AROUND 90% OF SKIN CANCERS ARE CAUSED BY DAMAGE FROM OVER-EXPOSURE TO ULTRAVIOLET RADIATION, MAKING THE DISEASE ALMOST ENTIRELY PREVENTABLE!


Almost all skin cancers are caused by over-exposure to UVR. All skin types can be damaged by UVR. Damage is permanent, irreversible, increases with each exposure and can result in death.
The sun emits three types of UV rays - UVA, UVB and UVC. UVC rays are blocked by the ozone layer, whilst UVA and UVB both reach the earth’s surface and penetrate our skin.
UVB rays reach the outer layer of the skin (the epidermis) – they are known as ‘burning rays’ and are the primary cause of sunburn and skin cancer.
UVA rays penetrate the middle layer of the skin, (the dermis) they also contribute to skin damage and skin cancer and are also responsible for around 80% of the visible signs of premature ageing.
UVA levels are consistent during daylight hours, maintaining almost the same level of strength throughout each day and throughout the year. UVA accounts for up to 95 per cent of the UV radiation that reaches the earth’s surface and it can penetrate (pass through) cloud cover and most glass and plastic. During our lifetime, we are therefore all exposed to high levels of UVA radiation.
Most of the sun’s UVB radiation is absorbed by the ozone layer in the earth’s atmosphere and levels vary throughout the day. UVB becomes stronger between 10 am and 4 pm, it intensifies during the summer months, the closer to the equator we are and whilst it can penetrate cloud cover, it cannot penetrate solid objects such as glass and plastic.


Although skin cancer is much more common in fairer skin types that tend to burn more easily, people of all colours, including those with dark brown and black skin, can get skin cancer. Even if you never sunburn, you can get skin cancer.
Darker skin types that tan easily and rarely or never burn have more melanin, a natural pigment that our skin produces when we are exposed to UV radiation and exists solely to protect our skin from harm.
However, even if we tan rather than burn, the simple fact that our skin changes colour is a sign of damage – it’s a warning sign that our body is working hard to defend itself from the harmful effects of the sun.
WHEN IT COMES TO SUN EXPOSURE, THE MESSAGE IS CLEAR - THERE IS NO SAFE WAY TO GET A TAN!

UV radiation from the sun can reach us on the ground from three sources: Directly from the sun, scattered from the open sky and reflected from the environment around us. This means that you can still receive a substantial amount of UV exposure that can burn your skin and damage skin cells, even if you are shaded from direct sunlight.
UV reflections off snow can increase the intensity of UV reaching our skin and eyes by over 80%! You can burn your skin just as quickly on the ski slopes as you can on a Mediterranean beach! Take extra care if you enjoy winter sports to ensure your skin and eyes are protected.
Water, sand (particularly white sand) and light, smooth surfaces like those you would find round a swimming pool are also highly reflective. These surfaces can almost double the strength of UV reaching our skin and eyes. In addition, up to 50% of UVA and UVB passes through the upper 50cm of water. If you enjoy water sports, are swimming , sat on the beach or around the pool, be extra careful to take measures to protect your skin and eyes and be especially vigilant with children who are highly susceptible to sun damage.


Intense or cumulative UV exposure can affect our eyes in a number of ways:


Cumulative sun exposure is the main cause of non-melanoma skin cancers, while sunburn plays a clear role in the development of melanoma.
Sunburn, particularly in childhood or adolescence can significantly increase your risk of developing melanoma. Skin damage builds up over time starting with your very first sunburn and the more you burn, the greater your risk of developing melanoma.
Sunburn (reddening of the skin) is a reaction to over-exposure to UV radiation caused by the sun and/or sunbeds. Our skin turns red within 2-6 hours of being burnt and continues to develop for the next 24 to 72 hours. The superficial layers of the skin release chemicals that cause our blood vessels to expand and leak fluid causing swelling, pain and redness. Without sun protection, UV radiation penetrates deep into the layers of the skin causing cumulative and irreparable damage to the skin cells.


There is so much evidence to support this, that the International Agency for Research on Cancer (IARC) has classified sunbeds as a Group 1 carcinogen. This is its highest cancer risk category.
Sunbed use at any age significantly increases the risk of developing skin cancer including the most serious form melanoma. However, the risk is even greater when used at a younger age. A review by IARC found that first exposure to sunbeds before the age of 35 years increases the risk of melanoma by an alarming 75 per cent and if used before the age of 30 the risk is further increased.
Sunbeds use fluorescent bulbs that emit mostly UVA radiation, but at much greater intensities than natural sunlight to enable the skin to tan quickly. Whilst UVB emitted from sunbeds may approach levels similar to that of bright sunlight, it is the intensity of UVA radiation that penetrates deeper into the layers of the skin (the dermis) to also be aware of.
For many years scientists believed that UVB radiation was the most harmful due to the links between sunburn and melanoma. However, since the late 1980s we have known that UVA radiation also increases the risk of cell damage and skin cancer and by using a sunbed you are significantly increasing the amount of UVA your skin is exposed to, thereby significantly increasing your risk.
Damage from both UVA and UVB is cumulative - it increases with each and every use and it is irreparable. Once the tan fades, the damage remains and it can result in very serious consequences over time.

There are two forms of vitamin D – vitamin D2 and vitamin D3 and to remain in good health it is important to ensure our bodies receive adequate levels of both.
Vitamin D2 is ingested from a healthy balanced diet and can be derived from everyday foods such as: Egg yolks and fatty fish like; trout, mackerel, salmon or tuna, as well as cod liver oil, or fortified milk, juices and cereals.
Vitamin D3 however, is most efficiently produced when our skin is exposed to the sun’s UVB radiation. Although environmental and personal factors greatly affect vitamin D3 production in the skin (meaning there is no ‘one-size-fits-all’ level of exposure) for most, vitamin D3 can efficiently and sufficiently be produced in around 15-20 minutes a day - from doses of UV exposure, below those which cause reddening of the skin or sunburn.
Vitamin D deficiency and supplements.
Vitamin D deficiency is not uncommon and can affect all age groups, races and ethnic backgrounds. It’s also not possible to achieve sufficient levels of vitamin D through diet alone. The NHS therefore recommends that we should all (from pre-school aged children, to the elderly) consider taking Vitamin D daily supplements, to keep our bones and muscles healthy.
Taking vitamin D supplements is safe as long as you stick to the recommended dosage as too much Vitamin D can cause health problems. However, if you have any health conditions, take any other medication or have allergies, it’s important to take advice from your GP first.


The ultraviolet index, or UV Index, is an international standard measurement of the strength of sunburn-producing ultraviolet (UV) radiation at a particular place and time.
The risk of harm from unprotected sun exposure is categorised by five numerical and colour coded values. The higher the number, the stronger the UVR and the less time it takes damage to occur. When the UV index reaches 3 or above, sun protection measures should be taken to protect our skin and eyes.
You can use this App to find out the UV Index and the 2 day UV forecast in your location, or for any location across the globe. You can also set alerts to let you know when the UV reaches 3 and when it reaches its daily peak in addition to advice on what sun protection measures are required. You can also set 2 hourly sunscreen reminders to help you take charge of your skin health.


Remember it’s not just sunbathing that puts you at risk, but being in the sun without adequate protection. If you regularly take part in outdoor hobbies or sports, or work outdoors, you could be at greater risk. Make sure you use all five S’s of sun safety and remember the golden rule is to NEVER BURN!

We tend to associate winter with low UV levels and no requirement for sun protection. However, ask any dermatologist if they recommend daily use of sunscreen, all-year-round - and their answer will be yes!
Whilst UVB levels may be lower, the earth’s ozone layer (which acts as our sunshield), is at its thinnest during winter months. In addition, UVA rays remain consistent throughout each season and throughout each day. Therefore daily use of sunscreen will not only help protect your skin from the damaging effects of UV radiation, it will also help to prevent around 80% of the visible signs of premature ageing.
ENJOY WINTER SPORTS? BE WARNED!
Winter sports enthusiasts are at a particularly high risk of sun damage to both their skin and eyes. UV rays can be just as damaging on the ski slopes as they are on a hot, sunny beach! This is because UV radiation increases by approximately 10% with every 1,000m in altitude AND snow and ice significantly reflects UV, increasing the intensity penetrating our skin and eyes by over 80%!
If you enjoy winter sports make sure you pay special attention to protecting exposed skin with an SPF 30+ sunscreen, with 4 or 5 star UV protection and wear high quality eye protection that carries either an EPF (Eye Protection Factor) of 9 or 10, or is labelled CE UV400 or above.




Sunburn in childhood is strongly linked to the development of melanoma in later life. A child’s delicate skin is highly susceptible to sun damage and can burn within minutes.
Extra care should be taken to safeguard children against UV exposure and by acting as responsible role models when it comes to sun protection will help to influence their behaviours, for a positive, sun safe, skin cancer free future.


During school hours it is essential that children have access to a quality sunscreen and sun hat for use during break times, PE lessons and outdoor activities. Even if we apply sunscreen to our children prior to going to school, after 2 hours it will become ineffective, leaving them unprotected during peak UV hours when they are likely to spend longer periods of time outdoors.
Whilst parents should ensure children are equipped with appropriate sun protection items, schools have a duty of care to ensure children are safeguarded against the damaging effects of UV during school hours and implement a robust policy to reflect their commitment to both safeguarding and education.
Skcin operate a nationally accessible educational intervention programme that is free for all primary schools. The Sun Safe Schools programme provides primary schools with comprehensive resources and guidance to help them achieve an annual accreditation that outlines their commitment to:
PROTECTION: creating a robust policy and providing an environment that enables children and staff to stay safe in the sun. EDUCATION: teaching children about sun safety to increase knowledge and influence behaviour. COLLABORATION: working with parents, the management structure and the wider community to reinforce awareness about sun safety and skin cancer prevention.
Via the Sun Safe Schools national accreditation programme we are not only helping schools fulfil their obligations, but empowering children to recognise the importance of sun safety by learning to take charge of their own skin health - preventing skin cancer for our future generations and those to come.

When entrusting babies and toddlers to the care of a nursery or pre-school setting it is essential to ensure they have access to appropriate sun protection measures throughout the day to safeguard them against the damaging effects of UV.
Just like schools, these setting also have a duty of care to ensure a robust policy and sun safe environment is in place and that it is communicated effectively to parents so they can ensure they receive the required level of support.
Skcin operate a nationally accessible educational intervention programme that is free for all Nursery and pre-school settings. The Sun Safe Nurseries programme provides settings with comprehensive resources and guidance to help them achieve an annual accreditation that outlines their commitment to:
PROTECTION: creating a robust policy and providing an environment that enables children and staff to stay safe in the sun. EDUCATION: teaching early learners about sun safety to increase knowledge and influence behaviour. COLLABORATION: working with parents, the management structure and the wider community to reinforce awareness about sun safety and skin cancer prevention.
Skcin are successfully working with thousands of settings across the UK to help them fulfil their obligations and prevent skin cancer through education.

Frequent, prolonged periods of time spent outdoors without adequate protection makes outdoor workers twice as likely to contract skin cancer from exposure to the sun than indoor workers. Therefore outdoor workers should take care to protect their skin from the damaging effects of UV radiation.
The Health & Safety at Work Act states that every employer has a legal duty to safeguard, as far as is reasonably practical, the health of their employees - this includes exposure to UV radiation which is a known carcinogen to humans.
Employers therefore have a duty of care to educate their employees about the health implications the sun can have, the importance of appropriately protecting their skin and to ensure the provision of appropriate protection from the sun.
Skcin has developed and operate a national accreditation programme specifically designed for employers of outdoor workers to assist them in their duty of care to safeguard their outdoor workers and provide education to influence behaviours.
The Sun Safe Workplaces programme provides extensive resources to help employers assess the level of risk, implement a suitable sun protection policy and educate their workforce about the risks associated with UVR, the importance of personal sun protection measures and how to check their skin for the early signs of both melanoma and non-melanoma skin cancers.
