Signs and Symptoms of pigmentation and sun spots
Pigmentation can vary in size and colour however they are usually darker than the skin although they can be pink in colour. Fair skinned individuals are more likely to be affected by moles and freckles which can also be attributed to hereditary factors. Almost everyone has at least some kind of pigmentation whether it be freckles, sun spots, moles or birth marks. There are no real symptoms that cause pigmentation and they may even appear overnight, however in some cases what may appear like normal pigmentation may also be cancerous. Therefore it is imperative that excessive exposure to the sun is approached in a safe manner using a highly protective sunscreen with an SPF of 50+, whilst those with a history of cancer in the family can be put at greater risk.
Causes of Pigmentation and Sun Spots
Pigmentation is caused by an excessive amount of melanin found in certain skin cells. These skin cells generally carry higher levels of melanocytes which produce the melanin causing the skin to appear pigmented in certain areas.
Pigmentation can be attributed to environmental factors such as:
- Excessive exposure to the sun
- The contraceptive pill
- Hereditary factors
