Ready for a calmer, long‑term approach to melasma?

Melasma Treatment in Oakville

Melasma is a common (and often stubborn) form of pigmentation that can appear as soft, patchy brown or grey‑brown areas—most often on the cheeks, forehead, or upper lip. Many patients describe it as frustrating because it can fade and return, and it often doesn’t behave like simple sun spots.

Unlike isolated dark spots, melasma is typically influenced by multiple triggers—including UV exposure, heat, hormonal shifts, and inflammation. Because melasma can flare when the skin is irritated or over‑treated, the safest results often come from a gentle, stabilising plan that supports the skin barrier and focuses on long‑term control.

At Merrion Medical Aesthetics in Oakville, Dr. Kate Healy approaches melasma with care, consistency, and realistic goals. Treatment may include medical‑grade skincare, pigment‑regulating serums, and carefully calibrated laser resurfacing—often supported through a structured approach like the Merrion Melasma Control Program.

Common Areas Affected

Cheeks (diffuse patchy pigment)

Cheeks are one of the most common areas for melasma, often appearing as broader “fields” of pigmentation rather than individual spots. A thoughtful treatment plan focuses on calming the skin, supporting barrier health, and gradually improving brightness to reduce visible contrast.

Forehead & temples

Forehead melasma can be triggered by sun exposure and heat, and it often shifts subtly over time. In clinic, we prioritise gentle, low‑inflammatory strategies and reinforce daily protection—because consistency is what helps keep melasma stable.

Upper lip (“moustache shadow”)

Upper‑lip melasma is common and can feel especially noticeable in everyday life. This region tends to be sensitive, so treatment needs to be measured and well‑supported with appropriate home care to minimise irritation and rebound pigment.

Jawline & lower face

For some patients, melasma extends to the jawline or chin—especially when there’s a hormonal component. When this happens, we take a whole‑face view and build a plan that supports even tone while protecting the skin’s resilience over time.

Frequently Asked Questions

What is melasma?

Melasma is a form of hyperpigmentation that tends to appear as diffuse, patchy brown or grey‑brown areas on the face. It’s often influenced by sun exposure, heat, hormones, and inflammation. Because it behaves differently than sun spots, treatment needs a more measured, long‑term approach.

What triggers melasma flare‑ups?

Common triggers include UV exposure, heat, hormonal shifts, and skin irritation/inflammation. Many people notice melasma becomes more visible in summer or during hormonal transitions. Identifying triggers helps guide a plan that focuses on stability—not quick fixes.

What’s the difference between melasma and sun spots?

Sun spots (often called lentigines) tend to be more discrete and “spot‑like.” Melasma is usually more diffuse and can look like soft patches. The difference matters because melasma is more prone to rebound if it’s treated too aggressively.

Can laser make melasma worse?

It can—if the treatment is too aggressive or creates too much heat/inflammation for your skin. That’s why melasma requires careful settings, appropriate skin preparation, and good post‑care. Dr. Kate will discuss whether laser is suitable for you and, if so, the safest way to approach it.

How long does it take to see improvement in melasma?

Melasma typically improves gradually. Most patients benefit from a series‑based plan alongside consistent home care. The goal is steady progress and better control over time, rather than “erasing” pigment quickly—which can increase the risk of rebound.

Do I need a prescription to treat melasma?

Not always, but many effective melasma routines include medical‑grade products and—sometimes—prescription options. Dr. Kate will review your skin and discuss what’s appropriate for you, based on your goals, sensitivity level, and overall skin health.
