Common Skin Problems That Dermatologists Treat

Acne-Related Conditions

Acne is one of the most prevalent skin conditions, affecting both teenagers and adults. It occurs when hair follicles become clogged with oil and dead skin cells, leading to various types of blemishes such as blackheads, whiteheads, papules, pustules or cysts.

Mild acne may respond to over-the-counter products containing benzoyl peroxide or retinoids. However, moderate to severe acne, particularly cystic acne, requires professional treatment. A dermatologist can prescribe oral medications, topical treatments or recommend procedures such as chemical peels to address both active acne and residual scarring.

Eczema and Inflammatory Skin Diseases

Eczema, or atopic dermatitis, is a chronic inflammatory condition that causes dry, red, itchy patches on the skin. It often appears in childhood but can persist into adulthood. Another inflammatory condition is psoriasis, which presents as scaly, red patches that often appear on the elbows, knees, scalp and back. These conditions may be triggered by environmental factors, allergens or stress.

Dermatologists provide tailored treatments, including moisturisers, soap-free cleansers and topical corticosteroids, to relieve itching and reduce inflammation. For more serious cases, dermatologists may recommend phototherapy or oral immunosuppressive medications.

Pigmentation and Sun-Related Conditions

Pigmentation issues, such as melasma or post-inflammatory hyperpigmentation, are common in Singapore due to year-round sun exposure. These conditions manifest as dark patches or uneven skin tone. Sun-related damage, including actinic keratosis or solar lentigines (sunspots), may also occur with prolonged ultraviolet (UV) exposure.

A dermatologist will evaluate pigmented lesions to determine appropriate treatment options, which may include topical lightening agents, chemical peels, laser treatments, or cryotherapy. Early detection and treatment of suspicious pigmented lesions are crucial for identifying potential skin cancers.

Infections

Skin infections can be caused by bacteria, viruses, fungi, or parasites. Common examples include fungal infections like ringworm, viral infections like warts or herpes, and bacterial infections such as impetigo. These conditions often present with redness, itching or pain.

Recurring infections may indicate a weakened immune system or underlying health problems. A dermatologist can identify the root cause and prescribe appropriate treatment to clear the infection and prevent recurrence.

Hair and Scalp Conditions

Hair and scalp issues, such as hair loss (alopecia), dandruff or seborrheic dermatitis, are frequently addressed by dermatologists. Alopecia may result from genetic predisposition, hormonal changes or autoimmune conditions, while scalp conditions like dandruff can cause itching and flaking.

Dermatologists can determine the underlying cause through examination and diagnostic testing, then provide targeted treatments, ranging from medicated shampoos and topical solutions to advanced options like platelet-rich plasma (PRP) therapy for hair loss. A dermatologist’s expertise ensures a comprehensive approach to restoring scalp and hair health.

Nail Disorders

Thickened, brittle or discoloured nails may indicate fungal infections, psoriasis or systemic medical conditions. Any changes in nail appearance should not be dismissed as purely cosmetic concerns, as they may signal underlying health issues requiring medical attention.

A dermatologist can determine the cause of nail changes through a clinical examination and, if needed, laboratory tests. Depending on the diagnosis and severity, they may prescribe topical treatments, oral medications or newer options such as laser therapy.

Serious or Chronic Skin Conditions

Dermatologists play a crucial role in diagnosing and treating serious skin conditions that can significantly impact health and quality of life. These include rosacea, chronic urticaria (hives) and autoimmune conditions, as well as skin cancers including basal cell carcinoma, squamous cell carcinoma and melanoma.

Early detection of skin cancer through regular dermatological examinations helps prevent disease progression. A dermatologist is trained to identify suspicious lesions and perform biopsies when necessary to confirm diagnoses and guide treatment decisions.
