Stung my face a little bit when I first tried it, could be from many factors since I was trying it with other new serums. 

Kept face hydrated throughout the day, does well when layered under water based serums, helped during bad retinol peeling days. 

Did not work well on my face since it has danmaged skin barrier, stung and unpleasant sensation.

Face: brightened skin, gentle exfoliating 
Arm pits: 100% took away my BO, that’s a 10/10 in my book. Did not lighten them but I didn’t smell. 

Harsh white cast, pilled up with some skincare products like Niacinamide but not with Cosrx snail serum. 

Gave a nice glow to the skin. I enjoyed the product and would recommend it for those who wears sunscreen alone.
