How do i conceal a red scar?

I got surgery about a year ago and I have a big red scar from it. Its not a big deal but its really red and I have tried covering it but its not completely healed so it can sometimes get infected any suggestions on how to concel it?

Mederma you can buy it at the store its suppose to be good

eye drop's work to remove reness

They have a T.V. commercial that sells that all natural makeup that is suppose to cover every thing. But you could check with a dermatologist just to be safe. Or you could put askin colored bandaid on it.

aspirin has been known to cure scars and skin impurities. google aspirin facemask even though the results will be for face, you can use it on body parts too. I use it as a weekly facial exfoliator, and it does the skin wonders.

good luck
