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.
Blackheads, or open comedos, are clogged pores that are filled with dead skin cells and oil, not dirt or grime as myth may suggest. The blackish portion of a blackhead — aka the sesame seed — is due to the oxidation of the dead skin cells and oil when exposed to air.
The white color you see is a plug of oil trapped inside the pore. Comedones are actually a type of non-inflamed acne blemish. Like milia, they are extremely common, especially in people with oily skin. Comedones aren't serious, but sometimes they can progress to larger, inflamed pimples.
Nodules are a type of hard pimple that can be large and painful. They form when an infected skin pore or follicle is located deep below the skin surface. Cysts are found deep below the skin when a pus-filled membrane forms around the infection.
Hard pimples are caused when dead skin cells, oil, and bacteria get under the skin's surface. Certain types of hard pimples should be treated by a doctor to prevent them from getting worse and leaving scars.
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.
"It's best to let a pimple run through its life span," Rice says. Left alone, a blemish will heal itself in 3 to 7 days. Popped improperly, it can linger for weeks or lead to scarring.
The white stuff that comes out of your pores like thin strings when you squeeze your nose is called a sebaceous filament. It's mostly made up of sebum (oil that your skin produces) and dead skin cells. This substance typically collects in pores around your nose and chin.
Milia develop under the skin when bits of dead skin cells, made up of proteins called keratin become trapped and create really hard, little white balls. Milia are essentially harmless and usually don't need treated. Typically they will go away within a few weeks to months.
Milia won't pop and can take a long time to go away. Milia can show up anywhere, but they are most common on the face. They may appear around the eyes and cheeks, nose, and forehead. Milia don't hurt or itch.
Apply a clean, warm washcloth to the pimple for up to 5 minutes. Doing this can help soften the skin and allow the contents to come out more easily. Sterilize a small needle with rubbing alcohol. Poke the center of the whitehead gently with the needle.
If you were to squeeze a sebaceous filament, a white or yellow worm-like structure may ooze out. Or, the filament may not produce anything. Always take caution as trying to extract sebaceous filaments can injure the skin and cause permanent scarring. It can also damage and stretch the pore, making it appear bigger.
Don't: Squeeze them.
You might see a gnarly-looking plug in the mirror, your fingers practically itching to pop and squeeze the blemish—don't. "Squeezing can traumatize the skin, introduce bacteria, and damage the pore, which can spread debris and bacteria deeper into the tissue," King notes.
Though you may be tempted to squeeze or otherwise get rid of a sebaceous filament, it's best to leave them alone. Squeezing or picking at sebaceous filaments risks scarring and spreading any bacteria that may be in or around the pore to other parts of your face, causing a breakout.
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.
If you're bleeding, she says to “gently blot the area with a clean tissue or cotton pad and clean the area with alcohol.” Once the blood has stopped, she advises applying a spot treatment containing benzoyl peroxide or salicylic acid as mentioned above.
When a pore becomes clogged or a pimple forms under your skin, your hair follicles can fill up with pus or sebum (oil). Eventually, the hair follicle can burst, breaking the clog away from your pore and beginning the healing process. This is your body's natural mechanism for dealing with clogged pores and acne.
Blind pimples are most often caused by a cyst or nodule underneath the skin. They differ from whiteheads and blackheads, which develop closer to the skin's surface. Blind pimples can be stubborn. They don't have heads that you can soften or “pop.”
Pus, a thick, white substance made up of bacteria and white blood cells, sometimes fills the pimple. Boils also start in hair follicles. They're caused by bacteria like Staphylococcus aureus, which usually live harmlessly on the surface of your skin.
Blood-filled pimples are a result of picking or popping pimples. They are not serious and will not cause any lasting damage to your skin unless you repeatedly pick at them, which can lead to scarring.
Squeezing a pimple can lead to a nodule (hard, red, painful blemish deep within the skin) or a cyst. A cyst develops when a membrane forms around the infection in the dermis, creating a soft, fluid-filled lump that can become large and painfully inflamed.
Calcinosis cutis is the accumulation of calcium salt crystals in your skin. The calcium deposits are hard bumps that don't dissolve. The shape and size of the lesions vary.
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.
Blackheads are caused by dirt and oil that clog your pores and turn black when exposed to air. Help prevent and get rid of nose blackheads by incorporating a combination of cleansers with Salicylic Acid, pore strips, and gentle exfoliation into your skincare routine.
