Laser Treatment for Skin Pigmentation
What is skin pigmentation?
Skin pigmentation refers to the colouring of the skin, which is influenced by the deposition of a pigment called melanin. Melanin is produced by specialised cells known as melanocytes. When these cells are damaged or unhealthy, melanin production is affected, leading to skin pigmentation disorders.
Some disorders only affect specific areas or patches of the skin, while others can affect the entire body. Skin pigmentation disorders can impact individuals of all races, genders, and ages.
What causes skin pigmentation?
In some cases, the causes of skin pigmentation disorders are easily identifiable, while others remain unclear. Here are some common causes:
Sunspots (Solar Lentigens): These form due to an increase in melanin (skin pigment) from exposure to ultraviolet (UV) radiation via sunlight. UV radiation stimulates melanin production, and excessive melanin can concentrate in one spot, leading to sunspots.
- Melasma: This condition results from a combination of genetic factors, UV radiation, and hormonal influences. Women are more frequently affected than men, especially during pregnancy, due to the overstimulation of melanocytes by the female hormones estrogen and progesterone. Increased sun exposure during pregnancy can exacerbate melasma.
- Freckles: Typically caused by overexposure to sunlight, freckles tend to lighten or darken based on the amount of sun exposure.
Hori’s Naevus: This pigmentation disorder particularly affects Asians.
- Melanocytic Naevi (Moles): Moles arise from an abnormal cluster of melanocytes (pigment-producing cells) in the skin.
Understanding these causes can help in managing and treating various skin pigmentation disorders effectively.
What are the types of skin pigmentation disorders and their symptoms?
There are various types of skin pigmentation conditions. Here are some of the most common types and their symptoms:
Type | Symptoms |
|---|---|
Age Spots (Seborrheic Keratoses) | Raised sun spots with a rough texture, formed due to an increase in melanin over time from prolonged exposure to sunlight (UV radiation). |
Freckles | Clusters of melanised cells appearing as light brown or red spots, predominantly on the faces of people with fair skin. Freckles are triggered by sunlight exposure and tend to become more numerous with age. |
Hori’s Naevus | Predominantly affects Asian women in their 30s to 50s. It presents as brown and greyish spots, formed deep within the skin, typically over the upper cheeks and nasal bridge. |
Melanocytic Naevi (Moles) | Usually occur during childhood, adolescence, and early adulthood. These spots range from dark to light or even flesh-coloured. With age, they often become raised and dome-shaped. |
Melasma | Brownish, irregular patches that appear on the face, including the cheeks, forehead, temples, nasal bridge, upper lip, and jawline. These patches develop gradually over time and often disappear once hormone levels balance, such as after pregnancy. |
Nevus of Ota | A blue hyperpigmentation that occurs on the face and can also appear as spots in the eye. |
Sebaceous Hyperplasia | Yellowish lesions primarily found on the cheeks. These are benign tumours with a characteristic central dimpling. |
Sun (Solar) Lentigo / Liver Spots / Sun Spots | Hyperpigmentation blemishes caused by sun exposure, appearing on areas most exposed to the sun, such as the hands, shoulders, face, and arms. They range in colour from light brown to red or black. |

What are the benefits of laser skin treatment?
Laser therapy has become a popular and effective method for treating skin pigmentation. Advancements in technology have led to excellent results. Here are several benefits of using laser treatment for pigmentation and skin rejuvenation:
Safety and effectiveness: Laser treatment for pigmentation and skin rejuvenation is safe and effective when performed by a trained professional.
Skin tightening: This treatment can tighten your skin, giving you a more youthful appearance and an even skin tone.
Reversing skin damage: Laser therapy helps reverse signs of skin damage, such as brown spots, blotches, wrinkles, and freckles.
- Smoother skin: It reduces pore size, potentially giving your skin a smoother appearance.
