Kiehl's Iris Extract Activating Essence is one of the brand's major launches for the year - it's a brand new product, rather than an extension of an existing line, so that's pretty cool. According to the Kiehl's websites, the Kiehl's Iris Extract Activating Essence is an "essential 'first step' anti-aging treatment to maintain skin’s youthful texture, reduce fine lines, and activate radiance", and a "multi-action treatment essence for youthful, radiant skin".
If you're familiar with the concept of lotions (which have been very popular in Asia and beyond over the past few years), then the Kiehl's Iris Extract Activating Essence is essentially a similar product - basically, a light, watery lotion that you can apply on your face before heavier creams and treatments, like face creams and so on. Kiehl's claims that applying this lotion first "optimizes penetration of subsequent skin treatments", and I've seen similar claims made by other brands which sell lotion of their own.
As with all my other skincare reviews, this review starts off with the ingredients list, only this time, I've also managed to get answers from Kiehl's too, which is pretty exciting! Since not every brand is as open to answering questions about their products (especially questions like mine, which are more about the ingredients and formulation, rather than things like "is this better for oily skin or dry skin", which can be tougher to answer), I'm really happy and thankful that Kiehl's didn't shy away from answering my questions. In fact, I think they've got some pretty good responses, as we shall soon see!
