Pigmentation and melasma treatment in London. Why the diagnosis decides the treatment, what makes melasma worse, and realistic timelines.

It depends entirely on which type you have. Sun-induced spots respond well to light-based treatment. Post-inflammatory marks fade with time, topicals and sun protection. Melasma relapses and can be worsened by heat and aggressive laser. Any changing lesion needs medical assessment first.
Conditions this treats
The cost of pigmentation treatment in London depends on what the pigment actually is, because solar damage, post-inflammatory marks and melasma are managed differently. Price is driven by the assessment, the topical regime, whether device sessions are appropriate at all, and the ongoing maintenance the condition needs.
Cost follows the assessment rather than preceding it. What treatment costs sets out how a written quotation should be built, and the guide to choosing a skin clinic covers what an unusually low figure has normally had removed from it.
Pigmentation treatment manages a tendency rather than removing a fault. Solar lentigines cleared by a device may not return for years if sun protection is worn daily. Post-inflammatory marks fade over months. Melasma is chronic and relapsing, so it is controlled in cycles and returns when protection lapses.
Expect improvement rather than erasure, and expect it slowly. A plan that promises clear skin in six weeks is describing something that does not exist.
Pigmentation treatment carries a specific irony: the treatments used can themselves cause pigment change, particularly in deeper skin tones. Heat, light and aggressive exfoliation can all worsen melasma. Safe practice means a recorded skin type, a test patch before any device, conservative settings and daily broad-spectrum sun protection.
Expect the first appointment to be diagnostic rather than procedural. Solar lentigines, post-inflammatory hyperpigmentation, melasma and freckling look similar and behave differently. Expect standardised photographs, a topical regime started first, and a plan measured in months. Any new or changing lesion is referred to a doctor before anything else.
The treatments for these overlap only partially, and one of them can be made permanently worse by a treatment that works well for another. That is why the diagnosis is the whole job.
This is the foundation for every type. Agents that inhibit pigment production, agents that accelerate cell turnover, and antioxidants that reduce the stimulus all have a role, and some of the most effective are available only on prescription. A practitioner who can prescribe has more options than one who cannot, and this is one of the areas where that matters most.
Useful across several types, with agent and depth chosen against skin type. Mandelic acid is often preferred in darker skin. See chemical peels.
Intense pulsed light and pigment-specific lasers work well for solar lentigines in lighter skin. In darker skin the calculation changes, in melasma it changes again, and a test patch is essential in every case. See laser resurfacing.
Used as a delivery route and as a remodelling treatment, with more caution in melasma than the marketing usually implies.
Post-inflammatory marks fade. Treating them aggressively out of impatience is a common way to create more of them.
Choosing a practitioner for pigmentation treatment in London means finding someone who diagnoses before they treat. Ask how they distinguish melasma from sun damage, whether they record skin type and test patch, what topical regime they start with, and under what circumstances they would decline to use a device at all.
Pigmentation treatment with a device is not suitable for anyone with a new, changing, irregular or bleeding lesion, which needs a medical opinion first. It is used cautiously or not at all in melasma, avoided on tanned skin, postponed in pregnancy, and reconsidered where daily sun protection will not be worn.
Pigmented lesions are not all cosmetic. A new mark, a mark that is changing in size, shape or colour, a mark with an irregular border or more than one colour, a mark that itches, bleeds or does not heal, and any mark that looks different from your others all need assessment by a doctor before anybody treats them.
Lasering an undiagnosed pigmented lesion removes the visible sign of something that may need diagnosis, without removing the thing itself. It is the single most serious avoidable error in this area. A responsible clinic will examine your skin properly and will refuse to treat anything it is not certain about, referring you instead.
Any clinic willing to laser a mole without a diagnosis has told you everything you need to know about it.
Melasma behaves less like a stain and more like a condition. The pigment-producing cells in affected areas appear to be persistently overactive rather than simply having produced too much pigment once. That has three consequences.
A sensible melasma plan is topical-led, patient, and built around avoidance: broad-spectrum protection including protection against visible light, avoiding heat where practical, and long-term topical management. Procedural treatment, where it is used at all, is cautious and sits on top of that foundation rather than replacing it.
Ultraviolet A passes through cloud and window glass. Visible light, including from screens and from bright indoor lighting, also contributes to melasma in darker skin types, which is why tinted sunscreens containing iron oxides are often specifically recommended. Ask about this rather than assuming any sunscreen will do.
The same order every time, with the decision made at assessment rather than at the point of sale.
The skin is examined in consistent light and the finding is named before pigmentation and melasma is discussed as an answer to it. Skin type, medical history, medicines and the routine you are already using all change the plan.
For energy-based treatment, particularly in higher Fitzpatrick types, a test patch and a wait rather than a full treatment on a first visit.
The finding, the treatment, the number of sessions, the interval between them, what you use at home and what it costs, in writing.
Conservative settings first, escalated across a course on the basis of how your skin actually responded rather than on a fixed protocol.
Written aftercare covering sun protection, what to apply, what to stop and the signs that mean you telephone rather than wait.
Where the finding will not respond to this treatment, that is said plainly and the correct route is discussed instead of a compromise.
Melasma is usually symmetrical and blotchy across the cheeks, forehead and upper lip and fluctuates with sun and hormones. Sun spots are discrete patches with defined borders on chronically exposed skin. A practitioner should tell you which you have before proposing anything.
It can be improved and controlled. It relapses, so it is managed long term rather than cured.
For solar lentigines in lighter skin, often yes. In melasma, aggressive laser can make things considerably worse. The diagnosis decides the answer.
Months, sometimes longer in darker skin. They do fade. Sun protection and topical treatment speed it up; picking and aggressive treatment slow it down.
Yes. Ultraviolet A passes through cloud and glass all year, and visible light also contributes in darker skin types.
Several effective topical agents are avoided in pregnancy. Melasma often improves after pregnancy. Discuss timing with a clinician rather than starting treatment.
Not without medical diagnosis first. Removing the appearance of a lesion without knowing what it is is a serious error.
