Skin Infections

---

The skin serves as the body’s first line of defence against the external environment, acting as a protective barrier against microorganisms and external irritants. However, because the skin is constantly exposed, it can sometimes become vulnerable to infections caused by bacteria, viruses, fungi or parasites. At Clayton Dermatology, our dermatologists diagnose and manage a wide range of skin infections in patients of all ages.

Skin infections typically occur when microorganisms enter the skin through small cuts, breaks or areas where the skin barrier is weakened. Depending on the cause, infections may present with redness, swelling, itching, pain or visible changes such as bumps, rashes or lesions.

Skin infections can be classified according to the type of organism involved:

Bacterial infections – These often present with redness, tenderness, swelling and warmth in the affected area. In some cases, the infection may spread if not treated promptly.

Viral infections – Common examples include warts and molluscum contagiosum, which may appear as small raised bumps or growths on the skin.

Fungal infections – These frequently affect warm and moist areas of the body and may cause itchy, scaly or circular patches.

Parasitic infections – Conditions such as scabies can lead to intense itching and widespread skin irritation.

Because different skin infections can appear similar, an accurate diagnosis from a dermatologist is important to ensure appropriate treatment.

Treatment depends on the type of infection, its severity and the areas of the body involved. Some infections respond well to topical treatments applied directly to the skin, while others may require oral medications.

Certain viral conditions, such as warts or molluscum contagiosum, may require specialised dermatological treatments rather than simple at-home management.

At Clayton Dermatology, each patient is individually assessed, and a tailored treatment plan is developed based on the specific diagnosis and clinical presentation.

Medical advice should be sought if you notice symptoms such as a rapidly spreading rash, persistent or worsening redness, painful swelling or skin lesions that do not resolve over time. Early assessment and treatment can help prevent complications and reduce the likelihood of the infection spreading.

If you are concerned about a possible skin infection, a consultation with a dermatologist can help identify the cause and guide effective treatment options.
