Gotta love My Beauty Diary masks. First of all, these masks are really affordable -- around $12-$15 range compared to the individual face masks that cost around $6 at Sephora and Ulta. The sheet masks from this brand are comfortable to wear. They don't feel firm, which means they fit onto your face comfortably. This specific version contains hyaluronic acid, as a result it: helps wound healing, improves skin structure, and increases hydration. I do find that it calms my skin and gives it extra hydration when I wear it. It won't keep my dry skin moisturized throughout the night though.
