The product is expansive then what I found in the market, secondly why to sell 3 packs, not all the cosmetics suits you because of your dry skin or oily skin, etc. If you want to try this product so buy one pack and try it if it works then buy more. I did a mistake to buy three packs and expansive too. And my skin is very oily and I have constant pimples growing on my face, this product did not help my problem.
