Kiehl’s super multi-corrective eye-opening serum was sent to me about two weeks ago by the fabulous staff from Beauty Bulletin. I received a number of sample sachets, which I couldn't put to immediate use as we were going camping and I was worried that the sachet contents would squish out into my vanity bag. I have been using this product for about a week and a half now. My first impressions were that it is non-oily and didn't leave a residue on my skin. I could feel the hydration of the product instantly as I applied it. Sadly, I haven't noticed any firming effects as yet, as I can still see the fine lines around my eyes. I am hoping that with continued use, I will see some firming effect and a noticeable reduction in the fine lines. I am posting my before pic, and holding thumbs!
