Hey There! I developed these a couple years ago. Our skin gets thinner as we age and we lose fat that cushions the blood vessels. Every little bump that I have, becomes a bruise. Mine is especially the worst on my arms and hands. It takes them a while to go away too. I like you went to the Dermatologist and she said it was nothing. I have used the bruise cream and I can't really take a huge difference.

I tell you what helps cover it....the blemish sticks by Maybelline that you cover dark circles under your eyes. I put lotion on and then dab a little on the bruises and you can barely see them.

I hope this helps. Blessings & Hugs....
