The hard white thing in a pimple is called a sebaceous filament. It is created by sebaceous glands which secrete sebum, an oily substance that helps protect and lubricate the skin. Sebaceous filaments can appear as small white bumps on the skin and are most commonly found around the nose and chin. They can be larger in people who have oily skin.

What is a pimple with a hard white core?

A pimple with a hard white core is likely a type of acne called a whitehead. Whiteheads are caused when excess oils and dead skin cells clog the pores and create a bump that is filled with white or yellowish pus. Whiteheads can be treated with over-the-counter topical treatments, such as benzoyl peroxide, salicylic acid, or sulfur, as well as prescription medications. It is important to avoid picking at or popping the whitehead, as this can lead to infection and scarring.

Why was there a hard thing in my pimple?

A hard thing in your pimple is likely a cyst or a sebaceous cyst. Cysts are closed pockets of tissue that contain fluid, air, or other substances. They can be caused by infection, clogged oil glands, or trauma to the skin. Sebaceous cysts are caused by clogged oil glands and can be filled with a thick, white, or yellow substance. If the cyst becomes infected, it can become painful and may need to be drained or removed.
