I'm an avid LOVER and subscriber to Essence magazine! This month's (April 2010) issue has a beauty special on the best foundation for Women of Color. It highlights many of the most concerned foundation topics:
-skin concerns (avoiding breakouts, not looking heavily made up)
-how to pick the best formula for your skin type and your needed coverage
-how to make your foundation last throughout the day
-the proper tools to apply your foundation
-special effect foundations that help with blemishes and anti-aging foundation
The article also lists the foundations and prices that will work best for your budget and skin. I haven't seen a more detailed article about foundation for women of color ever, so this article is definitely worth reading!
If you've liked reading this article in Essence magazine-they have a monthly beauty section covering skin, hair and makeup exclusively for women of color.
