Im incredible impressed with this serum. It is very thin in consistentcy so i didnt have high hopes for much hydration. But holy heck I was wrong. Since i have been testing this, i gave my regular hyluronic acid to boot and its not coming back lol. My skin feels so soft and hydrated after using this, it will be staying in my routine. The bottle is large so thankfully this will last me awhile. No irritating scents which is a bonus. I am very greatfull to have been gifted this, as it has become a staple in my routine.
