Okay we all know the love I have for the MSF medium dark? I have used this on a daily basis ever since I first bought it last year as a foundation..it's amazing!!!, but we all know different seasons equals different foundation formula (while for most woman)...so...
MSF: A luxurious domed face powder with minerals, slowly baked to provide a dimensional yet natural-matte finish. Provides perfect low coverage. Use to set and fix foundation or as a touch-up throughout the day.
Since Fall/Winter is here I switched my foundation to mineralize satinfinish(NC42) Wow!!! your talking so much radiances and glow and not in greasy oily way either and studio tech (NC 43) gives you a soft matte coverage...perfect winter foundation for dry skin.
