The Etude House is one of those places where once you walk in, you'll never know when you'll walk out. I remember when they first opened in Hong Kong last year, you had to wait in line to get in. Even into the late hours of the evening there is a line to get in on a weekday. I thought i was the only one on vacation and didn't have to work the next day. Their products are affordable, and they sell items from face mask to nail polish to hair products. I go crazy over their nail polish..I love how they have the graduation nail polish sets where you can give your nails an ombre look. They also sell tools for you to make designed for your nails. And when you checkout, they give you samples. Their face mask leaves your skin feeling soft and smooth. There's just so much in this store it's hard to decide that to buy. You also don't want to go too overboard. The place gets really pack and they do have crowd control when it gets super busy. I always make a trip to come here everytime I'm in Hong Kong. I absolutely love this place and i'm really hoping they will open on in SF soon. read more
