Great serum for hydration! I love Neogen's formulas because of how amazingly hydrating they feel without being too heavy.
I received this serum about 1 month away from the expiration date. StyleKorean said it was still fine to use, so I did, and I don't feel like there's anything wrong with the formula. I would just be a bit cautions when purchasing because these types of products shouldn't still be for sale this close to expiry.
