COSRX Advanced Snail 96 Mucin Power Essence. This essence helps the skin to become smoother while keeping the skin smooth and healthy. 100ml / 3.38 fl. oz. New Condition.

I've used the 35% serum and 65 % serum is still there. pure hygiene product plus this serum costs too much so ypu can use it like your trial one and then decide to take a new one or not.
