Overview
An infected pimple is a common skin condition where a clogged pore or hair follicle becomes inflamed and infected by bacteria, leading to redness, swelling, pain, and sometimes pus formation. Pimples are a hallmark of acne vulgaris but can become secondarily infected if bacteria such as Staphylococcus aureus invade the lesion. In Korea, dermatologists employ a combination of topical and systemic treatments to effectively manage infected pimples, reducing discomfort and preventing scarring.
What is an Infected Pimple?
A pimple develops when pores become blocked with excess oil, dead skin cells, and bacteria, causing inflammation. When this inflammation worsens due to bacterial infection, the lesion can become an infected pimple, characterized by increased pain, swelling, and pus accumulation. This can range from mild papules to painful nodules or cysts.
Symptoms
- Red, swollen bump on the skin
- Pain or tenderness at the site
- Presence of pus or yellowish discharge
- Warmth over the affected area
- Possible formation of a whitehead or pustule
- Surrounding skin may be red and inflamed
Causes
- Overproduction of sebum (skin oil)
- Accumulation of dead skin cells blocking hair follicles
- Colonization by Cutibacterium acnes (formerly Propionibacterium acnes) and other bacteria
- Secondary infection by Staphylococcus aureus or other skin flora due to scratching or manipulation
- Hormonal changes, stress, or certain medications
Risk Factors
- Teenagers and young adults with acne-prone skin
- Poor facial hygiene or excessive touching of the face
- Use of comedogenic cosmetics or skin products
- Underlying skin conditions such as eczema or rosacea
- Immunocompromised individuals
Complications
- Spread of infection causing cellulitis
- Formation of abscesses requiring drainage
- Scarring and pigmentation changes after healing
- Recurrence of infected pimples if underlying acne is uncontrolled
Prevention
- Maintain good skin hygiene with gentle cleansing
- Avoid picking, squeezing, or scratching pimples
- Use non-comedogenic skin products
- Manage underlying acne with appropriate medical treatment
- Seek early treatment for inflamed or infected lesions
