Have you ever wondered what sunspots, also known as solar lentigines, liver spots and age spots, really are? Let’s take a closer look at these common skin spots.
Sunspots, or age spots, are areas of skin that have darkened due to prolonged exposure to the sun’s harmful UV rays.
They often appear on areas of the skin that are frequently exposed to the sun, such as the face, hands, arms, and shoulders. These spots are typically flat and have a range of colours from light brown to black.
What Causes Sunspots to Appear on the Skin?
So, what exactly causes these sunspots to pop up on our skin?
Sunspots are primarily caused by the overproduction of melanin, the pigment responsible for giving our skin its colour.
When our skin is exposed to the sun, it triggers the production of melanin as a defense mechanism against UV rays. Over time, this excess melanin can clump together and form sunspots on the skin.
Are Sunspots Harmful or Just a Cosmetic Issue?
Now, the big question – are sunspots harmful, or are they just a cosmetic concern? In most cases, sunspots are harmless and are considered a cosmetic issue.
They are often seen as a natural part of the aging process and are generally benign. However, it’s essential to keep an eye on any changes in sunspots, as they can, in some cases, be an indication of more serious skin issues.
This is why regular skin checks are crucial to ensure that sunspots are not a sign of something more concerning, such as skin cancer.
If sunspots are considered harmless, why should we worry about them?
While sunspots may seem harmless, it’s crucial not to overlook them.
Early-stage skin cancers can appear like moles or sunspots. Consequently, dismissing a darkened area on the skin may delay treatment for potential skin cancer. especially melanoma.
Keep an eye on your skin and have your skin checked by experts if you notice any changes in your skin, as early detection can significantly improve outcomes.
What’s it? Is it a sunspot, freckle, or mole?
Do you have spots on your skin? This is a fairly common problem. Do not worry. However, let’s explore the characteristics of different skin spots
Moles:
- Caused by clusters of melanocytes in the skin.
- Generally raised and can vary in colour from flesh-coloured to dark brown.
- Can develop over time or be present at birth.
Freckles:
- Result from an excess production of melanin due to sun exposure.
- Flat, small, and often found in groups.
- Typically appear at a young age and may fade over time.
Sunspots:
- Develop due to excessive sun exposure causing melanin production.
- Larger than freckles and usually appear as single spots.
- Tend to develop later in life
Keep in mind that moles, freckles and sunspots usually don’t indicate any health concerns, but some dark spots can be signs of skin cancer.
Is it sunspot or Melanoma?
The difficult part is identifying whether a spot on the skin is a harmless sunspot or a potentially dangerous melanoma.
Although many skin spots are benign and may result from sun exposure or aging, it’s important to be aware of changes in size, shape, colour, or texture that indicate cancer.
Here’s some information to help distinguish between the two:
Sunspots (Solar Lentigines, liver spots, age spots):
- Uniform appearance and colour: Sunspots usually have a uniform colour and shape (flat and oval), with well-defined borders.
- Small to Medium Size: They are generally small to medium in size and may appear in clusters.
- No Changes Over Time: Sunspots typically remain stable in size, shape, and colour over time.
Melanoma:
Melanoma develops from melanocytes, the cells that produce melanin.
It can occur anywhere on the body, including areas not exposed to the sun.
Signs of melanoma include:
- Asymmetry: One half of the spot does not match the other half in size, shape, or colour.
- Irregular Borders: The borders of the spot are uneven, scalloped, or poorly defined.
- Varied Colours: The spot may contain multiple colours or shades, such as brown, black, blue, red, or white.
- Diameter: Melanomas are typically larger than a pencil eraser (about 6mm) but can be smaller.
- Evolution: The spot may change in size, shape, colour, or elevation over time. It may also itch, bleed, or become tender.
It’s important to consult a dermatologist as soon as you notice any changes in a spot on your skin.
Remember that early detection and treatment of melanoma significantly improve the chances of successful outcomes.

- Chemical Peels
- Laser Therapy
