The sleep mask is hydrating and nurishing and smells heavenly (got he berry one). I like to apply it a tiny tiny amount on the lips in the evening and in the morning the lips feel healty and soft. In the morning I put a tiny amont on the lips like lipgloss. The mask is a bit sticky but not too critical and it came with comfortable packaging and with the lip-tool to get the mask on the lips without smearing your fingers. Overall I just love it and keep using aslong it lasts (and there is a lot).
