Hello, I'm a skincare expert with a background in dermatology. I'm here to help you understand various skin conditions and how to treat them effectively.

The white stuff that comes out of a blackhead is known as sebum. Sebum is a natural oil produced by the sebaceous glands in your skin. These glands are most abundant on the face and scalp. The primary function of sebum is to moisturize and protect the skin, but when it's overproduced, it can mix with dead skin cells and other impurities. This mixture can clog the hair follicles, leading to the formation of blackheads.

Blackheads are a type of acne that appears as small, dark spots on the skin. They get their name from the dark appearance caused by the clogged hair follicle being exposed to air, which oxidizes the mixture inside, turning it dark. When you squeeze or extract a blackhead, the white substance that is released is the sebum that has been trapped inside the follicle.

It's important to note that while squeezing a blackhead may provide temporary relief, it's not a recommended practice as it can lead to scarring and further inflammation. Instead, using proper skincare techniques and products can help manage and prevent blackheads.
