i LOVE LOVE LOVE my msf!!!!!!!!!! I wear medium-dark and it makes my foundation finish look so polished and natural. just my opinion, but i think it's a great product to blend at the jawline/neck so your face doesn't look a different color bc it's so light. i personally hate putting heavy powders on my neck. it makes me feel really gross. WARNING!! those with dry skin, uneven skin tone, and large pores....wearing MSF alone may increase these flaws. i'm telling you from experience. it's actually not meant to be worn alone...it's a skin finish for your face to go over foundation (never over powder!!!). also make sure that if you wear concealer, don't put MSF over it. it's not a translucent powder (which is what you are supposed to set concealer with). just imagine...your concealer is one shade or more lighter than the rest of your face, and then you add msf or anything with a darker color under your eyes...eeeeeeeeeeekkkk! anyhow, i really do love this product, and i use a paint brush from michael's to set it. it's loew cornell maxine's mop 1". i think it's like $8 and it's also great for highlighting and translucent powders. there is a video on youtube comparing mac and lc brushes by enkoremakeup. great if you want the same as mac but don't want to pay a ton.
