Hyperpigmentation: Skincare to Clinic Treatment Options

Hyperpigmentation is one of the most common skin concerns people seek help for, and understanding what it actually is can make treatment options much easier to navigate.

What causes patches of darker skin?

Hyperpigmentation happens when certain areas of skin produce more melanin than usual, the pigment responsible for skin colour. This can happen for several reasons:

• Sun exposure, which stimulates melanin production as a protective response
• Hormonal changes, particularly those linked to pregnancy, contraception, or hormone therapy
• Inflammation or injury, including acne, eczema, cuts, or cosmetic procedures
• Certain medications, which can trigger pigment changes as a side effect
• Genetic and skin type factors, which influence how reactive your skin is to the triggers above

In practice, most people experience a combination of these factors rather than just one. Someone with acne-prone skin who also spends a lot of time outdoors, for example, may notice pigmentation building from both inflammation and sun exposure at once.

Why some skin types are more affected

Hyperpigmentation is particularly common in people with Fitzpatrick skin types III to VI, which broadly covers olive, brown, and darker skin tones. This is because these skin types tend to have more reactive melanocytes, the cells that produce melanin, making them more likely to respond to inflammation or UV exposure with visible pigment changes.

This does not mean lighter skin types are unaffected. Sun spots and freckles, for instance, are more commonly seen in fairer skin. The difference often comes down to which type of pigmentation is more likely, rather than whether pigmentation happens at all.

Understanding what is driving your pigmentation is often the first step towards choosing a treatment approach that actually fits your skin.

Laser and light-based treatments are often associated with pigmentation removal, but they are not suitable for everyone; skin tone plays a significant role in determining their appropriateness.

What lasers and light treatments can and cannot treat

These treatments work by targeting pigment in the skin with concentrated light, which the body then breaks down and clears over time.

• They tend to work best on pigment that sits closer to the surface of the skin, such as sun spots and some types of post-inflammatory hyperpigmentation
• Melasma is more complicated, as the pigment can sit deeper in the skin, and laser treatment alone does not always provide lasting improvement
• Most people need a course of several sessions rather than a single treatment, and gaps between sessions allow the skin to recover
• Devices vary considerably. Non-ablative fractional lasers, such as LaserMe, work by treating tiny columns of skin while leaving the surrounding tissue intact, which is one approach used for general skin tone and texture concerns

Risks in darker skin tones

This is one of the most important considerations for laser and light-based treatments. In darker skin tones, certain lasers can actually trigger new pigmentation rather than reduce it, sometimes making the original concern more noticeable.

• This happens because the laser can affect melanin in the surrounding skin, not just the targeted pigment
• The risk varies depending on the type of laser or device used, with some technologies considered more suitable for darker skin tones than others
• This is not a reason to avoid treatment altogether, but it does mean the choice of practitioner and equipment matters more for some skin tones than others

If you have a darker skin tone, it is worth asking a practitioner specifically about their experience treating similar skin tones and which device they would recommend, rather than assuming all lasers work the same way.

Sessions, downtime and aftercare

Downtime varies depending on the treatment used, but it is common to experience some redness or sensitivity for a short period afterwards. Sun protection becomes especially important during this time, as treated skin can be more reactive to UV exposure.

Laser and light-based treatments can be effective for the right type of pigmentation and skin tone, but they are not a one-size-fits-all solution, and getting the assessment right at the start matters more than the treatment itself.

Hyperpigmentation does not affect everyone equally, and understanding who is more likely to experience it can help explain why treatment recommendations sometimes vary from person to person.

Skin tone and Fitzpatrick type

As mentioned earlier, people with Fitzpatrick skin types III to VI, which covers olive, brown and darker skin tones, tend to experience hyperpigmentation more often and find it more persistent once it develops.

• This is partly because melanocytes in these skin types tend to respond more readily to inflammation or injury
• It does not mean treatment is unavailable, but it often means treatments need to be chosen and monitored more carefully to avoid triggering further pigmentation
• Patch testing and a more cautious, gradual approach are often recommended for darker skin tones, particularly with peels, lasers and topical retinoids

Hormonal factors

Hormonal changes are a significant factor for many people, particularly women:

• Pregnancy can trigger melasma, sometimes referred to as the "mask of pregnancy", due to hormonal shifts affecting melanin production
• Hormonal contraception and hormone replacement therapy have also been linked to melasma in some people
• Menopause can bring its own changes to skin, including how pigmentation behaves, though this varies considerably between individuals

Acne-prone skin

For people who experience acne, pigmentation can be an additional concern alongside the acne itself:

• Post-inflammatory hyperpigmentation often follows acne lesions, particularly if they are picked or squeezed
• This type of pigmentation can sometimes take longer to fade than the acne itself, which can be frustrating
• Treating the acne and the pigmentation often needs to be considered together, as ongoing breakouts can continue to trigger new pigmentation

Men and pigmentation

While pigmentation concerns are often discussed in relation to women, men experience hyperpigmentation too, commonly linked to sun exposure, acne, or shaving-related irritation. The treatment approach is generally similar, though men may be less likely to have previously used skincare routines that include SPF or active ingredients.

Recognising which of these factors applies to you can help guide a more tailored conversation with a GP, dermatologist or practitioner about the right starting point.

With so many options available, deciding where to start can feel overwhelming, but breaking it down into a few simple questions can make the decision much clearer.

When self-care and over-the-counter options make sense

For many people, particularly those with mild or recently developed pigmentation, starting with accessible options is a reasonable first step:

• Consistent use of SPF, alongside ingredients like vitamin C, niacinamide or lower-strength azelaic acid, can be a sensible starting point
• This approach often suits pigmentation linked to sun exposure or mild post-acne marks, where the pigment is likely to be sitting closer to the skin's surface
• Giving these changes time to work, generally several weeks at a minimum, is important before judging whether they are helping

When to consider seeing a GP

A GP visit may be worth considering if:

• Pigmentation has not improved after a reasonable period of consistent self-care
• You are interested in prescription options, such as higher strength azelaic acid or, in some cases, oral tranexamic acid
• Pigmentation appeared suddenly, is widespread, or you are unsure what type of pigmentation you are dealing with

A GP can also help rule out other skin conditions that may resemble hyperpigmentation but require a different approach.

When specialist or clinic-based treatment may be appropriate

For pigmentation that has not responded to topical treatments, or where professional procedures are being considered, a referral to a dermatologist or a consultation with a qualified aesthetic practitioner may be the next step:

• This is often the route for melasma that has not improved with topical treatment alone
• It is also relevant if you are considering chemical peels, laser treatments such as LaserMe, or microneedling, where a professional assessment of your skin tone and pigmentation type is important
• A practitioner can help determine which treatment, or combination of treatments, is likely to be appropriate for your specific skin

There is no single correct starting point for everyone, and what works well for one person's pigmentation may not be the right fit for another. The most useful first step is often an honest assessment of what you are dealing with, whether that is at home, with a GP, or with a specialist, so that any treatment chosen is appropriate for your skin and your expectations are realistic from the outset.
