Bare Escentuals Rare Minerals Blemish Therapy is one of the makeup items I always keep on hand. Whenever I see the start of a blemish, I apply this product on my blemish. It helps prevent the blemish from becoming worse, and it actually helps the blemish clear up more quickly. This also really helps eliminate the redness on any blemishes. Once you put this product on your skin, you can put makeup on right over this product. This comes in a small, round container. I typically use a small bare escentuals brush to apply it, but you can also use your finger. You just tap a little bit of the powder product onto your blemish. You don't really have to blend it in if you plan to put makeup on over the powder. This does not have a very good scent, but that's understandable since it is actually sulfur. It is not so bad that it keeps me from using the blemish therapy. Another reason I like Bare Escentuals Rare Minerals is because the products are natural. This is very important to me to use natural skincare, so I will continue to use this product even though it is a little expensive. I think it is well worth the cost. Effectiveness This helps shorten the time of breakouts, and it takes away the red-ness from blemishes. Ease of Application This is very easy to apply. It is a powder consistency. I just put a small amount onto a brush and tap it over the blemish. You can blend it in if you put too much on your face, but you don't have to worry about blending it if you plan to put makeup on over top the product. Convenience I normally carry this container along with me in my purse. It is very convenient, and the container doesn't spill out the powder. Side Effects I have sensitive skin, and I have no negative side effects from this product.
