What Is Dermatology?

Dermatology is the medical specialty that focuses on the diagnosis, treatment, and prevention of conditions affecting the skin, hair, nails, and related tissues. Doctors who specialise in this field are known as dermatologists.

The skin is the body's largest organ and plays an important role in protecting against infection, regulating body temperature, and sensing the environment. Dermatologists diagnose and manage a wide range of skin conditions, helping patients maintain healthy skin, hair, and nails while improving their overall quality of life.

Dermatologists specialise in preventing, diagnosing, and treating conditions affecting the skin, hair, and nails. Some people see a dermatologist because of persistent skin problems, while others seek assessment for changing moles, chronic rashes, hair loss, or concerns about skin cancer.

Acne

Acne is one of the most common skin conditions, affecting both teenagers and adults. It occurs when hair follicles become blocked by oil and dead skin cells, leading to pimples, blackheads, whiteheads, and sometimes permanent scarring if left untreated.

Eczema (Atopic Dermatitis)

Eczema is a chronic inflammatory skin condition that causes dry, itchy, and inflamed skin. Flare-ups may be triggered by allergens, irritants, stress, or environmental factors, and treatment aims to control symptoms and reduce recurrences.

Psoriasis

Psoriasis is an autoimmune skin condition that causes skin cells to multiply rapidly, resulting in thick, scaly patches. Although there is no cure, treatment can help manage symptoms and improve quality of life.

Skin Infections

Skin infections may be caused by bacteria, viruses, fungi, or parasites. Common infections include fungal infections, cellulitis, shingles, and warts. Early diagnosis helps prevent the infection from spreading or worsening.

Skin Allergies and Rashes

Skin allergies and rashes can develop in response to allergens, medications, infections, or irritants. Dermatologists identify the underlying cause and recommend appropriate treatment to relieve symptoms.

Skin Cancer

Skin cancer is one of the most common forms of cancer. Early detection of suspicious moles, non-healing sores, or changing skin lesions is important, as prompt treatment often leads to better outcomes.

Hair Loss

Hair loss may result from genetics, hormonal changes, autoimmune conditions, nutritional deficiencies, or medical illnesses. Dermatologists can determine the underlying cause and recommend appropriate treatment options.

Nail Disorders

Nail conditions such as fungal infections, ingrown toenails, nail psoriasis, and changes in nail colour or shape may indicate underlying skin or medical conditions that require assessment.

When Should You See a Dermatologist?

You should consider seeing a dermatologist if you experience:

Persistent acne
Itchy, red, or inflamed skin
A rash that does not improve
A changing mole or new skin growth
A sore that does not heal
Excessive hair loss
Persistent dandruff or scalp problems
