I buy my mineral makeup from one of two small, woman-owned businesses. I've tried a handful of brands, and these I love because they are a great product for a great price and very kind to my sensitive skin. Neither contain Bismuth.J.Lynne
--The coverage is a little more than the other brand I like. My mom prefers this one. Jess packages everything so prettily, it's like getting a present in the mail. Her product is excellent and her prices are more reasonable than most. I have a coupon code for referrals: RCP95303MAD Minerals
--MAD is a great company to do business with. Great prices, and if you need to ask a question Barbi, the owner, emails you back right away. The coverage is lighter than with J.Lynne, and for that reason, as well as the fact that I have a more precise shade match to my skin in MAD than in JL, this is my foundation of choice. I also like her multi-use colors (you can use any of her colors to create eyeshadow, liner, blush, lipcolor, or even nail polish--it's pretty cool!).
Both companies offer reasonable prices on samples. MAD offers 5 sample sets for $8. JL has $2 individual samples, and of course you'll get a discount with the code.
In my experience, the foundation is enough. You don't really need to layer it with correctors or veils or setting powders or anything like that. I do find that the right kinds of brushes help. Very adequate, if not deeply luxurious, brushes are available at Target. I use the concealer brush with the foundation powder and "paint" it on any spots (under eyes, red splotches, etc.) then use the "bronzer" brush to "buff" the foundation all over my face.
