In my experience, skin doesn't look that great when it's irritated, and alcohol tends to bother my skin over time. Earth Science relies on witch hazel, sage, rosemary, horsetail, cucumber, sea kelp and peppermint for gentle--yet effective--toning action. The excess oil is sucked away, but my skin doesn't get irritated in the process. Earth Science Clarifying Astringent contains 9 herbal extracts and is hypo-allergenic. It's not tested on animals and contains no animal ingredients. Neither does it contain any methyl or propyl parabens. Effectiveness With a pH 4 balance, the herbal astringent leaves my oily/combination skin feeling clean, balanced and blemish-free. I have no oil slicks or dry patches to worry about. Plus, the naturally-derived ingredient, hyaluronic acid, provides sufficient moisture without added oils. Scent There are no chemical fragrances added to this toner. It has a slight scent from its combination of natural ingredients, but nothing that stands out. Ease of Application Earth Science toner is easy to apply. I generally use a cotton pad to soak up a little toner and then apply to my skin. It dries quickly, with no residue, and I'm ready to follow up with my moisturizer.
