Pigmentation and sun damage in Gibraltar
Brown patches on the cheeks, freckling across the nose and forehead, marks left behind by spots. Gibraltar sits at thirty-six degrees north and gets sun for most of the year, which is why pigmentation is the most common skin complaint we are asked about. This page explains what it is and what actually works on it.

The Latitude
The same skin, kept in Manchester, would look ten years younger. That is not a compliment to Manchester.
Where you live is part of the diagnosis.
Pigmentation is a dose problem. It accumulates from the total amount of ultraviolet light your skin has taken, over decades, and Gibraltar delivers a larger dose than almost anywhere people move here from.
Thirty-six degrees north. The sun is high, the ultraviolet index runs high from March through to October, and it is not zero in January. Latitude is the single biggest thing separating skin here from skin in northern Europe.
Life here happens outdoors. Walking to work, lunch on a terrace, a beach that is fifteen minutes away, and a marina that is always in full sun. Nobody plans that exposure, which is exactly why it adds up unrecorded.
The frontier commute counts. A car window blocks most of the burning wavelengths and very little of the ageing ones. Driving between two sunny places, five days a week, for years, shows on the side of the face nearest the window.
Heat is part of it too. Melasma in particular responds to warmth and to visible light, not only to ultraviolet. A shaded terrace in August is not the safe option people assume it is.
What It Actually Is
Pigment is a defence. It appears because the skin is protecting itself, which is why it is so reluctant to leave.
A pigment cell doing its job too well, in the wrong place.
Melanocytes make the pigment.
Scattered through the base of the skin are cells called melanocytes. They manufacture melanin and hand it to the surrounding skin cells, which carry it like an umbrella over the nucleus. Everybody has roughly the same number of these cells. What differs is how much they produce.
Three things switch them on.
Ultraviolet light is the obvious one. Hormones are the second, which is why pregnancy and the contraceptive pill can start it. Inflammation is the third: any spot, scratch, burn or reaction can leave pigment behind after it has healed.
Once switched on, they stay sensitive.
A patch of skin that has made too much pigment once will do it again faster and with less provocation. That is the honest reason pigmentation is managed rather than cured, and why a treatment without daily protection afterwards is money spent twice.
The Three Kinds
Three different problems that all look brown.
They are treated differently and they behave differently. Getting the name right before anything is booked matters more here than in almost any other skin complaint.
Sun spots, or lentigines. Flat, well-defined, tan to dark brown, on the face, the backs of the hands, the chest and the shoulders. They are a direct record of ultraviolet exposure, they arrive from the thirties onwards, and they are the most straightforward of the three to improve.
Melasma. Larger, softer-edged patches, usually symmetrical, across the cheeks, the upper lip, the forehead and the jaw. It is hormonal, it affects women far more than men, and it is stubborn. Heat and visible light provoke it as much as ultraviolet does, so it flares every summer and often after a hot kitchen or a long drive.
Post-inflammatory pigmentation. The flat brown mark a spot, a scratch, a wax burn or a reaction leaves behind. It is not a scar and it does fade on its own, though it can take six to twelve months. Picking at the original spot is the single biggest thing that makes it worse and last longer.
Melasma returns because the melanocytes that caused it are still there and still sensitive. Any treatment that promises to end it permanently is describing a condition it has not understood.
The Options
The first column is the one that works. The others are how quickly you would like the existing marks dealt with.
Four routes, and the cheapest one is the most effective.
| Daily sun protection | Medical-grade skincare | In-clinic treatment | Doing nothing | |
|---|---|---|---|---|
| What it actually changes | Stops new pigment forming and keeps existing marks from darkening | Slows the cells that make pigment and speeds up how fast the skin sheds it | Breaks up pigment that is already sitting in the skin | Nothing. New marks keep arriving and old ones deepen |
| How long it takes | It is working from the first morning you use it | Twelve weeks before it can be judged fairly | A course of sessions, spaced two to four weeks apart | No time at all |
| How long it lasts | For as long as you keep using it | For as long as you keep using it | Until the first unprotected summer undoes it | Cumulative, in the wrong direction |
| What it costs you in time | Two minutes a morning, ongoing, forever | A few minutes morning and night | A course of appointments, then maintenance | Nothing |
| How it does on melasma | Well — it is the main treatment, not the background one | Slowly, and it needs patience | Sometimes, and heat-based treatment can provoke it | It carries on flaring each summer |
| The honest downside | It is dull, and nobody wants it to be the answer | It can irritate at first, and results are gradual | It will not hold without the first column beside it | Sun damage is not only a cosmetic matter |
In-clinic work clears what is already there. Protection and skincare decide whether it stays cleared. Treating without the other two is the most common reason people tell us pigmentation treatment did not work for them.
The Actual Treatment
Not the boring option. The effective one, which happens to be dull.
Sunscreen is the treatment. Everything else is tidying up after it.
If you did one thing on this page and ignored the rest, do this one. It outperforms every treatment we sell, and we would rather say so than have you buy a course that unwinds by September.
SPF 50 on the face and neck, every morning, all year. Not only on beach days. The exposure that causes pigmentation here is the walk to work, the terrace at lunch and the school run, none of which anybody counts.
Use about two fingers’ length for a face and neck. Most people apply roughly a quarter of the amount a sunscreen is tested with, which quietly turns SPF 50 into something far lower. The quantity matters as much as the number on the bottle.
Reapply every two hours if you are actually out in it. Reapplication is the step people skip, not the first application. A powder or a stick over make-up is easier to keep up than a second layer of cream, and something you keep up beats something you do not.
For melasma, choose a tinted one with iron oxides. Melasma is provoked by visible light as well as ultraviolet, and clear sunscreens do very little about visible light. Iron oxides are what makes a tinted formula work here. This is the single most useful sentence on the page for anyone with melasma.
A hat and the shaded side of the street cost nothing. They never wash off, never need reapplying and never run out. In a Gibraltar August they do more than most products manage.
When To See A Doctor
A cosmetic treatment on a mark that needed a biopsy does two kinds of harm: it removes the evidence and it buys time nobody had.
Some marks are not a cosmetic problem, and we will decline to treat them.
This is the one part of the page that is not about appearance. A country with this much sun has more skin cancer than a country without, and the same brown mark can be either harmless or not.
Anything that is changing. A mole or mark that has altered in shape, colour or size over weeks or months. Change is the signal, more than how it looks on any single day.
Anything that bleeds, itches, crusts or will not heal. A spot or sore on sun-exposed skin that keeps scabbing and returning over more than a month should be examined, not covered up.
Anything that looks unlike the rest. If one mark stands out from all your others in colour, outline or size, that is worth showing to someone. Uneven edges and more than one colour within a single mark are both worth mentioning.
Take it to a GP or a dermatologist, not to us. We do not diagnose skin lesions and we will not treat a mole or a mark of this kind at any price. If we see one at a consultation we will tell you and ask you to have it checked before we do anything else.

Questions
Pigmentation, answered.
Is melasma the same thing as sun spots?
No. Sun spots are small, sharply defined and caused directly by ultraviolet exposure over years. Melasma is a larger, soft-edged, usually symmetrical patch driven by hormones and made worse by light and heat. They respond to different treatment, which is why naming it correctly comes first.
Why does my melasma come back every summer?
Because the pigment cells that produce it are still in place and still sensitive. Treatment clears what they have already made. Sun, heat and visible light switch them back on. In Gibraltar that combination arrives every year, which is why melasma is managed rather than finished.
Do I really need sunscreen in a Gibraltar winter?
Yes, though less urgently than in July. Ultraviolet does not stop in December at this latitude, and the wavelengths that drive pigmentation and ageing pass through cloud and glass. Once pigmentation has started, a winter without protection is enough to hold it in place.
Can driving cause pigmentation?
It contributes. A windscreen filters most of the burning wavelengths, but a side window lets a good deal of the ageing ones through. People who cross the frontier daily often show more pigmentation and more lines on the side of the face nearest the window.
Will a carbon peel clear my pigmentation?
It helps with surface pigment, dullness and congestion, and it suits sun spots better than melasma. It is a course, not a single session, and it holds only if daily protection comes with it. We will tell you at the consultation if your pigment is the wrong kind for it.
How long does the mark from a spot take to fade?
Anywhere from three to twelve months on its own. Sun exposure on the healing mark is what stretches that out, and so is picking at the original spot. Sunscreen over the mark, every day, does more to shorten it than any product sold for the purpose.
Can pigmentation be removed permanently?
Individual sun spots can be cleared and often stay clear. Melasma cannot be finished, only kept quiet, because the cause is still there. Anyone promising permanent removal of melasma is describing a condition they have not understood, and it is worth walking away from that.
I have a mole I would like treated. Can you do it?
No. We do not diagnose or treat moles and skin lesions, and we will not lase over one. Please see a GP or a dermatologist first. If it turns out to be harmless and you still want the surrounding pigmentation improved, come back to us then.
