Melasma: Why It Comes Back and What Actually Works

Melasma is the most frustrating form of pigmentation we see in clinic. It looks like ordinary sun damage but behaves nothing like it, and treating it like sun damage usually makes it worse. Clients arrive having tried over-the-counter brightening creams, aggressive home peels, even unsupervised laser treatments - and almost always with patches that have darkened or spread.

Melasma is manageable. The condition is not curable in the way an acute skin issue is curable, but with the right combination of protection, topical actives and gentle in-clinic interventions, most clients reach 70 to 90 percent clearance and stay there with maintenance.

What melasma actually is

Melasma is hormone-driven hyperpigmentation. It is triggered by oestrogen and progesterone fluctuations - pregnancy, the contraceptive pill, hormonal IUDs, perimenopause - and amplified by UV light, visible light, and even heat. Genetics load the gun; hormones and sun pull the trigger.

Classic presentation: symmetrical brown or grey-brown patches across the cheeks, forehead, upper lip, and jawline. Worse in summer, better in winter, never quite gone. The pigmentation can sit in the epidermal (surface), dermal (deeper) or mixed layer, and the depth dictates which treatments will and will not work.

Why it disproportionately affects darker skin

Fitzpatrick III, IV and V skin types have higher baseline melanin activity, which means melasma can present more strongly and respond less predictably to aggressive interventions. The same treatments that work on Fitzpatrick I or II skin can rebound on darker skin, creating post-inflammatory hyperpigmentation that compounds the original problem.

Why aggressive treatment backfires

Melasma sits in two layers - epidermal (surface) and dermal (deeper). Aggressive lasers, harsh peels, and IPL can trigger inflammation that drives more pigment production, leaving you worse off than when you started. The rule with melasma is patience and gentleness. Any practitioner offering "one-session melasma removal" with aggressive resurfacing is either inexperienced or actively dangerous.

What works

• Daily broad-spectrum SPF 50 - including iron oxide in tinted sunscreen, which blocks visible light. Non-negotiable. UV protection alone is not enough; visible light from sunlight, screens and indoor lighting also drives melasma activity.
• Topical actives - tranexamic acid, niacinamide, azelaic acid, vitamin C, kojic acid, and prescription tyrosinase inhibitors such as hydroquinone (cycled, not continuous)
• Gentle, layered chemical peels - the Mela-Vita Peel, formulated specifically for hyperpigmentation including hormonal melasma, layers four acids and two anti-inflammatory botanicals to calm and brighten without aggressive resurfacing
• Skin barrier support - inflammation drives melasma, so a healthy barrier matters. Ceramide-rich moisturisers and a minimal gentle routine outperform heavy active layering for most melasma clients
• Microneedling at appropriate depth - controlled, careful, never on inflamed skin

What to avoid

• Hot showers on the face - heat alone activates melanocytes
• Steam rooms, saunas, heated yoga
• Strong physical exfoliants and aggressive scrubs
• IPL unless your therapist has confirmed it is safe for your specific presentation
• Tanning - even one sunny weekend can undo months of progress
• Inadequate sun protection - SPF 30 is not enough for melasma management
• "Whitening" products from informal markets - many contain unregulated mercury or steroids that wreck skin long-term

The hormonal angle

For some clients, the most powerful intervention is hormonal. Coming off the combined contraceptive pill or switching from a hormonal IUD can dramatically improve melasma over six to twelve months. This is a conversation for the client's GP or gynaecologist; we can flag it but not prescribe it. For perimenopausal clients, hormone replacement therapy choices may also influence pigmentation.

Pregnancy and post-pregnancy melasma

Melasma that emerged during pregnancy ("the mask of pregnancy") often improves on its own in the months after delivery, particularly if breastfeeding ends and the cycle re-regulates. We typically recommend gentle in-clinic care during this window - daily SPF, niacinamide, vitamin C - while waiting to see how much resolves naturally. Aggressive intervention during the early postpartum period often does more harm than good.

The role of visible light

Visible light exposure is the most underestimated melasma trigger. Standard mineral sunscreens with iron oxide block visible light effectively; chemical sunscreens largely do not. Tinted sunscreens are the practical solution - the iron oxide pigment delivers visible light protection while the chemical or mineral filters cover UV. Heliocare 360, Sesderma and Lamelle Helase ranges all carry tinted iron-oxide formulations.

Realistic expectations

Melasma is managed, not cured. Maintenance is for life. Done right, you can get to 80 percent clearance and stay there. The combination that works for most clients in our chair: daily SPF 50 with iron oxide, vitamin C in the morning, niacinamide and prescription brightener at night, monthly Mela-Vita treatment for the active phase tapering to maintenance every three months.

The first consultation

The consultation focuses on three things: identifying the trigger pattern, mapping the depth and distribution of the pigmentation, and building a realistic six-month plan. We document with high-resolution photographs and Wood's lamp examination so progress is measurable rather than subjective. Most clients see meaningful improvement within twelve weeks of starting the right protocol.
