The skin on the inside that lines the balloon is producing skin cells. Instead of those skin cells falling off into the atmosphere, the cells become trapped in the balloon.
The balloon grows as it becomes filled with skin cells. The balloon may even rupture, which causes the cyst to become painful. Ideally, a cyst should be removed before it ruptures.
When a cyst ruptures, the skin cells in the balloon disperse and break up in the area under the skin. The cyst can repeatedly rupture and fill up. This cycle is not only painful, but it also creates scarring in the area. Chronically ruptured cysts are complicated and difficult to treat because the area turns into a mix of scar tissue and a number of small cysts that have broken off and formed.
Think of cysts like a balloon of skin cells. It has a little opening at the top that leads to the outside. Underneath the skin, the balloon is filled with dead skin cells… and continues to fill with these cells. See a GP if you think the cyst is infected. You may need a course of antibiotics. Although some GP surgeries have minor surgery facilities, most do not remove cysts.
You may be referred to a specialist, or you could pay for private treatment. During a cyst removal, a local anaesthetic is used to numb the skin. A tiny cut is made in the skin and the cyst is squeezed out. This procedure will leave a scar. The cyst may also grow back, particularly if it was removed from the scalp or scrotum.

What a cyst looks like A skin cyst is a round, dome-shaped lump. Foul-smelling pus coming out of the cyst is another sign of infection. Bathe the cyst gently with clean, warm water, and then dab it dry. Skin cysts develop when cells multiply and move inward, rather than moving out to the surface of the skin and shedding away as skin cells normally do.
The epidermis is the top layer of the skin, and the outermost layer of the epidermis is where skin cells eventually shed away. Underneath the epidermis is the dermis layer. The cause of a cyst is not always obvious. In some cases, there is a genetic reason for it. Pilar cysts , which develop around hair follicles, might also have a genetic basis.
Most cysts do not develop complications. The most likely complication is a skin infection, which can occur if bacteria enter the cyst. Cysts are not fixed to anything deeper or below the skin, and the cyst and the area of skin around it is moveable. Very rarely, however, a cyst can extend deeper into the body and connect to underlying tissue. A person should see a doctor if they have a fixed lump that does not move. Skin cysts, or sebaceous cysts, are fluid-filled sacs that develop on the skin.
They are usually harmless, but a doctor may recommend draining or removing a cyst if it becomes uncomfortable. People should see their doctor if they notice any new lump on the skin or are concerned about an existing lump.
A skin infection occurs when parasites, fungi, or germs such as bacteria break into the skin. Here, learn more about skin infections and what they….
