What is the purpose of pimples?

What is the biological reason for pimples?

Acne is caused when tiny holes in the skin, known as hair follicles, become blocked. Sebaceous glands are tiny glands found near the surface of your skin. The glands are attached to hair follicles, which are small holes in your skin that an individual hair grows out of.

Why pimples occur on face in teenage?

What Causes Acne? Acne is caused by overactive oil glands in the skin and a buildup of oil, dead skin cells, and bacteria, which leads to inflammation (swelling and redness) in the pores. Oil glands get stimulated when hormones become active during puberty. That’s why people are likely to get acne in their teens.

What’s inside a pimple?

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.

Can acne be genetic?

There’s no specific acne gene. However, genetics can play a role in whether you’re prone to acne. In addition to genetics, hormones and lifestyle factors can also affect skin and breakouts. No matter what’s causing your acne, it can be treated.

Why is acne only on face?

Acne typically appears on your face, forehead, chest, upper back and shoulders because these areas of skin have the most oil (sebaceous) glands. Hair follicles are connected to oil glands.
