I decided to do a quick review of this product, I have been using it a few months now, and I like how it soothes my skin. It's Skin is a Korean brand that was formulated by dermatologist at Seoul University, and on the It's Skin english website, the products are described as "natural ingredients from nature with state of the art dermatology technology". I purchased this at yesstyle.com for about $20, the reason I bought it was because it's product description stated that it helped to brighten and even out dull skin, and soothe skin exposed to environmental stress I live in southwestern Colorado, and during the summer my skin becomes irritated due to smoke from wildfires near the area and the heat, I am actually the only person I know over 3 that still gets heat rashes and bumps on my face. Licorice is also used for it's anti inflammatory properties, so I was sold on this product. It is a lightweight serum that absorbs easily into the skin, it did not break me out and hydrates my combination skin nicely. I apply a few drops of this every evening to soothe my skin while I sleep, and it has brightened my skin and evened it out a bit. It also layers nicely under my moisturizer. I have been using this since late May, and I am just now getting ready to re-order so the 30ml/1 ounce size does last a decent amount of time. I would recommend this to anyone looking to brighten and soothe their skin.
