What is Skin Pigmentation?
Skin pigmentation is the result of melanin production and distribution in the skin. When melanin is produced in excess or unevenly, it can lead to:
-
Hyperpigmentation: Dark spots or patches due to increased melanin.
-
Hypopigmentation: Lighter areas caused by reduced melanin production.
Common pigmentation disorders include:
-
Melasma: Brown or grey-brown patches, often linked to hormonal changes.
-
Sunspots (Solar Lentigines): Caused by cumulative sun exposure.
-
Post-Inflammatory Hyperpigmentation (PIH): Dark marks following acne, eczema, or skin trauma.
-
Vitiligo: Loss of pigment resulting in white patches.
Identifying the type of pigmentation is essential for selecting the right treatment.
Signs and Symptoms of Pigmentation Issues
Symptoms vary based on the underlying cause and may include:
-
Dark patches or spots on the face, arms, or hands
-
Light patches or areas lacking pigmentation
-
Freckles or sunspots, especially after sun exposure
-
Blotchy or uneven skin tone
-
Redness or irritation accompanying pigmentation changes in some cases
If you notice changes in your skin’s pigmentation, consult a dermatologist for a proper diagnosis.
What Causes Uneven Skin Pigmentation?
Multiple factors can influence pigmentation:
-
Sun Exposure – UV rays stimulate melanin, leading to sun-induced spots.
-
Hormonal Changes – Pregnancy, oral contraceptives, and hormone therapy can trigger melasma.
-
Skin Injury – Healing from acne, cuts, or burns can leave behind dark marks.
-
Ageing – Older skin tends to show sun damage more visibly.
-
Genetics – A family history of pigmentation disorders may increase your risk.
-
Medical Conditions – Disorders like vitiligo and Addison’s disease can affect pigmentation.
-
Medications – Certain drugs may alter melanin production as a side effect.
At Shine Dermatology, we carry out a detailed assessment to understand the cause and develop a suitable treatment plan.
