Skin Pigmentation Disorders: Type, Treatment and Cause

Discover causes, types, and treatments for various skin pigmentation issues such as melasma, vitiligo, and sun damage, with expert tips on prevention.

What is Skin Pigmentation?

Our melanocytes produce melanin, which gives skin its colour and defines its natural tone. It influences how your skin, irises, and hair appear. Changes in melanin production can result in skin pigmentation disorders, which may cause dark or light patches to appear.

Disorders involving skin pigmentation occur when the body produces either too much or too little melanin. In both cases, uneven pigmentation is the result, visible as blotches, streaks or discoloured patches. Pigmentation issues can appear anywhere on the body and affect small or large areas. In some cases, the condition affects only small areas. In others, large portions of the body may experience a noticeable shift in tone.

Types of Skin Pigmentation Disorders

Skin pigmentation issues are generally divided into two types: hyperpigmentation and hypopigmentation.

Hyperpigmentation

When the skin produces too much melanin, it can develop dark spots or patches — a condition known as hyperpigmentation. It is one of the most common pigmentation concerns and can affect all skin types. Pigmentation often develops on the face, neck, and shoulders after repeated sun exposure.

Skin Conditions

Several skin conditions can cause pigmentation to appear uneven or patchy. The sun, hormones, or inflammation generally trigger them. Each responds best to targeted care.

• Melasma causes brown or grey blotches, usually on the cheeks, forehead, or upper lip. Hormonal changes or sun exposure often trigger it. Pregnancy makes melasma especially common among women.
• Age spots, also known as liver spots, form after years of sun exposure. These flat, dark patches tend to show up on the face, hands, and shoulders.
• Post-inflammatory hyperpigmentation (PIH) develops when the skin darkens after injury or inflammation. Acne, eczema, or even irritation can trigger it. PIH fades slowly and is more stubborn on darker skin tones.

Best Treatment for Pigmentation Removal

The best treatment for skin pigmentation depends on its type and severity. For some, topical creams containing ingredients such as hydroquinone or retinoids may be effective. For deeper pigmentation issues, treatments such as laser therapy or chemical peels provide more precise results.

At SIAN, we address common issues such as pigmentation on face, melasma, and sunspots through targeted treatment plans. We tailor advanced therapies, including laser resurfacing and medical-grade facials, to meet individual needs. They support faster cell renewal and help reduce dark patches. A consistent routine that includes skincare for pigmentation can help maintain results and prevent recurrence. Maintenance is just as important as correction to avoid relapse, particularly for hormonal pigmentation.

Hypopigmentation

Hypopigmentation means pigment loss in the skin, often seen as lighter areas. The duration of hypopigmentation varies and depends on what caused it.

Vitiligo is a well-known condition that results in hypopigmentation. In vitiligo, the immune system attacks melanocytes, leaving behind smooth, pale patches of skin.

Another example is albinism, a genetic disorder where the body produces little to no melanin from birth. Fungal infections, such as tinea versicolor, may also lead to temporary light patches on the skin.

People experiencing hypopigmentation often describe it as losing pigment in skin, especially after burns, infections, or other injuries. Though not dangerous, it can increase sun sensitivity and affect emotional wellbeing. Sunscreen and cosmetic camouflage are frequently recommended to manage the appearance of lighter patches.

What Causes Skin Pigmentation Disorders?

Pigmentation disorders can develop for many reasons. Sunlight, hormones, injury, and genetics all play a role. Identifying the cause helps guide treatment.

• Sun exposure increases melanin production and often makes existing pigmentation more visible.
• Hormonal changes during pregnancy, menopause, or while using birth control can trigger excess melanin.
• Medical conditions such as thyroid disorders or Addison’s disease may cause noticeable shifts in skin tone.
• Liver or kidney problems can sometimes affect pigmentation, especially when combined with other health issues.
• Skin trauma—including cuts, burns, or acne—can lead to post-inflammatory hyperpigmentation.
• Medications and infections may also interfere with how the skin produces melanin.
• Genetics influence your skin’s baseline tone and how it reacts to damage or inflammation.
• Ethnicity affects both your risk for pigmentation issues and how your skin responds to treatment.

How is Skin Discoloration Treated?

At SIAN Skincare & Laser Clinic, doctors take a personalized approach to treating skin discoloration. Each patient begins with a full skin examination. Based on the findings, the doctor designs a customized plan. That may include lifestyle changes, topical creams, oral supplements, and advanced laser therapies.

When brown spots or freckles are present, doctors treat them with a 523nm Nd:YAG laser or a CO₂ laser. For patchy melasma (melasma plaques), doctors use a 1064 nm wavelength Nd:YAG laser to target deeper pigment layers.

SIAN Skincare & Laser Clinic currently uses the Helios laser system for pigmentation treatment. Helios delivers strong results and offers advantages over traditional CO₂ lasers.

Daily sunscreen use is critical to protect the skin during and after treatment. Lifestyle adjustments also support healing. A balanced diet, regular hydration, and gentle skincare all help maintain progress. Doctors also advise patients to avoid drinking, smoking, and sleep deprivation, as these habits can worsen uneven pigmentation.

What Are Some Ways to Prevent Skin Discoloration?

To help prevent skin discoloration, follow these simple steps:

• Know your triggers. Identify what worsens your skin pigmentation, such as sun, hormones, or skin irritation.
• Use sunscreen daily. Apply SPF 30 or higher every morning. Reapply during the day if needed.
• Dress for protection. Cover up with long sleeves, sunglasses, and broad hats when spending time outside.
• Be gentle with your skin. Skip harsh scrubs and strong products. Use cleansers and exfoliants that suit your skin type.
• Choose smart skincare. Choose products that feature brightening agents such as vitamin C, alpha arbutin, or niacinamide. These ingredients help control melanin and fight damage.
• Take care of your health. Sleep well, drink water, and manage stress. Visit a skincare professional regularly.

When Should You See a Dermatologist?

While some pigmentation issues fade with time or treatment, others may indicate deeper concerns. If a patch of pigmentation begins to itch, expand, or change in appearance, it’s time to seek expert evaluation.

Early consultation helps identify the underlying cause and ensures access to the most effective pigmentation treatment options.

At SIAN Skincare & Laser Clinic, dermatologists offer expert diagnosis and care. Whether the goal is skin pigmentation removal or ongoing management, personalised plans provide clear pathways to healthier, more even-toned skin.
