• 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.
• Platelet-Rich Plasma (PRP) Therapy (for Skin Rejuvenation & Hair Loss): Utilizing a concentration of a patient's own platelets to promote tissue repair and regeneration, used for facial rejuvenation (e.g., with microneedling) and to stimulate hair growth in certain types of alopecia.

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

Medically necessary consultations with a licensed Dermatologist like Dr. Provost, 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. Provost'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. Provost, 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. Provost. 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.

What does a Dermatologist like Dr. Provost specialize in?

A Dermatologist, such as Dr. Provost, 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. Provost offers various medical, surgical, and potentially cosmetic treatments depending on their practice focus.

Dr. Provost 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. Provost's office or self-administered at home) or intravenous (IV) infusion. Dr. Provost would discuss the specific biologic, its benefits, potential side effects, and monitoring requirements if it's a suitable option for you.

What kind of sunscreen does Dr. Provost recommend?

While specific brand recommendations can vary, Dr. Provost would likely advise choosing a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. For daily use, a lighter formulation might be preferred, while for prolonged outdoor activities, water-resistant sunscreen is important. Consider your skin type: individuals with sensitive skin might prefer mineral-based sunscreens containing zinc oxide or titanium dioxide. The most important thing is to apply sunscreen generously and reapply it every two hours, or more often if swimming or sweating. Dr. Provost can provide personalized recommendations based on your skin type and lifestyle during your consultation.

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

The recommended frequency for skin cancer screenings by a Dermatologist like Dr. Provost 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. Provost 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.

When should someone consider seeing a Dermatologist like Dr. Provost?

A referral to a Dermatologist like Dr. Provost is often recommended by a family physician for: any new or changing moles or skin growths; persistent or severe skin rashes (e.g., eczema, psoriasis) not responding to initial treatments; severe or cystic acne; chronic hives; significant hair loss or scalp disorders; problematic nail conditions (e.g., persistent fungal infections, unusual changes); suspected skin infections; or for expert skin cancer screening, especially if you have risk factors like a personal or family history of skin cancer, numerous moles, or significant sun exposure. Early consultation can be key for effective management and diagnosis.
