I finally saw it at Walmart, there was only 2 left. You get 0.85 oz for Cad$9, not bad. This is a silicone ladened primer, which works for me. The so called "slightly pin" colour is a joke, consider it as colourless. I literally put some on a white paper & I did not see a tinge of pink on it.
I cannot use liquid/cream foundation without (silicone) primer, it enables me to spread the fdn evenly & smoothly. The primer goes on after the moisturizer, then I have my morning tea, afterwards, all are absorbed (dried).
I cannot comment on the pore issue since the fdn/powder takes care of this pretty effectively.
I often blend various shades of fdn or concealer in a small pot, then add some silicone primer as a medium, voila, custome-blended fdn.
At the moment my favourite blend are various shades of Dermablend's leg & body with primer. Fantastic.
