Can you suggest anything for malar bags/festoons? I understand they are difficult to treat but I was wondering if an at-home device would be of benefit? NuFACE maybe?

Hmm, anything that helps improve the lymphatic drainage in your face may help the appearance of the malar bags when they get puffy, so NuFACE or a quartz/ jade roller might be of some help, or just manual lymphatic drainage – but none of these things will fundamentally change the malar bags themselves. For that you’ll need to explore tweakment options or if necessary, surgery.
