Could you revise some sentences here?

I'm writing an email to my foreign friend and struggling with grammar..If you give me an helping hand, I would really appreciate it!

It's a fad to make up very natural in Korea. Did I tell you before? I have short memory..Women in Korea nowdays don't seem to put their makeup. They look really pure and clean but they all do makeup.
I think makeup technique is getting developed-there are really good and useful cosmetics in Korea now called BB cream. Have you ever heard about that? It's really a big trend here. It has more than 4 funtions from covering, suncreaming, to wrinkle caring. You don't need a lot of complicated process from make up base, suncream foundation, consiler at all. Only this one cream solve every problem. Whe you put it on your face, your skin tone becomes even and you look bright and natural but doesn't look make up. I think Korean girls don't put their eye make up as much as they did in the past. They want to look natural and pure with that light makeup. And they lie to their boyfriend that they didn't makeup-and every boyfriend believes that because they really look pure!
