What is Pigmentation? Why Your Skin Color Changes


Embark on a fascinating journey into the captivating world of skin pigmentation causes! Our skin, with its myriad hues, has long fascinated humanity. But beneath its surface lies a complex process—pigmentation. It’s not merely about the colour of our skin and the shades we wear; it’s a profound understanding of our body’s intricate workings. Join us as we delve into the science behind pigmentation, exploring how it influences our skin’s colouration and why it’s crucial for more than just aesthetics.

What is pigmentation?

Skin pigmentation is the skin’s natural colouring and is produced by melanin, a substance in the body which produces colour for the hair, eyes and skin. Did you know that there is more than one type of Pigmentation? Hypopigmentation means there is less melanin in the skin, causing the skin to become lighter. Hyperpigmentation is the opposite – when the skin produces excess melanin, it results in darker patches of skin. Depigmentation is where there is no melanin and the skin turns white, as in the auto-immune condition vitiligo. Hence, it all depends on the amount of melanin produced – and that is why your skin colour changes.

Factors influencing Skin Colour Changes:

There is an intricate interplay of factors influencing changes in your skin colour.

Genetics: DNA from both parents determines whether a baby will have dark, light or wheat-coloured skin.

Sun exposure: Sunlight causes the skin to produce more melanin, which darkens the skin. Overexposure to UV rays can cause ageing skin and dark spots.

Gender also plays a role, with men typically darker due to women’s increased need for vitamin D and calcium during pregnancy and breastfeeding. This extra intake can cause skin colour to lighten.

Melanogenesis, the production of melanin, protects against UV radiation, explaining darker skin in tropical regions.

Environmental factors like dust, pollution and extreme temperatures can lead to pigmentation issues and changes in skin tone.

Causes of Skin Pigmentation:

Skin pigmentation changes can stem from various factors.

Hyperpigmentation, where patches darken, often arises from skin inflammation, medication use (e.g., minocycline, birth control pills), hormone disorders like Addison’s disease, or sun exposure. Pregnancy can lead to melasma, while conditions like acanthosis nigricans (velvety darkening of the skin) and certain birthmarks may also contribute.

Conversely, hypopigmentation, resulting in lighter patches, can be caused by inflammation, fungal infections like tinea versicolor, vitiligo, certain medications or conditions like psoriasis, characterized by patches of abnormal skin.

Understanding these triggers aids in managing pigmentation concerns effectively.

At Home Care:

Both over-the-counter and prescription creams can aid in lightening the skin. Look for creams containing natural plant-based ingredients like liquorice extract or Bakuchiol. Follow instructions diligently and avoid prolonged use, limiting application to three weeks at a time. Darker skin tones require careful consideration when using these products. Cosmetics can also provide temporary coverage for skin discoloration. Remember to protect your skin from sun exposure by using sunscreen with SPF 30 or higher to prevent further pigmentation. Note that abnormally dark skin may persist despite treatment efforts.

Tips for Maintaining Healthy Skin:

Maintaining healthy skin requires a holistic approach.

Consistent skincare with suitable cleansers and moisturisers helps manage pigmentation. Prioritise sun protection with daily broad-spectrum sunscreen, protective clothing, and shade.

Adopt healthy habits like hydration, antioxidant-rich diet, exercise and stress management for overall skin health.

Consult a dermatologist for personalised advice on effective pigmentation management.

Seeking Professional Advice:

When noticing significant or persistent changes in skin colour, it’s vital to seek guidance from a dermatologist or skin care for pigmentation professional. They provide personalised advice and effective treatment options tailored to individual concerns.

If you observe any skin discoloration causing worry, persistent darkening or lightening, or any changing skin sore or lesion, it’s advisable to contact a medical professional promptly. Their expertise ensures a personalised approach to address hyperpigmentation, hypopigmentation or other skin colour changes effectively.

Early intervention ensures timely management, potentially addressing underlying issues and maintaining skin health.
