Oil-free skin care products mean products that have been scientifically shown to not cause acne

If you skin is prone to acne-blackheads, red bumps, clogged pores, I recommend products labelled oil-free. Another term to look for is non-comedogenic. Cosmetic companies who use this labelling must submit tests on their products. One of the most common tests is the rabbit ear, which can get blackheads like humans due the the presence of similar glands. Products are tested on the rabbit ear with multiple daily or twice daily applications. If the rabbit ear doesn't form blackheads, human skin would not be predicted to get acne from the product.
