You can try rubbing some bag balm or vitamin E (poke a capsule and squeeze it out) gently into the ear and see if that helps. Sometimes it's just a dry ear and needs to work the flakes off.
Also just wanted to mention with chins with light colored ears, they can get "bruises." My pink white boy kept getting purplish/reddish marks on his ears, and they would go away after awhile. Though I suspect this isn't the case with your little one, since the red marks are so small.
But do watch out for the redness getting bigger, and flakier. Also if there is scratching. May be a sign of fungus.
