Lash Roche Posay Hyalu B5 Eye Serum...I've tried a lot of serums in my time, some have worked better than others, some haven't worked at all. So there was part of me that thought "here we go another serum that probably wont work" BUT after only using for a week the results really are clear to see (see photo) and I'm genuinely amazed at the results, as a menopausal lady I've kind of got used to having puffy, dark circled eyes due to lack of sleep, but this serum has changed my eye area dramatically in just one short week. I kept the serum in the fridge for that extra added coolness, which feels super nice when applying with the extra cool metal bead applicator. This is one serum I will continue to buy without a doubt.
