What Are the Different Types of Acne Lesions? Understanding Blackheads, Whiteheads, Pustules, Nodules, and Cysts

Acne is a common skin condition that presents in a variety of forms, known as lesions. Each type of acne lesion has unique characteristics, severity, and treatment needs. Knowing the difference can help you manage acne more effectively and prevent long-term skin damage.

1. Blackheads (Open Comedones)

• Appearance: Small, dark or black dots on the skin

• Cause: Occur when a hair follicle is clogged with oil and dead skin cells; the pore remains open, and the content oxidizes, turning black

• Severity: Mild, non-inflammatory

• Common Areas: Nose, chin, forehead

2. Whiteheads (Closed Comedones)

• Appearance: Small, white or flesh-colored bumps

• Cause: Similar to blackheads but the pore is closed, trapping oil and skin cells beneath the surface

• Severity: Mild, non-inflammatory

• Common Areas: Cheeks, forehead, jawline

3. Papules

• Appearance: Small, red, tender bumps without pus

• Cause: Inflammation due to bacteria or irritation of a clogged pore

• Severity: Moderate, inflammatory

• Common Areas: Face, back, shoulders

4. Pustules

• Appearance: Red bumps with a white or yellow pus-filled center

• Cause: A papule that has filled with pus due to bacterial infection

• Severity: Moderate, inflammatory

• Note: Can be tempting to pop, but doing so may lead to scarring

5. Nodules

• Appearance: Large, painful, hard lumps beneath the skin

• Cause: Deep inflammation in clogged pores

• Severity: Severe, inflammatory

• Treatment: Often requires prescription medications; not treatable with OTC products

6. Cysts (Cystic Acne)

• Appearance: Deep, painful, pus-filled lumps that may scar

• Cause: Severe infection deep within the skin

• Severity: Most severe type of acne lesion

• Treatment: Requires dermatological care; may involve oral medication or cortisone injections
