IT'S EXPENSIVE BUT WORTH THE MONEY!!!!
I'm the kind of person who is willing to go all out and drop some money for good skincare if I know I will use up every drop and love it. I've tried a lot of snail mucin products (my oily acne-prone skin LOVES it) and this one is different! I've tried the COSRX and the Peach Slices and both don't compare to this. Peach Slices have a similar texture while COSRX has a similar result to the SK-II. However, I will say that the SK-II got rid of all my redness and significantly improved my acne and every time I run out I always notice a difference in my skin whenever I don't have it in my routine. The price tag is a little intimidating but there are more reasonable options on Stylevana and Yesstyle.
