Having oily-combination skin that acne prone are one of a hell combo (in bad way). Wrong use of product or unclean face from leftover make up will result in bad pimple pop up. So i'm quite picky in using make up remover. Which is why i choose bifesta because it really does it job to remove any trace of makeup and even dirt without drying the skin. Well, sometimes it's hard to remove the super-waterproof mascara, but most of the time this product works perfectly well. 1 bottle can last me up to 2 - 3 months depend on the usage also. Really recommended!
