Yep, I would also recommend putting on cucumber mask instead of potato one. A cucumber mask I used almost removed disgusting bags under my eyes (side effect of working overtime - don't ask).
Of course, you don't need to apply it every day. From my experience, 2-3 times per week is enough. If you are still unsure what to do, try both of them for a week and decide which one is more suitable for your skin type.
