Skin infections occur when microorganisms enter and multiply within the skin or its deeper layers. They can affect people of all ages and may present with redness, swelling, pain, scaling, discharge, or changes to the skin surface. While some infections settle with early and appropriate treatment, others may worsen, spread, or recur if not properly assessed—particularly when symptoms become increasingly painful, progressive, or slow to improve.
At Auria Dermatology Clinic, we assess and manage different types of skin infections, including bacterial, fungal, and atypical skin infections. Accurate diagnosis is important, as treatment varies depending on the organism involved and the extent of skin involvement.
Impetigo, Folliculitis, Erysipelas and Cellulitis
Bacterial skin infections are commonly caused by organisms such as Staphylococcus or Streptococcus. They range from superficial infections involving the outer skin layers to deeper infections affecting the dermis and subcutaneous tissue.
Bacterial infections may present as red, tender skin, pus-filled spots, crusting, warmth, or swelling. Some conditions, such as cellulitis, can spread quickly and may be accompanied by fever or general unwellness. Pain, worsening redness, or rapid progression often prompts medical review.
These infections may develop when bacteria enter through breaks in the skin, such as cuts, insect bites, eczema, or shaving-related trauma. Risk is increased in individuals with chronic skin conditions, diabetes, reduced immunity, or frequent skin injury.
Management depends on the type and severity of infection and may include:
Early assessment helps reduce the risk of spread or complications.
Tinea, Cutaneous Candidiasis, Pityriasis Versicolor
Fungal skin infections are caused by dermatophytes or yeast and commonly affect warm, moist areas of the body. These infections are generally not serious but may persist or recur without appropriate treatment.
Symptoms may include itchy, scaly, or ring-shaped rashes, skin discolouration, cracking between the toes, or involvement of the nails. In some cases, cosmetic concerns arise due to visible skin changes or pigment variation.
Fungal infections are more likely in humid environments and may be associated with sweating, occlusive clothing, communal facilities, or close skin contact. Underlying medical conditions, such as diabetes or immune suppression, can increase susceptibility.
Management is guided by the location and extent of infection and may include:
Treatment duration varies depending on the type of fungal infection.
Viral & Other Uncommon and Mycobacterial Infections
Skin conditions as a result of viruses are also common and these include viral warts, molluscum contagiosum, herpes zoster (Shingles) and varicella infections. Other atypical skin infections include those caused by non-tuberculous mycobacteria, or other less common atypical organisms. These infections typically present differently from typical bacterial or fungal infections and can sometimes be mistaken for inflammatory skin conditions.
Presentation varies and may include vesicles, pustules, papules, persistent nodules, ulcers, warty growths, or slowly enlarging skin lesions. Symptoms may be mild initially, leading to delays in diagnosis. Lack of response to standard treatments is a common concern.
Risk factors for atypical infection include environmental exposure, minor skin trauma, cosmetic or medical procedures, and reduced immune function. Travel history or occupational exposure may also be relevant.
Management depends on the suspected and/or identified organism and may involve:
Diagnosis is based on medical history and examination of the skin. The assessment may include:
Identifying the causative organism helps guide appropriate treatment.
You may consider seeing a dermatologist if you experience:
A consultation with Dr Laura Hui allows for accurate diagnosis and discussion of suitable management options.
Some skin infections can be contagious, while others are not. This depends on the type of organism involved and how the infection spreads. Certain viral infections, such as molluscum contagiosum, herpes zoster and varicella may be transmitted through direct skin contact, and/or shared personal items.
A dermatologist can advise on what precautions are required to minimise the spread to loved ones, especially special vulnerable groups, such as young children, pregnant ladies and those immunocompromised.
Not all skin infections require antibiotics. Treatment depends on the cause, severity, and location of the infection. Mild or localised infections may respond well to topical treatments or supportive skin care alone. Antibiotics are usually reserved for bacterial infections that are more extensive, deeper, or associated with worsening symptoms.
Using antibiotics only when appropriate helps reduce unnecessary side effects and antibiotic resistance. A proper assessment helps determine the most suitable treatment approach.
Skin infections can recur, particularly if underlying risk factors are not addressed. Factors such as repeated skin trauma, chronic skin conditions, excessive moisture, macerated skin or toe webs, or underlying medical issues such as diabetes, may increase the likelihood of recurrence.
Identifying the type of infection and addressing contributing factors, such as skin care habits or environmental exposure, can help reduce the risk of repeated episodes.
Care at our clinic is consultation-based and focused on accurate diagnosis. Management plans are tailored to the type of infection, symptom severity, and individual health factors.
