I went and spent my speedy money on SK-II products, from the cleanser (got that free)to the essential essence, the eye treatment, the whitening cream and brightner, and now the refining treatment. I'm working on fixing my uneven texture and then going into wrinkle prevention. The specialist said I would see dramatic improvement by the end of the summer. Can any of the ladies put their two cents in on this? Great investment or totally overrated?
