Received a sample with purchase at Ulta. The serum feels nice, but ultimately is not worth the money. There are other products that can do the same for less.

Advanced Night Repair Synchronized Multi-Recovery Complex Serum

Very hydrating serum, leaves my skin super silky and helps with texture over time due to Bifida Ferment Lysate. I will not repurchase though because nowadays there are cheaper Korean alternatives and I do not need such hydration at the moment.
