What is acne? Acne is a chronic disorder of the hair follicles and sebaceous glands located in the middle layer of the skin. In acne, the sebaceous glands are clogged, which leads to pimples and cysts.
Is acne in the dermis?
It is within the hair follicle and sebaceous glands that acne begins.
Where does acne occur in the skin?
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. The follicle wall may bulge and produce a whitehead. Or the plug may be open to the surface and darken, causing a blackhead.
What layer of skin is cystic acne?
Pores in the skin can clog with excess oil and dead skin cells, causing pimples. Bacteria can enter the skin pores and get trapped along with the oil and skin cells. The skin reaction causes swelling deep in the skin’s middle layer (the dermis). This infected, red, swollen lump is an acne cyst.
What area of the integumentary system does acne affect?
Hair Follicle: The sebaceous gland produces oily secretions that can block the follicle, resulting in a pimple. Acne, clinically known as acne vulgaris, is a common human skin disease affecting skin with the densest population of sebaceous follicles such as the face, upper parts of the chest, and back.
What is the middle layer of skin?
The epidermis and the dermis are the top two layers of skin in your body. The epidermis is the top layer, and the dermis is the middle layer.
How many layers make up the epidermis?
The first five layers form the epidermis, which is the outermost, thick layer of the skin. The functions of the five layers of the epidermis are: Stratum corneum: This is the topmost layer of the skin and is made up of keratin.
Why pimples occur on cheeks?
Acne occurs when the pores of your skin become blocked with oil, dead skin, or bacteria. Each pore of your skin is the opening to a follicle. The follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin.
What are the layers of skin?
As the body’s largest organ, skin protects against germs, regulates body temperature and enables touch (tactile) sensations. The skin’s main layers include the epidermis, dermis and hypodermis and is prone to many problems, including skin cancer, acne, wrinkles and rashes.
When does acne occur?
Acne commonly starts during puberty between the ages of 10 and 13 and tends to be worse in people with oily skin. Teenage acne usually lasts for five to 10 years, normally going away during the early 20s. It occurs in both sexes, although teenage boys tend to have the most severe cases.
How do cyst pimples form?
Cystic acne is a type of acne where painful cysts form under your skin. It emerges when dead skin cells, oil, and bacteria get trapped in your pores. That leads to infection under the skin’s surface. The infection weakens the walls between your skin’s cells, creating large fluid sacs that are commonly known as cysts.
What is the hard white stuff in a pimple?
Pus, a thick, white substance made up of bacteria and white blood cells, sometimes fills the pimple. Boils also start in hair follicles.

Which layer of skin are hair follicles located?
The hair follicle is a tube-shaped sheath that surrounds the part of the hair that is under the skin and nourishes the hair. It is located in the epidermis and the dermis.
How does acne affect the functions of the skin?
Normally as the body sheds skin cells, the keratinocytes rise to the surface of the skin. When someone has acne, the hair, sebum, and keratinocytes stick together inside the pore. This prevents the keratinocytes from shedding and keeps the sebum from reaching the surface of the skin.
