If you've noticed patches of darker skin on your cheeks, forehead, or upper lip that won't fade no matter what cream you try, you're not alone — and it isn't just "stubborn pigmentation." You may be dealing with melasma, one of the most common and most misunderstood skin conditions affecting women (and some men) in the UK. This guide to melasma treatment UK options will help you understand what melasma is, why it happens, and which evidence-based treatments actually work — along with how to get expert dermatology input without spending months on a waiting list.
Melasma is a form of hyperpigmentation that shows up as symmetrical, brown or grey-brown patches, most often on sun-exposed areas of the face — the cheeks, forehead, nose, chin, and upper lip. Dermatologists sometimes call it "chloasma" or the "mask of pregnancy" because it so frequently appears during or after pregnancy, when oestrogen and progesterone levels shift dramatically.
According to the British Association of Dermatologists, melasma is far more common in women than men, and it affects people of all skin tones, though it is particularly common in people with medium to darker skin types. The patches are harmless — they don't itch, hurt, or become cancerous — but they can have a real emotional impact and are notoriously difficult to treat without the right approach.
Key signs of melasma include:
If a new patch is only on one side of the face, itches, bleeds, or changes rapidly, it probably isn't melasma. That's a good reason to have it reviewed by a skin expert rather than self-diagnose.

Melasma is what dermatologists call "multifactorial" — there's rarely a single cause. Instead, several triggers work together to push pigment-producing cells (melanocytes) into overdrive.
The main drivers include:
Hormonal changes. Pregnancy, combined oral contraceptives, the hormonal coil, HRT, and fertility treatments are all well-known triggers. Roughly a quarter of women with melasma link it to hormonal medication or pregnancy.
Ultraviolet and visible light. Even small amounts of UV — and visible light from the sun, screens, and bright indoor lighting — stimulate melanocytes. This is why melasma almost always worsens in summer and can flare even on cloudy days.
Genetics. Up to half of people with melasma have a close relative with the condition. If your mother or sister has it, your risk is higher.
Heat. Hot yoga, saunas, and even cooking over a hot hob can aggravate melasma, independent of UV exposure.
Certain medications and products. Some photosensitising drugs and fragranced or irritating skincare can worsen pigmentation.
Understanding your triggers matters because melasma is a chronic, relapsing condition. Treatment that ignores the trigger will almost always fail.
There is no single "cure" for melasma, but a layered approach can dramatically improve the appearance of the patches. Most UK dermatologists follow a stepwise plan that combines rigorous sun protection, prescription-strength topicals, and — in resistant cases — in-clinic procedures.
Daily broad-spectrum sun protection. Sunscreen is the foundation of every serious melasma treatment UK plan. Look for SPF 50, broad-spectrum UVA/UVB cover, and ideally a tinted mineral sunscreen containing iron oxides, which also block visible light. Reapply every two hours when outdoors.
Topical prescriptions. Hydroquinone remains the "gold standard" lightening agent and is typically used for short courses under dermatology supervision. A popular combination is hydroquinone with tretinoin and a low-potency steroid (sometimes prescribed as Pigmanorm). Alternatives, particularly for pregnancy or long-term use, include azelaic acid, tranexamic acid (topical or oral), kojic acid, niacinamide, and cysteamine.
Chemical peels. Cosmelan and dermamelan depigmenting peels are used by many UK clinics for stubborn melasma, usually alongside a home care regimen.
Laser and energy-based devices. Picosecond and low-fluence Q-switched lasers can be effective in some patients, but melasma is famously unforgiving — aggressive lasers can actually make pigmentation worse, so these treatments should only be done by specialists experienced in treating melasma specifically.
Around 60–70% of patients see meaningful improvement with combination therapy, but melasma often relapses and requires ongoing maintenance. That's why having a clear plan and access to expert review matters far more than chasing the "latest" cream online.

If your GP thinks your pigmentation needs specialist review, you can be referred to an NHS consultant dermatologist — but waiting times in many parts of the UK now stretch from several months to well over a year. For a condition like melasma, where the wrong treatment can worsen the patches, that's a long time to be guessing.
A pragmatic route is to get a fast triage first: an expert opinion on whether your patches are truly melasma, what's likely driving them, and which treatments are safe to start. That's exactly what Hebra is built for. Hebra's skin health triage app analyses a photo of your skin, screens for red flags, and connects you directly to a dermatologist for review — cutting the wait from months to days.

Melasma isn't a condition you "beat" in one round of treatment. Think of it more like managing eczema or rosacea — a long-term relationship with your skin where daily habits matter as much as any prescription. The good news is that with the right plan, most people can fade their patches significantly and keep them under control.
A realistic long-term routine usually includes daily tinted SPF 50, gentle non-irritating skincare, antioxidants in the morning (such as vitamin C), a prescription lightener in the evening during active treatment phases, and a maintenance regimen of azelaic acid or niacinamide. Hormonal reviews with your GP may also be worthwhile if you suspect your contraception or HRT is playing a role — never stop prescribed medication without medical advice.
Perhaps most importantly, be kind to yourself. Melasma is deeply tied to hormones and genetics — it's not a sign that you've "done something wrong" to your skin.
If you're tired of guessing whether your pigmentation is melasma, sun damage, or something else entirely, you don't have to wait months for answers. Hebra's AI-powered skin triage gives you a fast, dermatologist-backed review of your skin — so you can start the right treatment sooner and avoid the mistakes that make melasma worse.
