I received your 8 Hour Renewal Sleep Mask, and Dr. Brandt's Sleep Mask, and I MUCH prefer yours over theirs. I have combination skin with an oily T-zone, and the rest of my face is dry. This leaves me beautifully moisturized and hydrated throughout the night. I find the Dr. Brandt version leaves me T-zone over oily, and my dry areas thirsty. Strange.
This sleep mask is something I'll definitely take on flights, and wear on dry days here in Cali. The reason for one star less: it's not affordable. Definitely a one off treat.
