Seacoast Dermatology is a premier, physician-led clinical practice providing comprehensive dermatological care to the Portsmouth community. With a legacy spanning over 40 years, this locally owned practice serves patients across multiple locations in New Hampshire, including two dedicated facilities within Portsmouth. The practice offers a full range of medical, surgical, and cosmetic services, specializing in the detection and treatment of skin cancer through advanced techniques such as Mohs surgery.

For residents seeking immediate location details, Seacoast Dermatology operates at 330 Borthwick Avenue, Suite 303, for general dermatology and medical consultations, and maintains a specialized surgery suite at 278 Lafayette Road, Building E. Both locations are accessible via the main clinical phone line at (603) 431-5205.

Understanding the Two Portsmouth Office Locations

To better serve the diverse needs of patients, Seacoast Dermatology has strategically divided its Portsmouth operations into two distinct facilities. Understanding which location to visit is essential for a streamlined healthcare experience.

Medical and Cosmetic Services at Borthwick Avenue

The primary office for general consultations is located at 330 Borthwick Avenue, Portsmouth, NH 03801. Situated in Suite 303, this facility serves as the hub for diagnostic evaluations, routine skin checks, and the management of chronic skin conditions. It is also the primary site for cosmetic consultations and non-surgical aesthetic treatments.

The Borthwick Avenue office is designed to handle high patient volumes while maintaining a focus on individualized care. Patients visiting this location often seek treatment for common concerns such as acne, rosacea, and suspicious moles. The administrative staff and intake specialists are primarily based here, coordinating care across the entire Seacoast network.

Surgical Excellence at the Lafayette Road Facility

The Lafayette Road office, located at 278 Lafayette Road, Building E, Portsmouth, NH 03801, is specifically equipped as a state-of-the-art surgery suite. This location focuses almost exclusively on surgical interventions, most notably Mohs micrographic surgery for skin cancer.

Because surgical procedures require a different clinical environment than routine office visits, the Lafayette Road facility provides a sterile, controlled setting with on-site laboratory capabilities. This allows for the immediate processing of tissue samples, which is a hallmark of the Mohs technique. Patients scheduled for excisions or complex surgical repairs will typically be directed to this location.

Comprehensive Medical Dermatology Services in Portsmouth

The core mission of Seacoast Dermatology involves the diagnosis and management of diseases affecting the skin, hair, and nails. The clinical team in Portsmouth addresses hundreds of different conditions, ranging from pediatric skin issues to geriatric dermatological care.

Management of Chronic Skin Conditions

Chronic conditions require long-term strategies that balance symptom relief with overall skin health. The Portsmouth clinicians specialize in treating several high-prevalence conditions:

  1. Acne and Rosacea: Beyond over-the-counter solutions, the practice provides medical-grade interventions, including prescription topicals, oral antibiotics, and isotretinoin therapy for severe cases. For rosacea, which causes persistent redness and visible blood vessels, providers utilize specialized light therapies and lifestyle management advice.
  2. Eczema and Dermatitis: Given the harsh winters in New Hampshire, many residents suffer from atopic dermatitis and contact dermatitis. The practice offers patch testing to identify allergens and provides advanced treatments like biologic injections for moderate-to-severe eczema.
  3. Psoriasis: This autoimmune condition requires sophisticated management. Seacoast Dermatology offers various modalities, including topical steroids, systemic medications, and narrow-band UVB light therapy, which can be highly effective for widespread plaques.

Specialized Treatments for Hair and Nail Disorders

Dermatology is not limited to the skin surface. The Portsmouth team also focuses on alopecia (hair loss) and onychomycosis (nail fungus). Hair loss evaluations often involve blood work and scalp biopsies to determine if the cause is hormonal, autoimmune, or environmental. Treatment plans may include topical minoxidil, oral medications, or platelet-rich plasma (PRP) therapy to stimulate follicle regrowth.

What is Mohs Surgery and Why Is It Offered in Portsmouth?

One of the most significant services provided at the Seacoast Dermatology Lafayette Road office is Mohs micrographic surgery. This specialized procedure is considered the most effective technique for removing the two most common forms of skin cancer: basal cell carcinoma and squamous cell carcinoma.

The Precision of the Mohs Technique

Unlike traditional excision, where a surgeon removes the visible tumor and a wide margin of healthy-looking skin, Mohs surgery is performed in stages. The surgeon removes the visible tumor along with a very thin layer of surrounding tissue. This tissue is immediately processed in the on-site lab and examined under a microscope.

If any cancer cells are detected at the edges of the tissue, the surgeon removes another thin layer only in the specific area where the cells remain. This process continues until no cancer cells are found. The primary benefits of this approach include:

  • Maximum Tissue Conservation: This is vital for areas where preserving healthy skin is functionally or aesthetically important, such as the nose, ears, and eyelids.
  • Highest Cure Rate: Mohs surgery offers a cure rate of up to 99% for new skin cancers and up to 94% for recurrent cancers.
  • Single-Visit Completion: The entire process, including the lab work and the final reconstructive repair, is typically completed in one day.

Expertise in Skin Cancer Detection

Regular skin cancer screenings are the foundation of preventive care at Seacoast Dermatology. Providers perform thorough full-body examinations to identify pre-cancerous lesions, such as actinic keratosis, before they evolve into invasive malignancies. Early detection through these annual screenings is the most effective way to prevent the need for more invasive surgeries later in life.

Aesthetic and Cosmetic Dermatology in the Seacoast Region

In addition to medical necessity, Seacoast Dermatology recognizes the importance of skin confidence and aesthetic health. The Portsmouth Borthwick Avenue office offers a suite of cosmetic procedures designed to enhance natural beauty and reverse the signs of environmental aging.

Injectable Treatments for Rejuvenation

The practice utilizes FDA-approved injectables to address volume loss and dynamic wrinkles. Neuromodulators like Botox are used to relax the muscles that cause forehead lines and crow's feet. Dermal fillers, such as those in the Juvéderm or Restylane families, are used to restore volume to the cheeks, lips, and nasolabial folds.

Laser and Energy-Based Therapies

Advanced laser technology allows Portsmouth clinicians to treat a variety of skin concerns with minimal downtime. These include:

  • Laser Hair Removal: Providing a long-term solution for unwanted hair on the face and body.
  • Vascular Lasers: Targeting redness, broken capillaries, and spider veins.
  • Fractional Resurfacing: Improving skin texture, reducing the appearance of scars, and minimizing fine lines by stimulating collagen production.
  • Microneedling and Chemical Peels: These treatments promote cell turnover and are effective for treating hyperpigmentation, acne scars, and dull skin tone.

The Impact of New Hampshire Weather on Skin Health

The Seacoast region presents unique challenges for skin maintenance. The clinicians at Seacoast Dermatology often emphasize the seasonal nature of skin care in Portsmouth.

Surviving the Cold New England Winter

During the winter months, humidity levels drop significantly in New Hampshire. Indoor heating further strips moisture from the skin, leading to "winter itch" and flares of chronic conditions like eczema and psoriasis. The practice recommends switching to heavier, cream-based moisturizers and avoiding hot showers that can further damage the skin barrier.

Sun Protection on the Coast

While Portsmouth residents are well-aware of sun risks during the summer at Hampton or Rye beaches, the practice warns against the dangers of cumulative sun exposure during the shoulder seasons. New Hampshire’s coastal environment can lead to significant UV damage even on overcast days. The high incidence of skin cancer in the region makes daily broad-spectrum SPF 30+ application a non-negotiable part of any skin health regimen recommended by the practice.

Preparing for Your Appointment at Seacoast Dermatology

Navigating a specialty medical visit is more efficient when patients arrive prepared. Seacoast Dermatology emphasizes a patient-centered approach, starting from the initial booking.

What to Bring to Your First Visit

Patients should arrive at the Portsmouth office with their insurance information and a valid form of identification. Additionally, it is helpful to provide:

  • A List of Current Medications: This includes both prescription and over-the-counter supplements, as many can affect skin health or surgical outcomes.
  • History of Previous Treatments: If a patient has seen other dermatologists or tried specific acne medications in the past, sharing these results helps the Portsmouth team refine the new treatment plan.
  • Clear Goals: Whether the visit is for a specific rash or a general desire for anti-aging, clearly stating the primary concern ensures the provider allocates sufficient time to address it.

Insurance and Payment Information

Seacoast Dermatology works with a wide range of insurance providers common in the New England area. However, insurance coverage for cosmetic procedures is rare, as these are typically considered elective. Patients are encouraged to verify their specific plan's requirements for specialist referrals before their scheduled appointment to avoid unexpected out-of-pocket costs.

Why Choose a Physician-Led Local Practice?

In an era where many medical practices are being absorbed by large national conglomerates, Seacoast Dermatology remains a locally owned and physician-led entity. This structure offers several advantages for Portsmouth patients.

Community-Focused Care

The providers and staff live and work in the Seacoast community. This local connection fosters a deeper understanding of the environmental and lifestyle factors that affect the skin of Portsmouth residents. The practice has deep roots in the area, having served multiple generations of families over its 40-year history.

Academic Affiliations and Continued Education

While maintaining a local feel, the practice is affiliated with regional academic institutions. This ensures that the clinical team stays at the forefront of dermatological research and emerging treatments. Many of the physicians contribute to medical textbooks and scholarly journals, bringing high-level expertise to a community setting.

How to Schedule an Appointment in Portsmouth

Accessing care at Seacoast Dermatology is straightforward. New and returning patients can contact the central scheduling line for the Portsmouth offices.

  • Phone: (603) 431-5205
  • Clinical Hours: Monday through Thursday from 8:00 AM to 5:00 PM, and Friday from 8:00 AM to 4:00 PM.
  • Online Inquiries: The practice website provides a portal for non-urgent inquiries and information regarding patient forms.

For urgent skin concerns, such as a rapidly changing mole or a severe, painful rash, patients should specify the nature of the urgency to the scheduling team to facilitate a more immediate evaluation.

Is Mohs surgery performed every day at the Portsmouth Lafayette Road suite?

Mohs surgery is scheduled on specific days when the Mohs surgeon and the laboratory team are on-site. Patients should confirm their surgical date and location with the scheduling coordinator, as surgery may also be performed at the Exeter location depending on the week.

What should I do if I have a skin emergency outside of office hours?

For life-threatening emergencies, patients should always call 911 or visit the nearest emergency room, such as Portsmouth Regional Hospital. For urgent dermatological issues after hours that are not life-threatening, patients can call the main office line to receive instructions on how to reach the on-call provider or leave a message for the next business day.

Can I get Botox and a skin check during the same appointment?

In many cases, providers can address both medical and cosmetic concerns during the same visit at the Borthwick Avenue location, provided there is enough time scheduled. However, it is important to mention both needs when booking the appointment so the appropriate amount of time can be allocated.

Does the practice offer telehealth appointments for Portsmouth residents?

Telehealth services may be available for certain types of follow-up visits or consultations that do not require a physical procedure or hands-on examination. Patients interested in a virtual visit should inquire during the scheduling process to see if their specific concern is eligible for a telehealth platform.
