Frequently Asked Questions
Physician-led medical aesthetics clinic offering neuromodulators (botox), dermal fillers, microneedling, and selective laser/energy resurfacing to enhance your natural beauty.
Skin Rejuvenation in Oakville
Key point: Skin rejuvenation makes your skin look better and healthier. It boosts collagen and cell turnover for smoother, firmer, and more even skin.
As a doctor in Oakville, I use non-surgical treatments. These help your skin renew itself. They soften fine lines, improve elasticity, and refine tone and texture.
These approaches promote collagen remodeling and healthier barrier function for a youthful glow that still looks like you
Key point: We provide physician-led injectables (Botox®/neuromodulators, dermal fillers) and advanced skincare (microneedling, selective laser/energy resurfacing) tailored to your goals.
In your consultation, I examine your skin and map a plan that may combine treatments for best—and safest—results. Chemical peels remove damaged outer layers from the skin. Lasers and energy devices help build deeper collagen for firmness and better texture. Injectables smooth out lines and add volume for a balanced, natural loo
Neuromodulators & Fillers
Key point: Botox works by relaxing the muscles responsible for wrinkles. Effects typically become visible within 3 to 7 days and persist for approximately 3 to 4 months.
By reducing repetitive muscle movement in areas like frown lines and crow’s feet, skin looks smoother. We keep your expressions natural by performing the treatment meticulously.
Expect near-full effect at ~14 days and maintenance about 3–4 months later.
Key point: Indeed, fillers instantly increase volume. They can last from several months to years, depending on the product and area.
HA and other fillers can lift cheeks, soften folds, and refine lips or jawline with minimal downtime.
Duration varies by formulation, injection depth, and your metabolism; I’ll recommend options to balance subtlety and staying power.
Key point: Discomfort is brief and usually minimal; modern fillers include lidocaine and we use numbing and gentle technique.
Expect quick pinches for Botox and controlled pressure for fillers. Most clients return to normal activities immediately after treatment.
Advanced Skin Care & Resurfacing
Key point: Yes—resurfacing lasers create controlled injury that triggers new collagen, improving firmness, lines, and scars.
We use energy settings that match your skin type. This helps improve texture and safely reduce pigment. Aftercare focuses on keeping your skin moist and protected from the sun for the best healing.
Key point: Critical—keeping skin moist post-procedure and practicing strict sun protection speeds recovery and protects results.
I will provide you with a comprehensive and personalized skincare plan tailored specifically to your needs. This plan will use occlusives.
These are moisturizing agents that form a barrier on the skin. This barrier helps prevent moisture loss. These ingredients are essential for maintaining hydration and supporting the skin's natural barrier function.
I will also suggest gentle cleansers. These products clean the skin without removing its natural oils.
These cleansers will help remove dirt and makeup. They keep your skin balanced and comfortable. This reduces the chance of irritation or dryness.
Furthermore, I will emphasize the importance of incorporating a daily broad-spectrum sunscreen into your routine. This sunscreen will protect your skin from UVA and UVB rays. These rays can cause early aging and increase the risk of dark spots.
Using a broad-spectrum SPF every day protects your skin from sun damage. It also keeps your complexion healthy and looking good.
These parts of your personalized skincare plan will work together. They will help repair your skin barrier, improve hydration, and lower the chances of problems like hyperpigmentation. By following this tailored approach, you can achieve healthier, more resilient skin over time.
Safety, Process & Credentials
Key point: Training, anatomy expertise, and judgement matter—doctor-supervised care maximizes safety and natural-looking outcomes.
As a doctor in Oakville, I perform or supervise your treatments. I follow proven methods that fit your skin and goals.
Key point: We look at your history, check your skin, set realistic goals, and create a personal plan—no pressure.
You’ll leave with clear options, downtime expectations, and costs so you can decide confidently.
Key point: Most treatments have little to no downtime; stronger peels/lasers may require a few recovery days.
We can stage or soften treatments to fit work and family schedules.
Services We’re Asked About (That We Don’t Provide)
Key point: No, we do not offer laser hair removal at Merrion. However, we can recommend trusted local providers if you need it.
We’re a medical aesthetics clinic focused on rejuvenation (injectables, advanced skincare, resurfacing).
To reduce hair, professional laser hair removal can help. It offers long-term results after several sessions.
Talk to a qualified clinic about your suitability. They will consider your skin and hair type, medications, and sun exposure. We’ll gladly point you to reputable options in Oakville.
Key point: No, we do not offer hair restoration here. However, we can refer you to medical practices that do this safely and effectively.
If you are looking into PRP or surgery, we can help you find certified providers. They focus on scalp treatments, so you can compare your options and what to expect. (We keep our scope to skin rejuvenation for the face and body.)
Booking & Practicalities
Key point: Yes, it's a complimentary, stress-free consultation with me (Dr. Kate). You can schedule online or call the clinic.
Please bring your questions, current products, and any past treatment information. We will make a plan that fits your goals, budget, and schedule.
Key point: No—we’re a single, physician-led Oakville clinic, not a multi-location chain.
That’s by design: it lets me provide attentive, personalized care with licensed nurses and a close-knit medical team.
Skin Health & Cancer Awareness
Key point: If I notice something concerning, I will look into it.
I will suggest next steps for you to take with your doctor. Your health is the most important thing.
Key point: Yes—use gentle, non-irritating products and daily broad-spectrum SPF; this protects results and prevents sun damage.
Dermatologists stress that consistent sun protection reduces risks of skin cancer and premature aging. We’ll tailor a simple regimen for you.
