feels nice on, no amplifying properties noticed though
I did not notice or observe any change in volume as advertised, whatsoever.  The serum is very thin and although it feels temporarily conditioning or smooth, it wears off quickly, and the conditioning properties equate to that of a vasolene type substance.  Lip 6x serum left me with the impression of a very low quality, inexpensive (although not cheap to purchase), forgettable product.  I can not recommend this product for the attributes advertised.
