My ears are too thin what can I do? (photo)

Hello, my name is Ryan i have stretched my ear i got them upto 40mm but then the tunnels which was wooden dried out my ear and as i taken them out on my left ear the skin on my ear had dried out and it ripped some of the skin on the inside of my ear, is there anything i can do to make them thicker at like 5-6mm thick because i really want to stretch them back to 40mm i have had them out for about a month now and i have used jojobo oil on both to help them but they dont seem to work
