Acne

What Is Acne?

Acne, medically known as acne vulgaris, is a common skin condition affecting the hair follicles and their associated oil glands. It develops when these follicles become clogged with excess oil, dead skin cells, and bacteria, producing the whiteheads, blackheads, pimples, and sometimes deeper cysts that most people recognize as acne.¹

Acne vulgaris accounts for roughly ninety nine percent of all acne cases and is by far the most familiar form of the condition, though several other, less common variants exist, including acne that appears in newborns, acne triggered by certain medications, and severe inflammatory forms that can cause significant scarring if left untreated.²

Although acne is often thought of as a condition limited to adolescence, it can persist into adulthood or even first appear later in life, particularly in women, and it commonly affects the face, neck, chest, and upper back, areas of the body where oil glands tend to be most active.¹

Acne pathophysiology involves excessive sebum production, hyperkeratinization of the hair follicles, bacterial overgrowth, and inflammation working together to produce visible lesions.

Symptoms

Acne lesions fall into two broad categories. Noninflammatory lesions include open comedones, commonly called blackheads, and closed comedones, commonly called whiteheads, both of which result from clogged hair follicles without significant surrounding inflammation.²

Inflammatory lesions include papules, small raised red bumps, along with pustules, which contain visible pus, and in more severe cases, larger, deeper nodules or cysts that can be painful and are more likely to result in lasting scars once they heal.²

The severity and pattern of lesions vary considerably from person to person, ranging from a few occasional blemishes to widespread, persistent breakouts covering large areas of the face or body, with severity generally guiding how aggressively a case needs to be treated.¹

Causes

Acne develops through the interaction of several distinct biological processes occurring within the hair follicle and its associated oil gland. Excess sebum, the oily substance produced by these glands, combines with dead skin cells that are not shed normally, creating a clogged environment within the follicle.¹

Within this clogged follicle, a bacterium naturally present on the skin, Cutibacterium acnes, multiplies more readily than it would in a healthy, open follicle. The immune system’s response to this bacterial overgrowth triggers the inflammation responsible for the redness, swelling, and discomfort associated with more severe acne lesions.¹

Hormonal changes play a central role in triggering these processes, since androgens stimulate oil glands to produce more sebum. This hormonal influence explains why acne so often begins during puberty and why it can flare in connection with the menstrual cycle, pregnancy, or certain hormonal medical conditions later in life.¹

Risk Factors

Adolescence represents the period of highest acne risk for most people, driven by the surge in androgen hormones that accompanies puberty and stimulates increased oil gland activity throughout the body.²

A family history of acne raises individual risk considerably, suggesting a meaningful genetic component to how strongly an individual’s skin responds to the hormonal and bacterial factors that drive the condition.¹

Certain medical conditions associated with hormonal imbalance, including polycystic ovary syndrome and other conditions that raise androgen levels, can contribute to persistent or severe acne. Emerging research has also identified links between acne and metabolic syndrome, suggesting a broader connection between acne severity and overall metabolic health in some patients.³

Complications

Scarring is among the most significant long term complications of acne, particularly with inflammatory lesions such as nodules and cysts, which cause deeper tissue damage during the healing process than superficial blackheads or whiteheads.⁴

Research suggests that both the severity and duration of acne influence scarring risk, which is part of why dermatologists emphasize prompt, effective treatment for more severe cases rather than waiting to see whether breakouts will resolve on their own over time.⁴

Beyond physical scarring, acne can have a meaningful psychological impact, contributing to reduced self esteem, social anxiety, and in some cases symptoms of depression, particularly among adolescents and young adults for whom appearance concerns can feel especially significant.¹

Treatment

Topical retinoids, including adapalene, tretinoin, and tazarotene, form a cornerstone of acne treatment by helping to unclog pores and reduce the abnormal shedding of skin cells that contributes to follicle blockage.⁵

Topical benzoyl peroxide reduces the population of acne causing bacteria on the skin and is frequently combined with other treatments, including topical or oral antibiotics, since using benzoyl peroxide alongside antibiotic therapy helps prevent the bacteria from developing resistance to the antibiotic.⁵

For patients with severe acne or acne that has not responded adequately to standard topical or oral therapy, isotretinoin is considered the most effective available treatment and can produce lasting clearance for many patients. Because isotretinoin carries significant risks, including birth defects if taken during pregnancy, it requires careful medical supervision and strict adherence to safety monitoring throughout treatment.⁶

Prevention

While acne cannot always be entirely prevented, particularly when driven by hormonal changes during puberty, gentle and consistent skin care can help reduce breakout frequency and severity. Washing the face twice daily with a mild cleanser and avoiding harsh scrubbing helps prevent additional irritation that can worsen existing lesions.¹

Avoiding picking or squeezing acne lesions significantly reduces the risk of scarring, since manipulating inflamed lesions increases tissue damage and prolongs the healing process compared with allowing appropriate treatment to work over time.⁴

For people prone to acne, choosing noncomedogenic skin care and cosmetic products, which are formulated to avoid clogging pores, along with starting treatment promptly when breakouts begin, can help limit both the severity of individual flares and the long term risk of scarring.²

Why Visual Communication Matters for Acne

Explaining exactly what happens inside a clogged hair follicle, how bacteria and inflammation combine to create a visible lesion, or how a topical retinoid actually works at the cellular level requires visuals that make an entirely microscopic process understandable to patients who only see the surface result.¹

Pharmaceutical companies, skincare brands, and dermatology practices depend on clear illustration and animation to explain the biology behind acne and the mechanisms of the treatments used to address it.

• Illustrating the follicular anatomy involved in acne, from clogged pores to inflamed lesions
• Animating how excess sebum, dead skin cells, and bacteria combine to form different lesion types
• Explaining the mechanism of action for retinoids, benzoyl peroxide, and isotretinoin
• Visualizing the hormonal pathways that drive acne during puberty and beyond
• Supporting patient education materials on treatment options and scarring prevention
• Creating marketing visuals for skincare and dermatology product lines

Frequently Asked Questions

Does diet cause acne?

Research on diet and acne remains an evolving area, though some studies have linked high glycemic foods and certain dairy products to worsened acne in some individuals. Diet is generally considered one contributing factor among several rather than the primary cause.¹

Can adults develop acne even if they never had it as a teenager?

Yes. Adult onset acne is relatively common, particularly in women, and can be triggered by hormonal fluctuations, certain medications, or underlying medical conditions rather than the puberty related hormone surge typically associated with teenage acne.¹

Is popping pimples ever safe?

Generally, no. Picking or squeezing acne lesions increases the risk of scarring and can push bacteria deeper into the skin, potentially worsening inflammation rather than resolving the lesion more quickly.⁴

When should someone see a dermatologist for acne?

Over the counter treatments are often sufficient for mild acne, but persistent, painful, or scarring prone acne, or acne that does not improve after several weeks of consistent treatment, generally warrants evaluation by a dermatologist.⁵

Is isotretinoin safe?

Isotretinoin is highly effective for severe acne but carries significant risks, including birth defects if taken during pregnancy, which is why it requires strict medical supervision, regular monitoring, and adherence to pregnancy prevention programs throughout treatment.⁶

Can acne scars be treated after breakouts clear?

Yes. Various dermatological procedures can improve the appearance of acne scars once active breakouts have resolved, though preventing scarring in the first place through prompt, effective treatment remains the most reliable approach.⁴
