At the beginning I was afraid to use this powder as it is totally white powder (similar to flour), and it smells like herbs and medicine. The first time I used it I cannot believe how wonderful it was. I have an acne prone and very oily skin, which make me difficult to control it, every time I apply make up or bb cream it doesn't stay for too long (max 4 hours) and immediately get oily, but once I applied this product, I will never want to leave it as it is so effective in controlling my oily skin, now I can wear make up for almost 24 hours and still intact, because this is also sweat resistant, so I cannot explain how good this product is, if you have oily or sensible skin, I recommend this product to you.
