I'm 37 years old and I have been into skin care since 18. I've tried the cheap stuff and the high end stuff. And I can truly tell you that saranghae is amazing. I can notice just from using it for the first time how much more hydrated my skin feels and much softer also. I have sensitive skin and I haven't broken out at all, and when your face is much more hydrated your make up will go on even better. And you have nothing to lose, you have 30 days to try if you don't like it and you will get a full refund. Their customer service is unlike any other, every time I'm worried that I'm not applying something correctly, they always answer my questions almost immediately. You can just purchase one time and then join the membership if you like it, that's what I did but after this supply runs out I'm going to join the membership since you get better discounts. I'm obsessed with this brand!
