I’ve tried a couple BB creams, and have been allergic to the sunscreen or other ingrediants in some of them. If you have very sensitive skin, or rosacea, read the labels. Some so-called sensitive skin products hurt my skin most and make me break out in big red welts. Neutrogena helioplex, I’m looking at you.
I don’t know if it’s a true BB, but the Jane Iredale Glow Time line works well for me. It gives a little more coverage than most of the BBs, and should be applied with a brush. It’s not cheap, and I’ve only seen it in catalogs or, oddly enough, in my local food co-op. My skin has improved in the time I’ve been using it, and I recommend it.
