By Megan Bao, 1 June 2026

Quick Answer: What Is Hyperpigmentation?

Hyperpigmentation is a common skin condition that causes patches of skin to appear darker than the surrounding area. It occurs when the skin produces excess melanin, the pigment responsible for skin colour.

Hyperpigmentation can appear as:

While harmless, hyperpigmentation can affect confidence and often becomes more noticeable with age, sun exposure, hormonal changes, acne, or skin trauma.

The good news is that modern treatments such as laser therapy, chemical peels, Microneedling (enquiry) and medical-grade skincare can significantly improve pigmentation and restore a more even complexion.

What Causes Hyperpigmentation?

Hyperpigmentation develops when melanocytes (pigment-producing cells) become overactive and produce excess melanin.

Common causes include:

Ultraviolet (UV) radiation is one of the leading causes of pigmentation.

When exposed to sunlight, the skin increases melanin production as a protective mechanism. Over time, this can lead to:

Even brief daily exposure without SPF can worsen existing pigmentation.

Hormonal fluctuations can trigger melasma, a form of pigmentation that commonly appears on:

Melasma is often associated with:

After acne, eczema, burns, rashes, or skin injuries heal, they can leave behind dark marks known as Post-Inflammatory Hyperpigmentation (PIH).

PIH is particularly common in darker skin tones.

As skin ages, years of cumulative sun exposure often become visible in the form of:

Some medications can increase photosensitivity and contribute to pigmentation, including:

Types of Hyperpigmentation

Understanding the type of pigmentation is crucial because different conditions require different treatments.

Melasma presents as larger patches of brown or grey-brown pigmentation.

Common areas include:

Melasma is often hormonally driven and can be challenging to treat without a personalised approach.

Sun spots are small, flat dark spots caused by years of UV exposure.

They commonly appear on:

These often respond very well to laser treatments.

PIH develops after inflammation or injury to the skin.

Common triggers include:

Freckles are small pigmented spots that often become darker with sun exposure.

While genetic, they can be reduced with certain laser treatments.

Can Hyperpigmentation Go Away Naturally?

Some forms of pigmentation may fade naturally over several months.

However, deeper pigmentation such as melasma or long-standing sun damage often requires professional treatment.

Without treatment, pigmentation may:

Early intervention usually delivers the best outcomes.

The Best Treatments for Hyperpigmentation

The most effective treatment depends on:

A professional consultation is essential to determine the safest and most effective approach.

Laser Treatment for Hyperpigmentation

Laser treatment is one of the most advanced solutions for pigmentation removal.

Specialist lasers target excess melanin while minimising damage to surrounding skin.

Benefits include:

At London Premier Laser, several technologies may be used depending on the type and depth of pigmentation.

PicoSure Pro uses ultra-short pulses of laser energy to shatter pigment particles into tiny fragments that are naturally cleared by the body.

It is particularly effective for:

Harmony ClearLift provides gentle laser rejuvenation with minimal downtime.

It can help improve:

It is often suitable for patients seeking a more gradual approach.
