Melasma In Summer: Why It Keeps Coming Back And What Actually Works
If you’ve ever felt like your melasma improves during winter only to return the moment summer arrives, you’re certainly not alone.
At Dr Liesel Medical Aesthetics, Bromley we often see patients who have spent months successfully managing pigmentation, only to notice those familiar patches gradually darkening again as the weather warms up. For many people, melasma can feel frustratingly persistent. Even when it appears to fade, it rarely behaves like ordinary pigmentation.
The reality is that melasma is one of the most complex skin conditions we treat. It is influenced by multiple internal and external factors, and summer creates the perfect environment for flare-ups.
The good news is that effective melasma treatment does exist. The key is understanding why melasma develops, why it returns, and which treatments can genuinely help control it long-term.
What Is Melasma And Why Does It Often Worsen In Summer?
Melasma is a chronic pigmentation condition that causes patches of darker skin, most commonly on the cheeks, forehead, upper lip, chin and jawline. It develops when pigment-producing cells within the skin become hyperactive and overproduce melanin – a process driven not just by sun exposure, but also by hormonal changes and genetic predisposition. This combination of triggers, together with its symmetrical, diffuse pattern, is what sets melasma apart from ordinary sun-induced pigmentation such as sun spots.
The condition often becomes more noticeable during the summer months because melanocytes are highly sensitive to environmental triggers. While UV exposure is a well-known cause, many patients are surprised to learn that heat and visible light can also stimulate pigment production.
This means that everyday activities such as driving, sitting near windows, walking outdoors or simply spending time in warm weather can contribute to melasma flare-ups. As a result, some patients notice their pigmentation becoming darker despite wearing SPF regularly.
Because melasma behaves differently from other forms of pigmentation, successful management requires a tailored approach that addresses both the visible pigmentation and the factors that trigger it.
Melasma is rarely caused by a single factor. In most cases, a combination of environmental, hormonal and genetic influences contribute to ongoing pigmentation, as shown below.

What Is The Best Melasma Treatment?
There is no single treatment that works for every patient.
Treatment choice depends on several factors, including:
- Severity of pigmentation
- Depth of pigment within the skin
- Skin type
- Previous treatment history
- Lifestyle factors
- Individual triggers
For milder cases we would usually start by improving skin health, introducing pigment-regulating skincare, and focusing heavily on prevention.
For more established melasma, a combination approach often delivers the most reliable results.
At Dr Liesel Medical Aesthetics in Chislehurst, Bromley, treatment plans are tailored to the individual rather than relying on a one-size-fits-all protocol.
Why Cosmelan® Is Often Considered The Gold Standard For Melasma
One of the most effective treatments available for melasma is Cosmelan®. Unlike many pigmentation treatments that focus solely on removing existing pigment, Cosmelan® works by regulating the production of pigment itself.
This distinction is important.
Many treatments can lighten visible pigmentation temporarily. Cosmelan® is designed to address the biological pathways responsible for excess pigment formation, making it particularly valuable for recurrent melasma.
The treatment begins with a 4-6 week structured homecare programme, followed by an in-clinic depigmentation mask followed by a continued structured homecare programme. Over time, excess pigmentation gradually fades while future pigment production is better controlled.
Patients often notice:
- Improved skin clarity
- More even skin tone
- Reduced patchy pigmentation
- Brighter overall complexion
- Better long-term pigment control
Because melasma is notoriously difficult to manage, Cosmelan® is frequently recommended when patients have tried multiple products without achieving lasting improvement.
Can Alma Harmony XL Pro Help Melasma?
Energy-based treatments can sometimes play a role in managing pigmentation, but careful patient selection is essential.
The Alma Harmony XL Pro platform offers advanced technologies that can address certain types of pigmentation while also improving overall skin quality.
However, melasma requires a cautious approach.
In clinic, we often see patients who have undergone aggressive laser treatments elsewhere and subsequently experienced worsening pigmentation. This is because excessive heat can sometimes trigger melanocytes rather than calm them.
When Alma Harmony XL Pro is used as part of a carefully planned treatment strategy, it may help address associated pigmentation concerns and improve skin appearance. Treatment suitability always depends on the individual presentation and skin assessment.
For this reason, a thorough consultation is particularly important before considering energy-based treatments for melasma.
Why Medical Grade Skincare Matters
One of the biggest reasons melasma returns is inconsistent home management.
Professional treatments can create excellent improvements, but maintaining results requires ongoing support.
Medical grade skincare is often the foundation of successful melasma treatment because it helps regulate pigment production between treatments.
A carefully selected programme may include ingredients designed to:
- Inhibit melanin production
- Improve skin cell turnover
- Reduce inflammation
- Support barrier function
- Enhance overall skin health
Patients are often surprised to learn that daily skincare can have a significant impact on long-term pigment control.
Can Skin Regeneration Treatments Improve Melasma-Prone Skin?
Regenerative treatments can play an important supporting role.
Treatments such as MCT Exosomes, Polynucleotides, PRP, Skinvive and Rexonage®3 focus on improving skin health, resilience and repair mechanisms.
In more advanced cases, we would normally look at the overall condition of the skin rather than focusing exclusively on pigmentation.
Healthier skin often responds more predictably to treatment and may be less prone to inflammation, which is an important consideration when managing melasma.
Rexonage®3 is particularly interesting because it supports regenerative processes without heat or tissue damage, making it suitable for patients seeking skin rejuvenation while avoiding unnecessary thermal stimulation.
Why SPF Is Non-Negotiable For Melasma
No melasma treatment plan is complete without sun protection.
Even the most advanced treatment cannot compete with ongoing UV exposure.
Patients with melasma should generally wear broad-spectrum SPF daily, regardless of the season.
This includes:
- Sunny days
- Cloudy days
- Working near windows
- Driving
- Outdoor exercise
Many patients benefit from reapplying SPF throughout the day, particularly during summer.
Without consistent sun protection, even excellent treatment results can be difficult to maintain.
The Importance Of A Personalised Treatment Plan
One of the reasons melasma can be so challenging is that every patient presents differently.
Some patients have predominantly hormonal triggers. Others have significant sun-induced components. Some have superficial pigmentation, while others have deeper dermal involvement.
This is why successful melasma treatment rarely follows a standard formula.
Instead, treatment plans are typically built around:
- Pigment severity
- Skin sensitivity
- Previous treatment history
- Lifestyle factors
- Long-term maintenance requirements
A personalised approach allows treatments to be adjusted as the skin changes over time, helping patients achieve more sustainable results.
Frequently Asked Questions About Melasma
Can melasma disappear permanently?
Melasma can often be significantly improved, but because it is a chronic condition, ongoing maintenance is usually required to prevent recurrence.
Is melasma caused by sun exposure alone?
No. Sunlight is a major trigger, but hormones, genetics, heat and inflammation can all contribute.
Does melasma get worse with age?
Not necessarily. Some patients find it stabilises over time, while others experience flare-ups related to hormonal changes or cumulative sun exposure.
Is Cosmelan® suitable for all skin types?
Cosmelan® is widely used across different skin types and is particularly valued for treating stubborn pigmentation and melasma. Suitability should always be assessed during consultation.
How long does melasma treatment take?
Most patients begin seeing improvement within weeks, but managing melasma is usually a longer-term process that requires ongoing maintenance and prevention.
Can I have melasma treatment during summer?
Yes. However, treatment selection, sun protection and aftercare become especially important during periods of increased UV exposure.
