Masks can pretty much always be applied with either your fingers or a facial brush. Avoid the sensitive eye area from your brow bone to your cheekbone. Spread an even layer of the mask recipe on your forehead, cheeks, nose, chin, and neck. Yes, you can (and should) apply your face mask down your neck and even on your chest and hands. Those neglected areas are prone to the same issues as your face, so cover your chest with your mask and then smooth any extra on the backs of your hands.
