Honestly didn't really notice much of a difference. I definitely didn't get that glass skin look that this serum is named after. Ingredient list is very basic, contains mostly hyaluronic acid + 2% niacinamide and a very very very low amount of peptide. It contains Peach extract (reportedly high in vitamin C) but I did not see any brightening effect at all. It just felt like any other hyaluronic acid serum, which is disappointing considering the price point of the serum. I get waaay better results with Neogen's Micro Ferment Essence which is actually cheaper than this and you get 150mL of product
