Those with sensitive skin know it's easy to get irritated, which is why fit and material are both important. Lightweight and breathable cottons and silks will be your best friend, but make sure to pay attention to the fit as well.
Aguliar says, "A mask for sensitive skin should fit perfectly to avoid any irritation — it shouldn't be too tight, too heavy, too thick or have any pressure marks especially on the bridge of the nose or cheeks. Pressure marks can leave those areas of the skin red and tender for hours and even days."
Be sure to look for something that has adjustable options, so you can adjust the ear loops or the nose bridge to your size, making sure it won't slip around and rub against your skin.
These Hedley & Bennett The Wake Up & Fight Mask ($22, for three) are no-nonsense masks that feature comfortable ear loops and a fitting nose wire.
