I've tried the new version at the counter and apart from the container it appears to be the same as the older version. I had my bottle for ages and the reason why I still have it, is because this base has a very thick texture, and personally I would prefer something lighter.
I can only use this when the climate is really dry, and on those days I do like the effect, it evens out my skin tone with a bit of coverage. For each application you'll only need a tiny bit of product, about half a squirt, and it's kind of hard for me to control the amount because I have it in a pump, but since they have change the container I guess that it would be easier to control the amount now.
I got this in yellow, because at the Ipsa counter they have this computer where they'll test your skin and according to the results I was recommended to get this in yellow. If I had to buy it myself, I would never have got this in yellow, but the recommended shade really did even out my skin tone, therefore, if you are interested make sure you do the test before you get it.

我這支妝前底霜已停產，新版叫 Pure Control Base，而小妹亦於專櫃試過，個人認為除了包裝外，和舊版沒有什麼分別。
