PIGMENTATION

 

Pigmentation refers to the colouring of the skin, which is determined by the amount and distribution of melanin, a pigment produced by melanocyte cells in the skin.

 

While melanin production is a natural, protective response to UV exposure, uneven distribution or overproduction can result in dark spots, patches, or an uneven complexion. These changes can occur in the outermost layer (epidermal) or deeper layers (dermal) of the skin and may present as either cosmetic concerns or indicators of underlying skin conditions.

 

 

 

Melasma: Often triggered by hormonal changes (such as pregnancy, oral contraceptives, or hormone therapy), melasma presents as symmetrical brown or grey-brown patches, commonly on the face. It is more prevalent in women and those with darker skin types.

 

 

 

Freckles (Ephelides): Small, light brown spots that are usually genetic and become more noticeable with sun exposure.

 

 

 

 

Post-Inflammatory Hyperpigmentation (PIH) and Erythema (PIE): This occurs following trauma or inflammation to the skin, such as acne, eczema, or injury. It is especially common in individuals with medium to dark skin tones.

 

 

 

Solar Lentigines (Sun Spots or Age Spots): Caused by cumulative sun exposure, these flat, brown lesions appear on sun-exposed areas like the face, hands, shoulders, and chest. They are more common with age. Solar lentigines are most commonly confused with MELANOMA skin cancers. ALWAYS get a qualified medical professional to assess pigmented lesions prior to having them treated.

  Melanoma

Lentigoes and Melanomas can be difficult to tell apart, but a trained dermoscopist will have a higher chance of delineating between the two. Don’t risk your life.

 

 

Pigmented Birthmarks and Conditions: Such as café-au-lait spots or nevus of Ota, which are congenital and vary in intensity and presentation.

 

 

 

 

1. Sun Exposure (UV Radiation): The primary cause of uneven skin tone and dark spots, UV radiation triggers excess melanin production, especially in unprotected skin.

 

 

2. Hormonal Changes: Fluctuations in oestrogen and progesterone levels—common during pregnancy, use of hormonal contraception, or menopause—can stimulate melanin overproduction, leading to melasma.

 

 

3. Skin Trauma or Inflammation: Acne, cosmetic procedures, burns, or injuries can trigger an overproduction of melanin as the skin heals, resulting in PIH.

 

 

4. Genetics and Skin Type: Individuals with darker skin tones naturally have more active melanocytes, making them more susceptible to conditions like PIH and melasma.

 

 

5. Medications and Chemicals: Certain drugs (e.g., antibiotics, anti-seizure medications) and photosensitising agents can increase the risk of skin discolouration.

 

 

6. Ageing: As skin ages, its ability to repair UV-induced damage decreases, making issues like sun spots and uneven tone more likely to develop.

 

 

7. Underlying Medical Conditions: Disorders such as Addison’s disease, haemochromatosis, or certain endocrine imbalances can contribute to abnormal pigmentation.Underlying Medical Conditions: Disorders such as Addison’s disease, haemochromatosis, or certain endocrine imbalances can cause skin discolouration or darkening.

 

 

 

 

Effective management begins with identifying the underlying cause. Treatment may include:

 

Sun protection: Daily use of broad-spectrum SPF 50+ is critical.

 

Topical treatments: Ingredients such as vitamin C, retinoids, azelaic acid, kojic acid, and hydroquinone (in some cases) can help reduce pigmentation.

 

Oral therapies: This includes the use of TXA.

 

Professional treatments: Chemical peels, laser therapies, microneedling, and BroadBand Light (BBL) can improve uneven skin tone by targeting excess melanin and promoting skin renewal.

 

Lifestyle adjustments: Managing hormone levels, avoiding picking or squeezing acne, and using gentle skincare products can help prevent further skin discolouration or dark spots.
