## Description

desertcart.com: The INKEY List Ectoin Hydro-Barrier Serum, Advanced Dual-Action Serum, Boosts Hydration, Builds Stronger Skin Barrier, Lightweight Texture : Beauty & Personal Care

Review: Love this serum! Already have two backups. - This unscented serum feels so lightweight but keeps my skin super hydrated and calm. My skin barrier feels stronger and smoother since I started using it. It absorbs fast, layers well with other products, and never feels sticky. I do two layers after my retinol and my skin is so soft and glowy in the morning. I love it so much I’ve already stocked up with two more bottles! It's such a great value.
Review: Does everything it claims it will in repairing your skin barrier! - Wow, best accidental purchase and most serendipitous delivery EVER. Highly recommend this serum! I bought this by mistake when I was looking at skincare products to help after a peel and had a few tabs open and was frantically researching what would help ASAP. It felt like I had no skin barrier at all, skin was dry, wrinkly, red, flaky- more than ever before in my life and the cream I was advised to use was not working at all. I was panicking and needed something that would absorb and moisturize and repair my face as nothing I had at home or would normally use was sinking into my skin or it was irritating my face even more or had fragrances that dermatologists cautioned against using after a peel. I felt like I was wearing a Halloween mask because I looked so awful. Hence the accidental purchase- mass panic ordered a bunch of lotions, serums, balms like Cicaplast, Eucerin, good molecules, stuff with hyaluronic acids and or occlusive properties or things claiming to heal/repair/protect your skin. Was set to return this when I opened the package and read the label- I had been looking at some other Inkey product that I thought I’d clicked BUY NOW on, what was this “ectoin” stuff?! Looked it up and all the ingredients sounded like what I needed and didn’t know I needed. Had already tried a few of the products that arrived before this one and hyaluronic acids made things worse, creams and balms still wouldn’t sink in, were greasy or heavy or felt like they did nothing. In desperation I tried this and ooooooh yes it works. Sank right in, could see my face getting less wrinkled and more moisturized within ten minutes and felt healthier. By the next day my barrier was feeling human again, within a few days it did everything it promised. It’s very lightweight and doesn’t leave any oily residue, it penetrates and hydrates and makes skin silky smooth again. More than pleasantly surprised, would recommend this every time to someone after a peel or after a sunburn or with a damaged skin barrier!
