Condition
What the finding is, how it is assessed, which treatments address it in Glasgow, what will not work, how long results take and what moves the cost.

Because sun-induced lentigines, post-inflammatory pigmentation, melasma and freckling look similar and behave completely differently. Lentigines respond well to resurfacing. Melasma frequently worsens after heat or aggressive treatment and needs a cautious, medical and long term approach. Treating the wrong one makes the appearance worse, sometimes permanently.
Treatments that address this
Pigment is produced by melanocytes at the base of the epidermis and transferred to the keratinocytes above them. Almost everything that makes skin darker in a patch does so by stimulating that process. What differs is the trigger, the depth at which the pigment ends up, and how the skin behaves when you interfere with it.
Occasionally a pigmented lesion is none of these and needs a medical opinion rather than a cosmetic one. Any new, changing, irregular or bleeding pigmented lesion is a reason to see a doctor rather than to book a treatment.
The assessment is diagnostic before it is cosmetic. It establishes which pattern is present, how deep the pigment sits, what is driving it, and how the skin is likely to behave if it is treated.
Topical medical therapy sits behind most successful outcomes in melasma and is prescribed and supervised rather than bought over a counter. That is a reason to see a doctor about melasma, not a reason to avoid the subject.
Heat is the recurring problem. Melasma responds to heat as well as to light, which means that devices delivering thermal energy can clear a patch briefly and then produce a rebound that is darker than the starting point. This is well described and it is the reason a cautious clinic will decline to treat melasma with an aggressive device even when asked.
Aggressive peeling in deeper skin tones carries the same risk by a different mechanism. The inflammation caused by the treatment provokes exactly the pigment response you were trying to remove.
Ask what happens if the pigment comes back darker. A clinic with a considered answer, a plan and a topical protocol has treated pigmentation before. A clinic that says it will not happen has not.
Skin lightening products bought online are a genuine hazard. Unregulated preparations containing high strength hydroquinone, mercury or potent steroids remain in circulation and cause lasting damage. If a product has no ingredient list, no manufacturer and no regulatory route, it does not belong on a face.
Nothing on this page is fast. Superficial peel courses are assessed over months, not weeks, and improvement is gradual and partial.
Melasma in particular is managed rather than cured. Periods of clearance are realistic; permanent clearance generally is not, because the tendency remains and the triggers are part of ordinary life. Sensible expectations here are the difference between a patient who is satisfied and one who spends years and a great deal of money chasing a finish line that does not exist.
Solar lentigines behave better. They can clear substantially with appropriate treatment and then stay clear provided sun exposure is controlled. New ones appear if it is not.
This is a course-based condition and a long term one, so the useful question is not what a session costs but what a year of appropriate management costs.
What drives the price of treatment covers the general principles.
The single most useful screening question is what the practitioner will not treat. Someone who will treat any pigmentation with the same device has not understood the problem.
Ask which pattern they believe you have and why. Ask what your Fitzpatrick type is and how it changed the plan. Ask what the protocol is if pigment rebounds. Ask whether they are prepared to refer you for a medical opinion, and note that a good answer here involves the word yes.
The standards to expect from a clinic in Glasgow covers registration and verification, and the consultation sets out what a thorough assessment covers.
Common questions
It is managed rather than cured. Periods of substantial clearance are achievable with sun protection, appropriate topical therapy and cautious procedural treatment, and the tendency remains. Anyone offering a permanent cure has either misdiagnosed the pattern or is overstating what the evidence supports.
It depends entirely on which pattern is present and on skin type. Discrete sun-induced spots in lighter skin can respond very well. Melasma frequently rebounds after heat-based treatment, and deeper skin tones carry a higher risk of post-inflammatory pigmentation. This is the clearest example on the site of a treatment that is excellent in one case and harmful in another.
Months. Superficial peel courses are assessed over a course rather than after a session, and post-inflammatory marks fade over six to twelve months whether or not they are treated. Improvement is gradual, and the pace is set by the biology rather than by the number of appointments booked.
It is the intervention that changes every other outcome on this page. Visible light as well as ultraviolet drives melasma, which is why a tinted preparation containing iron oxides is often recommended over a clear one. Treatment without daily protection is money spent on a result that will not hold.
For melasma, yes, at least once, because the topical therapies with the best evidence are prescribed and supervised. For any new, changing, irregular or bleeding pigmented lesion, urgently and without exception. Aesthetic treatment sits alongside medical care here rather than instead of it.
