I only used for few times but it's amazing, my face became very soft and smooth. This product looks like jelly and it's very easy to be absorbed by the skin.
I can't see the difference after I used for 3 years, but a lot of people said good things about it.
After appling it for overnight, my face became so soft and smooth, it's very easy to apply the makeup on the morning, the most important is my makeup can last for the whole day.
