If you've ever searched online for answers about dark spots, you've probably come across terms like hyperpigmentation, melasma, sun spots, age spots and post-inflammatory hyperpigmentation (PIH).

Many people use these terms interchangeably, but they're not the same thing.

Understanding which type of pigmentation you have is one of the most important steps towards choosing an effective skincare routine. Different types of pigmentation develop for different reasons, respond differently to treatment and often require different long-term management strategies.

At FWBEAUTY, our formulations are developed around the science of pigmentation, helping to support brighter, more even-looking skin while respecting the skin barrier.

In this guide, we'll explain the differences between the most common forms of pigmentation and help you recognise what may be affecting your skin.

What is hyperpigmentation?

Hyperpigmentation is an umbrella term.

It simply means an area of skin has become darker than the surrounding skin because excess melanin has been produced.

Melanin is the natural pigment responsible for the colour of your skin, hair and eyes.

Hyperpigmentation itself is not a diagnosis.

Instead, it describes the appearance of excess pigmentation, which may be caused by several different conditions, including:

• Melasma
• Post-inflammatory hyperpigmentation (PIH)
• Sun spots
• Freckles
• Certain medications
• Skin injury
• Hormonal changes

Think of hyperpigmentation as the category, while melasma and sun spots are specific types within that category.

Understanding melanin

Before comparing the different conditions, it's useful to understand how pigmentation develops.

Specialised cells called melanocytes produce melanin whenever the skin needs protection.

Melanin production increases in response to:

• Ultraviolet (UV) radiation
• Inflammation
• Hormonal changes
• Skin injury

When too much melanin is produced or distributed unevenly, visible pigmentation develops.

Although the trigger differs, the biological process is remarkably similar across many pigmentation disorders.

What is melasma?

Melasma is a chronic pigmentation condition primarily influenced by hormones and sunlight.

It typically appears as larger patches of brown or grey-brown pigmentation rather than individual spots.

Unlike other forms of pigmentation, melasma often affects both sides of the face symmetrically.

Common locations

• Cheeks
• Forehead
• Bridge of the nose
• Upper lip
• Chin

Common triggers

• Pregnancy
• Oral contraceptives
• Hormonal fluctuations
• Sun exposure
• Heat
• Visible light

Melasma is sometimes referred to as the "mask of pregnancy" because it commonly develops during pregnancy.

However, it can also affect men and women who have never been pregnant.

What is Post-Inflammatory Hyperpigmentation (PIH)?

Post-inflammatory hyperpigmentation develops after the skin experiences inflammation or injury.

Unlike melasma, PIH appears exactly where the skin was previously damaged.

Common causes include:

• Acne
• Eczema
• Psoriasis
• Cosmetic treatments
• Burns
• Cuts
• Insect bites
• Picking blemishes

Once inflammation settles, excess melanin remains behind, creating flat brown or grey marks.

PIH is particularly common in medium to deeper skin tones because melanocytes are generally more reactive.

What are sun spots?

Sun spots, also called solar lentigines or age spots, develop after years of cumulative ultraviolet exposure.

Unlike freckles, sun spots usually remain visible all year round.

They often appear later in life because they result from repeated sun damage accumulated over many years.

Common locations

• Face
• Hands
• Chest
• Shoulders
• Arms

Sun spots are one of the clearest signs of long-term photoageing.

Melasma vs PIH vs Sun Spots

How to tell which type you have

Ask yourself these questions:

Did the pigmentation appear after acne?

If yes, it's likely post-inflammatory hyperpigmentation.

---

Did it develop during pregnancy or hormonal changes?

This strongly suggests melasma.

---

Has it appeared gradually over many years?

Well-defined spots on sun-exposed areas often indicate sun spots.

---

Is it symmetrical?

Melasma frequently appears almost identically on both sides of the face.

PIH usually does not.

Can you have more than one type?

Yes.

Many people have a combination of pigmentation conditions.

For example:

• Melasma with acne-related PIH
• Sun spots alongside melasma
• PIH combined with age spots

This is why a personalised skincare routine is often more effective than treating pigmentation as a single condition.

Why sunscreen matters for every type

Regardless of the cause, ultraviolet radiation stimulates melanocytes.

Without daily sun protection:

• Existing pigmentation may darken.
• New pigmentation may develop.
• Brightening treatments become less effective.
• Results may take longer to achieve.

A broad-spectrum sunscreen with SPF 30 or higher should be part of every pigmentation routine.

Ingredients commonly used for pigmentation

Although different types of pigmentation have different triggers, many skincare ingredients support a brighter, more even-looking complexion.

Commonly used ingredients include:

Niacinamide

Helps strengthen the skin barrier while reducing the transfer of melanin between skin cells.

Tranexamic Acid

Widely used in modern pigmentation formulations to improve the appearance of stubborn discolouration.

Vitamin C Derivatives

Provide antioxidant protection while helping brighten uneven skin tone.

Liquorice Root Extract

Contains naturally occurring compounds known for their skin-brightening properties.

Bakuchiol

A plant-derived ingredient that supports smoother, healthier-looking skin with excellent tolerability.

Peptides

Help support overall skin quality and complement brightening routines.

Saffron Extract

Rich in naturally occurring antioxidants that help promote a brighter-looking complexion while supporting healthy skin.

The importance of protecting your skin barrier

Many people assume stronger products mean faster results.

In reality, irritation often increases inflammation.

Inflammation can stimulate melanocytes, leading to more pigmentation.

Maintaining a healthy skin barrier helps reduce unnecessary irritation while supporting consistent long-term improvement.

Gentle, consistent skincare almost always outperforms aggressive routines.

How FWBEAUTY approaches pigmentation

At FWBEAUTY, we recognise that pigmentation is influenced by multiple biological pathways, including melanin production, inflammation, oxidative stress and skin barrier function.

Surface Reset Enzyme Powder Cleanser

A gentle enzyme cleanser that refines skin texture while respecting the skin barrier, helping prepare the skin for the rest of your routine.

Frequently Asked Questions

Is melasma the same as hyperpigmentation?

No. Hyperpigmentation is a general term for excess skin pigmentation. Melasma is one specific type of hyperpigmentation caused primarily by hormonal influences and sun exposure.

---

Are sun spots permanent?

Sun spots may persist for many years without treatment. Daily sun protection can help prevent new ones from developing and stop existing spots from becoming darker.

---

Can acne cause melasma?

No. Acne causes post-inflammatory hyperpigmentation rather than melasma.

---

Which type of pigmentation is hardest to treat?

Melasma is often considered the most challenging because hormonal influences, UV radiation and visible light can all contribute to recurrence.

---

Can I have melasma and PIH at the same time?

Yes. Many people experience more than one type of pigmentation, particularly if they have both hormonal pigmentation and acne.

---

Although all forms of pigmentation involve excess melanin, the underlying cause makes a significant difference to how each condition behaves.

Melasma is driven largely by hormones and sun exposure, PIH develops after inflammation, and sun spots are the result of years of cumulative UV damage.

Recognising which type of pigmentation you have allows you to build a more effective skincare routine and set realistic expectations for improvement.

With consistent daily sun protection, barrier-supporting skincare and targeted brightening ingredients, many forms of pigmentation can become noticeably less visible over time, helping restore a brighter and more even-looking complexion.
