The integumentary system is the body’s outer layer, made up of the skin, hair, nails, and glands (such as sweat and sebaceous glands). It serves as a protective barrier against external threats like bacteria, UV radiation, and physical damage. It also helps regulate body temperature, provides sensory information, and plays a role in vitamin D production.

Key functions of the integumentary system include:

Protection: Shields the body from harmful UV rays and pathogens.

Temperature Regulation: Sweat glands help cool the body, and the hypodermis insulates against heat loss.

Sensation: Nerve endings in the skin help detect pain, pressure, and temperature.

Acne is a common skin condition that occurs when hair follicles become clogged with oil, dead skin cells, and sometimes bacteria. It usually causes pimples, blackheads, and cysts, most often on the face, chest, and back.

Acne is caused by a combination of factors that affect the skin. The main causes include:

# data[].attributes.body
1. Excess Oil Production: Overactive sebaceous (oil) glands produce too much oil, which can clog pores.

2. Clogged Pores: Dead skin cells mix with oil and block hair follicles, leading to acne formation.

3. Bacterial Growth: The bacteria Propionibacterium acnes (P. acnes) thrive in clogged pores, causing inflammation and infection.

4. Hormonal Changes: Hormonal fluctuations during puberty, menstruation, or pregnancy increase oil production and can trigger acne.

5. Genetics: Acne can run in families. If your parents had acne, you may be more likely to develop it.

Acne comes in different forms. Here's a quick look at the most common types:

Whiteheads: Small, white bumps caused by clogged pores with oil and dead skin. They’re closed and not inflamed.

Blackheads: Open pores clogged with oil and dead skin, turning dark from oxidation.

Papules: Small, red, raised bumps from inflamed pores. These are tender and don't have pus.

Nodules: Large, painful lumps under the skin from deep, inflamed pores. They don’t have pus.

Pustules: Red pimples with a white or yellow center filled with pus. They are inflamed and painful.

 How Acne Affects the Integumentary System.

# data[].attributes.body
Acne affects the epidermis (outer layer of skin), where pores become clogged with oil, dead skin cells, and bacteria. This can lead to inflammation and irritation, resulting in pimples, pustules, and cysts.

Epidermis: Surface layer where acne forms.

Dermis: Deeper layer that can become affected, leading to scarring in severe cases.

Topical treatments: Creams with ingredients like benzoyl peroxide, salicylic acid, or retinoids.

Oral medications: Antibiotics or hormonal treatments in severe cases.

Lifestyle changes: Healthy diet, gentle skincare, and managing stress.

Professional treatments: Chemical peels, laser therapy, or acne extraction by a dermatologist.

Cleanse your skin gently twice a day.

Avoid touching your face to prevent transferring bacteria and oil.

Use non-comedogenic products that don’t clog pores.

Stay hydrated and maintain a balanced diet.

Manage stress since it can trigger hormonal changes that lead to acne.
