I got my panda eye type of bruise since teenage (i am 38 now). And my previously diagnose experience from TCM , they gave me response of general genetically deficiency for my yang chi production (kidney yang and liver yang primarily) which unable to sufficiently produce the good energy circulation(maybe from modern medical perspective, correlation with insulin resistance). Which sound empirical in case they are diagnosed from the sexual health perspective( for me, i am not a heavy porn addiction history,but seems my dopamine tolerance are below average)
BTW, a recent attempt by applying GlyNAC , which having certain good start to building up a good sleeping foundation gives me a subtle improvement of the eye socket color diminishing.
