Since my skin has been looking a little sad with blemishes lately, I pulled this mask out of the pile of free samples I have lying around. The ingredients seemed quality and effective, with tea-tree oil, AHA, witch hazel, and hyaluronic acid just to name a few; cleansing without being too stripping. Honestly, after having this on my face for about 20 mins, I can't make any claims to whether or not it treated my existing acne, but my face did feel very clean and refreshed without that tight dryness that comes with just using astringents. It was gentle and refreshing, but I could tell it was doing something to treat any blemishes that might have been forming. A shame this company isn't cruelty-free, because this sheet mask is right up my alley!
