Dr. Catherine Tremblay diagnoses and treats a wide range of skin, hair, and nail conditions, including:

Skin Cancers, Precancerous Lesions & Benign Growths

Nail Disorders (Onychopathies)

• Nail Psoriasis: Psoriasis affecting the fingernails and toenails, causing pitting, discoloration (oil drop sign), thickening, onycholysis (separation from bed), and subungual hyperkeratosis.
• Beau's Lines & Other Nail Dystrophies: Transverse depressions in the nails (Beau's lines) or other changes in nail texture or appearance that can indicate systemic illness, trauma, or nutritional deficiencies.

Acne, Rosacea & Follicular Disorders

• Hormonal Acne / Adult Female Acne: Acne linked to fluctuations in hormones, often presenting in adult women along the jawline, chin, and neck, and may persist beyond teenage years.
• Acne Scars (Atrophic, Hypertrophic, Keloidal): Permanent textural changes and indentations (atrophic), raised scars (hypertrophic), or overgrown scars (keloidal) that can result from severe or picked acne.
• Acne Vulgaris (Comedonal, Papulopustular, Nodulocystic): A common skin condition characterized by pimples, blackheads, whiteheads, and sometimes deeper cysts and nodules, occurring when hair follicles become clogged with oil and dead skin cells. Severity can vary.

This list is not exhaustive. For personalized advice regarding your specific dermatological condition, please consult with Dr. Catherine Tremblay.

• Body Contouring & Skin Tightening (e.g., Cryolipolysis, Radiofrequency, Ultrasound): Non-invasive or minimally invasive procedures designed to reduce localized fat deposits (e.g., CoolSculpting®) or tighten lax skin on the face and body (e.g., Thermage®, Ultherapy®).
• Hyperhidrosis (Excessive Sweating) Treatment (Topical, Oral, Botulinum Toxin): Management options for excessive sweating of the underarms, palms, or soles, including prescription antiperspirants, oral medications, and botulinum toxin injections.
• Chemical Peels (Superficial, Medium, Deep - Glycolic, Salicylic, TCA, Phenol): Application of chemical solutions to exfoliate the skin and improve texture, tone, and appearance by treating acne, sun damage, pigmentation, and fine lines. Peel depth varies by agent and concentration.
• Excision of Benign Lesions (Moles/Nevi, Cysts, Lipomas, Skin Tags, Seborrheic Keratoses): Surgical removal of non-cancerous skin growths for medical reasons (e.g., irritation, inflammation) or cosmetic purposes, with pathological examination if indicated.
• Hidradenitis Suppurativa Management (Medical, Interventional, Biologics): Medical (antibiotics, retinoids), interventional (incision & drainage, deroofing), and biologic therapy for a chronic inflammatory skin condition causing painful lumps, abscesses, and sinus tracts in skin folds.
• Eczema (Atopic, Contact, Seborrheic Dermatitis) Management: Treatment plans for various types of chronic inflammatory skin conditions like eczema, focusing on reducing inflammation, relieving itch, restoring skin barrier function, and preventing flare-ups with topical steroids, non-steroidal topicals, phototherapy, and systemic agents including biologics.
• Medical-Grade Facials & Skincare Consultations: Professional facial treatments tailored to specific skin concerns and expert advice on developing an optimal at-home skincare regimen using medical-grade products.

Are consultations and dermatological treatments with Dr. Tremblay, a Dermatologist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations with a licensed Dermatologist like Dr. Tremblay, diagnostic procedures (e.g., skin biopsies), and treatments for provincially insured skin conditions (e.g., psoriasis, severe eczema, skin cancer, infections) are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC when a referral from a family doctor is in place. Purely cosmetic procedures (e.g., Botox for wrinkles, most laser hair removal, fillers for aesthetic enhancement) are typically not covered and are self-pay. It's crucial to discuss coverage specifics for any proposed treatment with Dr. Tremblay's office or Régie de l'assurance maladie du Québec (RAMQ) beforehand, especially if there's a potential cosmetic component.

Do I need a referral to see Dr. Tremblay, a Dermatologist?

Yes, for medically necessary dermatological care covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an ER doctor for an acute issue) is almost always required to see a Dermatologist such as Dr. Tremblay. This ensures coordinated care and that your visit is appropriate for specialist assessment. Some dermatologists may offer consultations for uninsured cosmetic services without a referral, but these would be a direct cost to you. Always check with the clinic regarding their specific referral policy.

How should I prepare for my first dermatology appointment with Dr. Tremblay?

To make the most of your first visit with Dr. Tremblay, it's helpful to: 1. Make a list of your skin concerns, symptoms (e.g., itch, pain, duration), and any treatments you've already tried (both prescription and over-the-counter). 2. Bring a list of all your current medications, including vitamins and supplements. 3. Be prepared to discuss your personal and family medical history, including any history of skin cancer or significant skin conditions. 4. For a full skin exam, it's best to wear loose, comfortable clothing that is easy to remove and avoid wearing makeup or nail polish. 5. If your concern involves a rash that comes and goes, taking clear photos when it's visible can be very helpful. 6. Write down any questions you have for Dr. Tremblay.

How often should I see a Dermatologist like Dr. Tremblay for skin cancer screening?

The recommended frequency for skin cancer screenings by a Dermatologist like Dr. Tremblay varies based on your individual risk factors. These include a personal or family history of skin cancer (especially melanoma), having many moles (e.g., >50) or atypical moles, fair skin that burns easily, a history of excessive sun exposure or tanning bed use, or a suppressed immune system. Your family doctor can assess your risk, or Dr. Tremblay can provide a personalized recommendation after an initial consultation. Regardless of professional check-ups, performing monthly self-skin exams to monitor for any new or changing lesions (using the ABCDEs of melanoma as a guide) is crucial for early detection.

What does a Dermatologist like Dr. Tremblay specialize in?

A Dermatologist, such as Dr. Tremblay, is a medical doctor with highly specialized training in diagnosing and treating over 3,000 conditions affecting the skin, hair, and nails in patients of all ages – from newborns to seniors. This includes a wide spectrum of diseases from common issues like acne, eczema, and psoriasis, to more complex conditions like skin cancer, autoimmune skin disorders (e.g., lupus, pemphigus), severe allergic reactions, and genetic skin diseases. She is a Dermatologist specializing in the comprehensive medical and surgical care of skin, hair, and nail conditions. Dr. Tremblay offers various medical, surgical, and potentially cosmetic treatments depending on their practice focus.

Dr. Tremblay mentioned biologics. What are they for skin conditions?

Biologic medications are a newer class of treatments for moderate to severe inflammatory skin conditions like psoriasis, eczema (atopic dermatitis), and hidradenitis suppurativa, when other treatments haven't been effective enough. Unlike traditional systemic drugs that suppress the broader immune system, biologics are proteins engineered to target very specific parts of the immune system that cause inflammation in these diseases. They are usually given by injection (either by Dr. Tremblay's office or self-administered at home) or intravenous (IV) infusion. Dr. Tremblay would discuss the specific biologic, its benefits, potential side effects, and monitoring requirements if it's a suitable option for you.

What is the difference between a Dermatologist and an Esthetician?

A Dermatologist, like Dr. Tremblay, is a medical doctor (MD) who has completed medical school followed by several years of specialized residency training in dermatology. They are qualified to diagnose and treat over 3,000 diseases of the skin, hair, and nails, prescribe medications, perform surgical procedures (like skin cancer removal), and manage complex skin conditions. An Esthetician (or Aesthetician) is a skincare professional trained in cosmetic skin treatments and services that improve the appearance of the skin, such as facials, superficial chemical peels, microdermabrasion, waxing, and makeup application. They are not medical doctors and cannot diagnose skin diseases, prescribe medications, or perform medical or surgical procedures.
