I couldn't find many reviews on the serum when I purchased this product in Taiwan last summer, but it doesn't hurt to try it because nothing disappoints me from this brand. I was a bit nervous to try it in the morning after my AM skincare routine, so I picked a day that I was off from work to experiment with it. I didn't experience any tinkling or breakouts. I actually liked this product. My skin absorbed it quite fast, and it didn't feel sticky on a humid 90F weather. I know there was some hyaluronic acid in this product, so my face felt quite moisturized.
