What Is Medical Dermatology?
Medical dermatology focuses on the diagnosis and treatment of skin diseases that affect the health and function of the skin, hair and nails. Treatments and diagnoses are offered for inflammatory conditions, infections, autoimmune disorders and long-term issues like psoriasis or acne. Some conditions are isolated to the skin, while others are connected to internal health or systemic disorders and require a broader approach.
Common Skin Conditions Treated at AboutSkin
Acne
Acne is one of the most frequently diagnosed skin conditions. It often begins with blocked follicles that form whiteheads and blackheads. When bacteria become trapped inside the follicle, it can cause inflammatory acne like papules, pustules, nodules or cysts. We treat acne using topical or oral prescriptions, as well as in-office therapies.
Atopic Dermatitis (Eczema)
Atopic dermatitis is a chronic inflammatory condition that causes dry, irritated, and itchy skin, with flares that vary in intensity. This form of eczema frequently begins in childhood but may also develop later in life, with symptoms showing up on the hands, feet, neck or inside the elbows and knees. Because it’s linked to both genetic and environmental triggers, treatment typically involves reducing inflammation, relieving itch and minimizing exposure to known irritants.
Rosacea and Redness
Rosacea is a chronic inflammatory condition that causes visible redness, flushing and small blood vessels to appear across the central face. Triggers like heat or sun exposure can worsen symptoms, and some patients develop acne-like bumps or thickened skin. Because the condition can progress and lead to permanent changes, early diagnosis and treatment are important and may include topical agents, oral medications or light-based treatments, along with avoiding triggers.
Psoriasis
This chronic autoimmune condition is characterized by an overactive immune response that causes skin cells to multiply too quickly, leading to thick, red patches with scaling. Symptoms of psoriasis often appear in cycles and may include itching, burning and cracking in the scalp, elbows, knees or joints. Although the exact cause is not fully understood, genetics and environmental factors are known contributors. Management may involve topical therapies, systemic medications, or injectable biologics.
Actinic Keratosis
If you have rough, scaly patches on sun-exposed skin, it may be actinic keratosis. This condition is classified as precancerous due to its potential to progress into squamous cell carcinoma. Lesions typically develop gradually as a result of cumulative ultraviolet (UV) damage from natural sunlight or artificial sources. Persistent or recurring patches should be evaluated by a dermatologist to assess risk and determine if cryotherapy or light-based treatments are needed.
Alopecia (Hair Loss)
Hair loss, also called alopecia, may result in gradual thinning, patchy bald spots or widespread shedding, depending on the cause. This skin condition can result from autoimmune disease, genetic predisposition, environmental stressors or physical trauma to the scalp. Diagnosis involves identifying the pattern and underlying cause, and management may include topical or oral medications, steroid injections, PRP therapy or laser-assisted cosmetic options to support regrowth and reduce further loss.
Hyperhidrosis
Sweating is normal and healthy, but when it exceeds what the body needs to regulate temperature, it can signal a condition known as hyperhidrosis. Hyperhidrosis can be treated using topical aluminum chloride and oral medications as well as in-office solutions like Botox or iontophoresis, depending on severity and affected areas. Evaluation by a Board-Certified Dermatologist is important for determining the cause and finding the right treatment strategy.
Lichen Planus
Lichen planus is an inflammatory condition believed to result from an autoimmune response that targets the skin, mucous membranes, scalp or nails. You may notice itchy, purple, flat-topped bumps that sometimes develop white streaks. Diagnosis and treatment depend on the location and severity of symptoms, with management options including topical or oral medications and light-based therapies to reduce inflammation and immune activity.
Melasma
Melasma is a pigmentary disorder that leads to dark, patchy discoloration on areas of the skin frequently exposed to sunlight, especially the face. It is most often associated with hormonal fluctuations, sun exposure and genetic predisposition, and is more common in individuals with medium to darker skin tones. The excess pigmentation results from overstimulation of melanocytes, the cells responsible for melanin production. Although not harmful, melasma can be persistent and difficult to manage without medical treatment.
Molluscum Contagiosum
Molluscum contagiosum is a viral skin infection that causes small, dome-shaped bumps with a central indentation, commonly found on the trunk, limbs or face. It spreads through direct contact, shared items or scratching existing lesions. Although the bumps are usually harmless and may resolve without treatment, many patients choose to address them with cantharidin or cryotherapy to reduce the spread and improve skin appearance.
Skin Cancer
Skin cancer is one of the most frequently diagnosed skin diseases, with basal cell carcinoma, squamous cell carcinoma and melanoma accounting for the vast majority of cases. It develops when DNA damage from ultraviolet radiation triggers abnormal cell growth in the outer layers of the skin. Diagnosis typically requires a biopsy, and treatment options may include surgical excision, topical medications or Mohs micrographic surgery.
Skin Lymphoma
Skin lymphoma, or cutaneous T-cell lymphoma (CTCL), is a rare form of non-Hodgkin lymphoma in which cancerous T-cells collect in the skin instead of the lymph nodes or internal organs. Diagnosis involves a combination of clinical evaluation, biopsies and molecular testing to distinguish it from more common skin diseases. It is managed through topical chemotherapy agents, corticosteroids, light-based treatments or systemic medications, depending on disease stage and progression.
Warts
Warts are common viral skin growths caused by the human papillomavirus (HPV), which stimulates excess cell growth in the outer skin layer. While harmless, they may cause pain, irritation, or spread to other areas if not treated. Treatment options include cryotherapy, immune-stimulating injections, topical agents and advanced methods like microwave-based therapy.
When to See a Dermatologist
Everyone should see a dermatologist once a year for a full skin exam, even if you don’t have an active skin condition. Annual visits help detect early signs of skin cancer and assess any subtle changes that may require attention. You should schedule an appointment sooner if you notice anything new, like a persistent rash or skin infection that doesn’t respond to over-the-counter treatment.
