Well, first of all the customer service is really very good because anytime that I have to call them I have satisfaction with whatever is going on and usually I don't have to call him them for anything. I don't return anything because I love the products - they never come damaged. but best of all is my skin. I started using this product many years ago after having a lot of experience with many many different brands. I instantly saw a difference in my skin. I am 80 years young at this point, and I certainly don't look it. my skin is soft and supple and blemish free and it's an easy program to implement. Go for the VIP package with five items. Excellent! Try the facemasks. They are all good and guess what? The price is right. Get into the Saranghae skin care habit.☺️
