Pigmentation Removal in Singapore

Skin pigmentation refers to changes in skin colour caused by an imbalance in melanin, which is the pigment responsible for giving skin its natural tone. This imbalance can result in either excess or loss of melanin, leading to areas of discolouration that appear darker (hyperpigmentation) or lighter (hypopigmentation) than the surrounding skin.

Excess melanin production is often triggered or worsened by repeated sun exposure. In Singapore, this may be more common due to consistently high UV radiation levels linked to the country’s proximity to the equator. Over time, cumulative UV exposure may contribute to persistent dark patches or uneven skin tone that become increasingly difficult to treat.

Skin pigmentation can occur superficially in the epidermis (the outer layer of the skin), deeper in the dermis (the middle layer of skin), or as a combination of both.

1. Sun Damage

   Sunlight is the leading cause of hyperpigmentation, as UV rays from the sun stimulate melanocytes, the cells responsible for producing melanin. Prolonged sun exposure triggers increased melanin production as the body’s way of protecting your skin against harmful UV rays. However, excessive exposure to the sun also results in hyperpigmentation irregularities like sun spots or age spots. Sun exposure can also cause dark spots or patches on the skin to become more pronounced.

    

2. Hormonal Fluctuations

   Your body may experience hormonal changes during pregnancy, when taking oral contraceptives like birth control pills, or when undergoing hormonal therapies, which influence the body’s melanin production. This hormonal imbalance commonly manifests as melasma, patchy brown or grey-brown discolouration typically affecting the face. 

    

3. Skin Inflammation or Injury

   Skin conditions, injuries, or surgery can cause inflammation that activates melanocytes, resulting in pigmentation changes. Depending on how the skin responds, this process can lead to either post-inflammatory hyperpigmentation, where dark spots develop as the skin heals, or post-inflammatory hypopigmentation where melanin production is suppressed, leaving behind lighter patches. Common triggers include acne, eczema, lupus, and burns. Individuals with darker skin tones are more prone to either outcome due to their naturally higher melanin content.

    

4. Age

   Physiological changes are a primary cause of the increase in age spots in those over 40 years old. The number of melanocytes decreases with age, while the remaining cells grow larger and distribute melanin more unevenly. The change to melanin distribution that occurs as we age can lead to the development of age or liver spots, often caused by years of accumulated sun exposure.

    

5. Reaction or Exposure to Medications, Chemicals, and Drugs

   Certain medications or chemical exposures can interfere with melanin production in both directions. Antibiotics, antimalarial drugs, tricyclic antidepressants, chemotherapy drugs, anti-seizure drugs, and some topical treatments may cause patches of your skin to turn grey. Others, like topical corticosteroids or excessive use of chemical agents like hydroquinone, may suppress melanin production and lead to uneven lightening of the skin.
