A dermatologist can clear them one by one with sterile instruments, gently pressing out each plug and emptying each cyst.
Doing it carefully avoids bruising the skin, pushing material deeper or leaving dark marks behind.
Afterwards the skin is cleaned and may look a little red for a day or two, but it usually feels much lighter and smoother.
Regular showers after sweating, a gentle exfoliating wash and loose clothing help stop new blackheads from forming.
Clean up and move on with smoother skin. The videos below show back blackheads and cysts being cleared by professionals.
