Your skin will actually thicken over the knee. My doctor would joke about it being "elephant knees". I like to wear the sleeves for the compression and it keeps the joint warm for less injuries. Try to avoid using them in competition though. It gives the opponent something dry to grip rather than a sweaty knee.
