I wouldn't be surprised about anything I hear about Bismuth OxyCloride! I have another idea, though. Are you certain it was bruises? The reason I ask is because there are lots of reasons that the wrong mineral makeup could make you LOOK like you have bruises!
I make wonderful mineral makeup with NO bismuth. I use silk, Aloe, and wonderful ingredients that are terrific for your skin! I am working on my website, MoreMinerals.com. Please call me at 503 747 5543 or write AnnnieHall@aol.com! I love to help people with skin isssues. I can send you some free samples, too!
