Many skin care products contain comedogenic ingredients that can cause or exacerbate acne prone skin. If you are acne-prone, you will want to use products/ingredients that are predominantly 0's, 1's and 2's. None of the ingredients are above this rating.
We suggest that you never test more than one new product at a time on your skin as it can take several weeks for a "problem" ingredient to start showing on your skin. Give at least 4 - 6 weeks before adding another product into your daily skin care routine. If you don't do this, you may be liable to blame the wrong product for your problems.
