball as directed then reran my "experiment" and had the same results.<br /><br />During application I can briefly detect a damp look where it is being deposited, but this goes away within seconds.  At other times nothing is on the surface of my face and immediate dabbing with a tissue proves there is no serum.  I am not convinced this is the best mode of application.<br /><br />If, after a couple of months of use, I see definite wrinkle reduction I will happily update my review accordingly.
