Easy inversions are great for mental clarity, stimulating the endocrine system, bringing a beautiful glow to the face, and bringing prana to our upper chakras. The fresh blood flow and oxygen is indeed like getting an instant facelift.
Hare pose (not Hair pose! :) ), is an easy inversion almost everyone can do. If you are more flexible, you can try holding on to your ankles the whole time, and bringing your head down closer to your knees.
Namaste and Shanti!
