I'm currently on my second bottle of this serum, and I am certain I will continue to keep purchasing it. I have generally normal skin that sometimes experiences some slight redness after washing my makeup off for the day. I find that this serum works really well to calm that redness in a quick amount of time, but it also works really well with my other hydrating layers (toner and essence) to keep my skin feeling hydrated and soft throughout the day/night. I have noticed some brightening of my skin, meaning I can tell that since beginning to use this my complexion looks more lively and pretty. Highly recommended!
