Pimple pus is made from sebum (oil) that gets trapped in your pores, along with a combination of dead skin cells, debris (such as makeup), and bacteria. When you have inflammatory acne lesions (such as pustules, papules, nodules, and cysts), your immune system activates in this area, resulting in noticeable pus.
Vesicles are small fluid-filled sacs or blisters that can appear on your skin. The fluid inside these sacs may be clear, white, yellow, or mixed with blood. Vesicles are fluid-filled lesions less than 5 mm (1/2 cm). If the fluid-filled lesion is greater than 0.5 mm, it's called a bulla.
It's tempting, but popping or squeezing a pimple won't necessarily get rid of the problem. Squeezing can push bacteria and pus deeper into the skin, which might cause more swelling and redness. Squeezing also can lead to scabs and might leave you with permanent pits or scars.
Basically, what happens if you don't pop a whitehead is that it goes away on its own, usually in 3 to 7 days. It may happen that you wake up one morning and notice the pimple is gone. Or you may notice the pimple draining.
Persistent Pimple Rx
One reason a pimple keeps popping up in the same place is that the pore it developed in is damaged -- usually the result of too much picking. Prodding at a pimple can loosen the cell lining of the pore and cause the clogged oil to slip deeper into the skin, creating an inflammatory reaction.
What is the clear liquid/fluid that comes out of a pimple? "Clear fluid is just oedema – fluid that accumulates in the area due to redness and swelling. It is not pus, and it is not an infection."
A sebum plug can look like a tiny bump under the surface of the skin or it may stick out through the skin like a grain of sand. When a sebum plug forms, bacteria that normally lives harmlessly on the surface of your skin can start to grow within the follicle. Inflammation follows, causing a breakout.
What Causes a Painful Pimple? Pimples hurt because the body is trying to get rid of the stuff that doesn't belong there. The redness, swelling, and inflammation cause the pain. The body knows that the dead skin, oil, and bacteria are supposed to be in the hair follicle (which is outside the skin).
In fact, blood-filled pimples happen as a result of the picking or popping of a regular pimple. The forced trauma to that area of the skin not only pushes out puss — the white or yellow liquid bacteria — but also blood where the skin or pimple is infected or irritated.
Clean up. After you've popped the pimple, wash your face and hands a second time with antibacterial soap, and then apply a small amount of alcohol to the remains of the blemish—this will help keep bacteria from repopulating it.
Hard pimples can be painful and long-lasting. They are some of the most difficult kinds of pimple to get rid of. Most types of pimples form when dead skin cells, oils, or bacteria block a pore. Hard pimples, such as nodules or cysts, are often deeper and more inflamed.
Cause: Acne lesions are filled with dead white blood cells that feed the bacterial infestation. Because most of these bacteria are anaerobic, they produce their own sulfur compounds as they grow. These sulfur-containing compounds can cause a pungent smell of garlic or onions when you pop the acne.
Popping pimples releases dopamine
After feeling and hearing that “pop”, some people get an immediate sensation of pleasure and relief. That's because dopamine — the happy-hormone — is released when you feel a sense of accomplishment.
Use an antibacterial wash to clean the area, such as benzoyl peroxide. Try one with 2.5%-5% Benzoyl Peroxide to start, as you may find it can be very drying. Apply a topical salicylic acid to the spot. If you find the over-the-counter creams to be too harsh and drying, try a toner with salicylic acid.
"In the event that you pick a pimple, and an infection develops, the worst-case scenario is that the infection spreads from the skin through this sinus [and] has the potential to infect the brain and even spread through the bloodstream to the entire body," said Dr. Zeichner.
The section of your face from the bridge of your nose to the corners of your mouth is sometimes known as the “danger triangle of the face,” or even the “triangle of death.” And it's one place where you should never pop a pimple, as it can lead to an infection in your brain.
Cysts: These are pimples filled with a thick, yellow or white fluid composed of dead white blood cells, small pieces of tissue and bacteria (pus). Cysts can cause scars.
Pimple pus is made from sebum (oil) that gets trapped in your pores, along with a combination of dead skin cells, debris (such as makeup), and bacteria. When you have inflammatory acne lesions (such as pustules, papules, nodules, and cysts), your immune system activates in this area, resulting in noticeable pus.
You can cause a blood-filled pimple by damaging blood vessels around an existing pimple. This often happens when you pop, squeeze, pick or over-exfoliate a pimple. Blood-filled pimples usually heal on their own if you prevent further damage and keep the area clean.
The sebaceous glands are tiny glands in the skin which produce an oily/waxy substance, called sebum, to moisturise the skin and hair. These glands are found in greatest amounts on the face and scalp. Sebum has no smell, but its bacterial breakdown can produce a bad smell.
According to doctors, there is a reason why such pimples called "love" or "crush" pimple. They say boys and girls become much too conscious about their appearance when they discover someone has a crush on them and get stressed about their looks. This may result in pimples be on the nose and around the lips.
Blind pimples are too far below the skin to pop. Trying will only irritate them further, and may cause infection or scarring. Instead of popping, try to bring the pimple to a head so it can exit the skin via other treatment methods. Use a product containing benzoyl peroxide.
However, multiple sebaceous oil glands can be connected to each pore, so the sebum clogged beneath your initial pimple can lead to nearby pores getting clogged. This, in turn, leads to multiple pimples in one spot.
A warm compress can help your pimple open, so it can release pus and start to heal. It's especially effective for pimples under your skin. Soak a washcloth in warm water, and apply it to the pimple for 10 to 15 minutes. You can do this several times a day until the pimple is gone.
“If you pop the pimple, it becomes a micro-wound,” explains Kazin. At this point, it's best to apply a little antibiotic ointment like Neosporin ($6, drugstore.com) at night to help speed up healing. Allowing it to “breathe” during the day without anything on it, if possible, will also help it mend faster.
