I. Use a tiny amount of anbusol, bags go and it tightens the crows feet
Ambusol is for pain with gums and teeth, though is more for swelling as opposed to dark circles. Moisturizing the skin surrounding the eyes and/or a concealer works for circles, but because that area of skin is so tender use the ring finger to gently pat moisturiser/ concealer on to blend in, as opposed to rubbing it in.
I've lived for 32 years with this. I've outlived drs who gave me gloomy prognosis. F'm, and live your life in spite of everything. This cannot define us, and we have to fight. Having each other is all we have sometimes but you can reach out anytime you need to.
