I have been using Kiehl’s Super Multi-Corrective Eye-Opening Serum for two weeks now. I am happy to report I do not notice the slight burning sensation I experienced when I started this product. It does feel as though the skin around my eyes is firming up a bit. This has however, not translated into any visible improvement. I know my pics aren’t the greatest but judge for yourself. Holding thumbs for a visible improvement in the coming two weeks.
