How to conceal under eye bags over 50?

Excuse me, could you elaborate on the best practices for concealing under-eye bags for individuals over the age of 50? Are there specific products or techniques that are more effective for this age group? Additionally, are there any lifestyle changes or habits that can help reduce the appearance of under-eye bags in the long run? I'm particularly interested in understanding how to achieve a more youthful and refreshed look in this area.
