Acne develops when hair follicles become clogged with oil and dead skin cells, which can lead to inflammation and pimples.

According to the American Academy of Dermatology, acne is the most common skin condition in the United States, affecting up to 50 million Americans annually.

At Bay Biosciences, we provide high-quality, clinical-grade human biospecimens that can support research into skin conditions, inflammatory pathways, biomarkers, and disease mechanisms.

Understanding Acne

Acne is a common inflammatory skin condition that primarily affects areas with a high concentration of sebaceous glands, including the face, chest, upper back, shoulders, and neck.

The skin contains hair follicles connected to sebaceous glands. These glands produce sebum, an oily substance that helps lubricate the skin.

When excess sebum combines with dead skin cells, it can block a follicle and create a comedone.

Inflammation and changes in the skin microbiome can then contribute to the development of acne lesions.

Although acne is generally not dangerous, severe or persistent acne can cause permanent scarring and may significantly affect quality of life.

Types of Acne

Understanding the Types of Acne helps researchers and healthcare professionals distinguish between different types of lesions and disease severity.

Blackheads

Blackheads are open comedones that develop when a blocked pore remains open at the skin surface. The dark appearance results from the contents of the pore reacting with air rather than from dirt. 

Whiteheads

Whiteheads are closed comedones. They form when oil and dead skin cells block a follicle while the opening remains closed.

Papules

Papules are small, raised, inflamed bumps. They typically develop when inflammation affects the walls of a blocked follicle.

Pustules

Pustules are inflamed lesions containing pus. They generally have a red base with a white or yellow center.

Nodules

Nodules are larger, firm, and deeply embedded inflammatory lesions. They can be painful and may increase the risk of permanent scarring.

Cysts

Cysts are deep, painful inflammatory lesions that contain pus. Cystic acne is considered a severe form of acne and can result in significant scarring.

Common Causes of Acne

There is no single cause of acne. Instead, several processes contribute to its development.

Firstly, excess sebum production can contribute to clogged pores. Sebaceous glands may become more active in response to hormonal changes, particularly during puberty.

Secondly, abnormal shedding of skin cells can cause dead cells to accumulate within hair follicles. When these cells combine with sebum, they can create plugs that block pores.

Thirdly, inflammation plays an important role in acne development. The immune response to changes within the follicle can contribute to redness, swelling, and painful lesions.

Moreover, hormonal changes are among the most important causes of acne. Androgens, including testosterone, can stimulate sebaceous glands and increase sebum production.

These hormonal fluctuations can also affect acne during menstruation, pregnancy, and other periods of hormonal change.

Furthermore, bacteria also play a role in acne development. Cutibacterium acnes, a bacterium naturally present on the skin, can multiply within clogged follicles and trigger the immune response that leads to inflamed lesions.

Similarly, certain medications may also trigger or worsen acne.

Finally, while research suggests that stress does not directly cause acne, it can worsen existing breakouts.

Acne Risk Factors

Several acne risk factors may increase the likelihood of developing acne or experiencing more persistent symptoms.

Firstly, age is an important factor because hormonal changes during puberty can increase sebaceous gland activity.

Secondly, family history can influence acne risk. People whose parents experienced significant acne may have a greater likelihood of developing the condition.

Moreover, a history of severe acne can also increase the risk of permanent scarring, particularly when inflammatory lesions are repeatedly squeezed or picked.

Diagnosis of Acne

Healthcare providers usually diagnose acne by examining the skin and identifying the type and distribution of lesions.

A dermatologist may assess:

  • The number and type of lesions
  • Whether lesions are superficial or deep
  • The amount of inflammation
  • Areas affected by acne
  • The presence of scarring
  • Possible hormonal or medication-related triggers

Laboratory testing is not normally required for straightforward acne.

However, healthcare providers may consider additional evaluation when acne appears suddenly in adulthood, is unusually severe, or occurs alongside other signs of hormonal abnormalities.

Acne Treatment

Acne Causes and Treatment are closely related because treatment aims to address one or more of the processes involved in acne development.

For mild acne, topical products may contain ingredients such as benzoyl peroxide, salicylic acid, azelaic acid, or topical retinoids. These treatments can help reduce clogged pores, inflammation, or acne-associated bacteria.

For moderate or severe acne, dermatologists may prescribe stronger topical treatments or oral medications.

Treatment may include oral antibiotics, hormonal therapy for appropriate patients, or isotretinoin for severe acne that has not responded adequately to other treatments.

Treatment choice depends on acne severity, lesion type, the patient’s age, medical history, and other individual factors.

Acne Prevention

Although acne cannot always be completely prevented, several measures can help reduce breakouts and minimize irritation.

Important approaches to acne prevention include:

  • Gently wash the skin with a mild cleanser.
  • Avoid aggressive scrubbing.
  • Choose non-comedogenic skin-care and cosmetic products.
  • Avoid repeatedly touching, squeezing, or picking acne lesions.
  • Remove makeup before sleeping.
  • Wash after activities that cause excessive sweating.
  • Follow a consistent skin-care routine.
  • Use acne treatments as directed by a healthcare professional.

The Importance of Acne Samples in Research

Human biospecimens can help researchers investigate the biological mechanisms involved in acne and other inflammatory skin disorders.

Researchers can use well-characterized human samples to investigate:

  • Inflammatory pathways
  • Skin microbiome interactions
  • Sebum-related biological processes
  • Hormonal influences
  • Biomarker discovery
  • Genetic and molecular factors
  • Immune responses
  • Disease severity
  • Treatment response
  • Development of new therapeutic approaches

Similarly, human serum samples and plasma samples can support research into circulating proteins, hormones, inflammatory mediators, and other biomarkers.

Moreover, researchers may also use human tissue samples when studying cellular and molecular changes within affected tissues.

Finally, well-characterized human biospecimens can therefore support translational research investigating how biological and environmental factors contribute to acne.
