Age spots and sun exposure: Why sun protection is so important

Age spot sun

Age spots, also known as senile lentigines, are dark patches on the skin often associated with the natural ageing process and sun exposure. They can appear on different areas of the body, especially on areas that have been exposed to the sun over the years. In this blog post, we will take a closer look at the link between age spots and sun exposure and explain why sun protection plays a crucial role in preventing and reducing age spots.

Why does the development of age spots occur?

Age spots are caused by an accumulation of melanin, the pigment responsible for the colour of the skin. Sun exposure is one of the main triggers for the development of age spots. The sun's ultraviolet (UV) rays stimulate the melanocytes in the skin to produce more melanin to protect the skin from damage. Over time, this excessive melanin production can lead to an uneven distribution of pigment and cause age spots.

Why is sun protection so important?

  1. Prevention of age spots: Sun protection is the key to preventing age spots. By using sunscreen with an appropriate sun protection factor (SPF), you protect your skin from the sun's harmful UV rays. This reduces the stimulation of melanocytes to produce more melanin and reduces the risk of developing age spots.
  2. Minimisation of existing age spots: Regular use of sunscreen products can help prevent existing age spots from getting worse. Sun exposure can increase the intensity of the spots and increase their visibility. By protecting your skin from the sun, you can reduce the risk of pigmentary shifts and further development of age spots.
  3. Maintain skin health: Sun protection is not only important for preventing age spots, but also for the overall health of your skin. Overexposure to the sun can lead to premature ageing, wrinkling, sunburn and even skin cancer. Proper sun protection helps minimise these harmful effects and maintain the health of your skin.

Tips for effective sun protection:

  • Use a broad-spectrum sunscreen with an SPF of at least 30.
  • Apply sunscreen generously to all exposed skin areas, including the face, neck, arms and hands.
  • Renew the sunscreen every two hours, especially after swimming or sweating.
  • Wear protective clothing such as hats, sunglasses and long-sleeved shirts.
  • Avoid excessive sun exposure, especially during peak hours between 10am and 4pm.


Sun exposure plays a crucial role in the development of age spots. By using sunscreen, you can protect your skin from harmful UV rays and reduce the risk of age spots. Remember that sun protection is not only important for preventing age spots, but also for the overall health of your skin. By incorporating sun protection measures into your daily routine, you can save your skin from premature ageing and other harmful effects of the sun.

Questions and answers about age spots and the sun

Can I avoid age spots by only using sunscreen on sunny days?

No, age spots can also appear in cloudy weather or in the shade. UV rays also penetrate through clouds and can damage the skin. Therefore, it is important to apply sunscreen daily, regardless of the weather.

Can I prevent age spots by wearing sunglasses and hats?

While sunglasses and hats protect certain areas such as the face and eyes from direct sunlight, they do not provide complete protection from age spots. Using sunscreen on all exposed skin is still important to minimise the risk of age spots.

Which sun protection factor (SPF) is best for protection against age spots?

It is recommended to use a sunscreen with a sun protection factor (SPF) of at least 30. A higher SPF provides additional protection, but the key is to use it regularly and reapply every two hours.

Can I get rid of my existing age spots by using sunscreen?

Sunscreen can help slow the progression of existing age spots and reduce their visibility. However, it is unlikely that sunscreen alone will completely remove existing age spots. In such cases, you can consult a dermatologist to discuss appropriate treatment options.

Are there other measures I can take to prevent age spots?

In addition to sunscreen, you can also take other precautions to reduce the risk of age spots. These include wearing protective clothing, avoiding excessive sun exposure during peak hours and seeking shade when the sun is most intense. A healthy lifestyle with a balanced diet, adequate hydration and stress management can also contribute to skin health.
