i did one course elswehere in Australia and they did like a hydrafacial then it was one cream, i felt like wasted my money. This course makes sense. Maggie has so much knowledge with Korean skin ,i mean i just did not know why and how it mattered and why Glass skin would and would not work. I paid $3k for the other course and i used this kit for various treatments. I love it i want to buy all these courses. Thank You.
