Soothe tired eyes, calm a racing mind, and reset in 20 minutes—Lula’s self-warming eye masks are your easiest moment of self-care. Eucalyptus is a limited edition scent for winter. Eucalyptus Scent: The scents are purposefully subtle so as not to overwhelm your senses while you relax. Eucalyptus is a fresh, clean scent that can help you unwind and clear your mind. The scents are activated as the mask warms, so when the eye mask has heated, you can pull it down over your nose and take a few deep breaths in!
