How do I relieve ear blackheads?

Blackheads. Tretinoin (retin-a, atralin, renova) is the mainstay of treatment for whiteheads and blackheads. Tretinoin is a derivative of vitamin a and works by increasing cell turnover and reducing the "stickiness" of the sloughed cells. It helps expel the plugged material returning the pore to normal. Tretinoin can be irritating, so specific instructions should be followed.
