Not all pigmentation is melasma and knowing the difference is the first step towards getting the right treatment.
Uneven skin tone, brown spots and darker patches are some of the most common skin concerns we see in the treatment room. But while the words pigmentation and melasma are often used interchangeably, they are not actually the same thing.
Pigmentation is a broad term used to describe areas of skin that have become darker than the surrounding skin. Melasma, on the other hand, is a specific and often more complex pigmentary condition.
Understanding what is causing the pigmentation is essential because the wrong treatment – particularly overly aggressive exfoliation, peels or energy-based treatments — can sometimes make pigmentation worse.
What is pigmentation?
Hyperpigmentation occurs when the skin produces more melanin, the pigment responsible for our skin colour.
There are many different reasons this can happen, including:
- Sun exposure and cumulative UV damage
- Hormonal changes
- Acne and inflammation
- Skin injuries or trauma
- Irritation from skincare products
- Certain medications
- Ageing
- Post-inflammatory hyperpigmentation following treatments or skin conditions
One of the most common forms is post-inflammatory hyperpigmentation (PIH). This is the dark mark that can remain after acne, an insect bite, a wound, inflammation or even an overly aggressive treatment.
Pigmentation can appear as individual brown spots, scattered marks or larger areas of uneven colour.
The good news is that many forms of pigmentation respond very well when the underlying trigger is identified and controlled. However, deeper pigment can take considerably longer to fade.
So, what exactly is melasma?
Melasma is a chronic pigmentary disorder characterised by larger, symmetrical patches of pigmentation, most commonly appearing on the:
- Cheeks
- Forehead
- Upper lip
- Nose
- Chin
- Jawline
It can also occur on the neck and other areas.
Melasma typically appears as brown, grey-brown or, in some skin tones, blue-grey patches. It is often symmetrical – for example, pigmentation appearing on both cheeks.
Unlike a single sun spot, melasma is not simply a collection of pigment sitting on the surface of the skin. It involves increased activity of melanocytes and can involve several biological pathways, including hormonal, vascular and inflammatory influences.
Sunlight and visible light can stimulate melasma, while hormonal influences, pregnancy, oral contraceptives, heat and other triggers may also contribute.
Why is melasma so difficult to treat?
This is where the difference between ordinary pigmentation and melasma becomes particularly important.
Melasma can be persistent and recurrent. Even when the pigmentation has improved significantly, the tendency to develop it remains.
This means that treating melasma is not simply about “removing the pigment”. The objective is to:
Suppress excess melanin production → reduce existing pigmentation → protect the skin → prevent recurrence.
For this reason, melasma is best approached as a long-term skin-management programme rather than a single treatment.
Pigmentation vs melasma: how can you tell the difference?
| Pigmentation | Melasma |
| Broad term covering many types of darkening | Specific pigmentary condition |
| Can occur anywhere on the body | Usually occurs on the face |
| Often individual spots or irregular marks | Usually larger, symmetrical patches |
| Commonly caused by sun damage, acne or inflammation | Often influenced by hormones, sunlight, visible light and other triggers |
| Can sometimes respond relatively quickly | Often requires long-term management |
| Treating the cause can prevent recurrence | Has a tendency to return |
| Procedures may be appropriate depending on the type | Procedures need much greater caution |
However, appearance alone is not always enough to make a diagnosis.
Melasma can resemble post-inflammatory pigmentation, solar lentigines and other pigmentary conditions. A professional skin assessment is therefore important before deciding on a treatment programme.
The most important treatment of all: SPF
If you are treating pigmentation but not protecting the skin from UV and visible light, you are fighting an uphill battle.
Daily broad-spectrum SPF 50+ should be considered an essential part of any pigmentation programme.
For melasma in particular, protection against visible light is also important. Tinted sunscreens containing iron oxides can provide additional protection against visible light, which has been shown to aggravate melasma, particularly in darker skin tones.
And sunscreen isn’t just for sunny days.
UV exposure occurs throughout the year, so pigmentation-prone skin needs protection every day.
We also recommend:
- Reapplying sunscreen throughout the day when exposed to sunlight
- Wearing a hat when outdoors
- Seeking shade where possible
- Avoiding tanning beds and intentional tanning
- Managing heat exposure where it is a known trigger
- Being consistent rather than relying on occasional high-SPF application
What ingredients can help pigmentation?
A successful pigmentation programme usually combines several mechanisms rather than relying on one “miracle” ingredient.
1. Vitamin C
Vitamin C is an antioxidant that can help protect the skin against oxidative stress while supporting a brighter, more even complexion.
2. Niacinamide
Niacinamide can help reduce the appearance of pigmentation while also supporting the skin barrier, making it particularly useful in a carefully balanced pigmentation routine.
3. Tranexamic acid
Tranexamic acid has become an increasingly important ingredient in pigmentation management and is used in a number of professional skincare formulations. It is particularly interesting for stubborn pigmentation and melasma.
4. Kojic acid
Kojic acid works by inhibiting tyrosinase, an enzyme involved in melanin production, and can be incorporated into pigmentation-focused routines.
5. Alpha-arbutin and other tyrosinase inhibitors
These ingredients can help regulate melanin production and are useful for gradually reducing uneven pigmentation.
6. Retinoids and vitamin A
Vitamin A can support cell turnover and improve the appearance of uneven skin tone. It can be valuable as part of a comprehensive programme, although it should be introduced appropriately to avoid unnecessary irritation.
7. Cysteamine
Cysteamine is a particularly interesting ingredient for stubborn pigmentation and melasma. Cysteamine cream has clinical evidence supporting its use in epidermal melasma and hyperpigmentation.
Professional treatments for pigmentation
Professional treatments can accelerate improvement, but the treatment needs to match the type and depth of pigmentation.
Depending on the individual, options may include:
1. Chemical peels
Superficial chemical peels can help improve epidermal pigmentation and encourage skin renewal.
Ingredients such as glycolic, lactic, mandelic, salicylic and phytic acids may be incorporated into pigmentation protocols.
However, more aggressive is not necessarily better.
Inflammation can stimulate melanocyte activity and potentially lead to post-inflammatory hyperpigmentation — particularly in darker skin tones.
2. Microneedling
Microneedling may be used as part of a pigmentation programme in selected clients and can sometimes improve the penetration of topical products.
However, melasma requires particular caution because any procedure that creates inflammation has the potential to aggravate pigmentation.
3. IPL and laser treatments
Certain pigmentation concerns can respond well to IPL or laser treatments, particularly selected superficial sun-related pigmentation.
Melasma is different.
IPL and laser treatments can cause relapse or worsening of melasma in some individuals, so they should not be considered the automatic first choice for every client with facial pigmentation.
A careful consultation, skin assessment and appropriate preparation are essential.
Our professional approach to pigmentation
At our clinic, we believe pigmentation should never be treated with a “one treatment fits all” approach.
We look at:
- What type of pigmentation is present?
- What caused it?
- How deep is the pigment?
- Is the skin inflamed or compromised?
- Is there an underlying hormonal component?
- What is the client’s Fitzpatrick skin type?
- What skincare is currently being used?
- Has the client previously had peels, IPL or laser treatments?
Only once these factors have been considered can we create an appropriate treatment and homecare programme.
The perfect pigmentation routine doesn’t have to be complicated
One of the biggest mistakes we see is clients using too many active ingredients at once.
They become frustrated by the pigmentation, add another acid, another serum, another exfoliant — and eventually compromise their skin barrier.
Inflamed skin can become more pigmented.
Instead, think about pigmentation in four stages:
1. Protect
- SPF 50+ every day.
For melasma, consider a tinted sunscreen containing iron oxides to provide additional visible-light protection.
2. Calm
A healthy skin barrier is essential.
Avoid excessive exfoliation and products that cause persistent burning, stinging or irritation.
3. Correct
Introduce appropriate pigment-targeting ingredients such as tranexamic acid, cysteamine, vitamin C, niacinamide, kojic acid, arbutin or retinoids — depending on the individual skin and diagnosis.
4. Maintain
Pigmentation is not simply something we “clear” and forget about.
Once improvement has been achieved, maintenance skincare and daily sun protection are what help keep the results.
We stock several advanced pigmentation ranges because different types of pigmentation and different skin types require different approaches.
How long does pigmentation take to improve?
This is one of the most important conversations to have with a client.
Pigmentation doesn’t usually appear overnight, and it shouldn’t be expected to disappear overnight either.
Some superficial pigmentation can improve within several weeks, while more established pigmentation may take several months.
Melasma can take 3–12 months or longer to achieve significant improvement, and ongoing maintenance is often necessary because recurrence is common.
The goal should therefore not simply be:
“How quickly can we remove the pigment?”
It should be:
“How can we safely reduce the pigment, prevent new pigment from forming and keep the skin healthy?”
The bottom line:
Pigmentation and melasma may look similar, but they are not necessarily the same condition — and treating them successfully requires understanding why the pigmentation is there in the first place.
The most effective approach is rarely a single product or treatment.
It is a combination of:
Professional assessment + appropriate in-clinic treatments + targeted homecare + excellent sun and visible-light protection + consistency.
And perhaps most importantly, pigmentation requires patience.
If you’re struggling with stubborn pigmentation or aren’t sure whether you have pigmentation, post-inflammatory hyperpigmentation or melasma, a professional skin consultation can help determine the most appropriate approach for your skin.
Your skin is individual, your pigmentation treatment should be too.
