Everything about your box, subscription, shipping, and our satisfaction promise.

Products

Each box combines a warm therapy item (steam eye mask or warm compress, chosen from three styles), a blue-light screen filter or glasses, eyelid cleansing wipes, and — in the Pro plan — a desktop humidifier or screen light bar. All items are external-use products; nothing is taken orally.
