Suncreams

Why is Melanoma Focus campaigning to remove the VAT from sunscreens?

Melanoma Focus is calling on the Government to remove the Value Added Tax (VAT) for high-factor (30+) sunscreens to reduce the cost of this vital product for the general population, making it more accessible to those who cannot afford it.

Our 2023 research found that 67% of all respondents would use sunscreen more if it was 20% cheaper and worryingly, 1 in 10 people aren’t wearing sunscreen at all because it is too expensive. People on the very lowest incomes are less likely to wear sunscreen than any other economic group

The unaffordability of sunscreen is therefore a big concern.

What is the difference between UVA and UVB?

UVA and UVB are two types of light radiation that can cause
skin cancer.

Ultraviolet A (UVA) has a longer wavelength, and is mainly associated with skin aging.

Ultraviolet B (UVB) has a shorter wavelength and is mainly associated with skin burning. UVB is also responsible for making vitamin D.

Both UVA and UVB damage the DNA in skin cells, which lead to genetic defects and mutations which can cause skin cancer. Damage from UV exposure increases your risk of skin cancer over time. Your body may repair some of this DNA damage, however, the unrepaired damage and mutations may build up over time increasing your risk of skin cancer and melanoma. If you want to find out more about melanoma, see here.

What does the UV Index mean?

The UV index tells you how strong the sun’s UV rays will be; the higher the UV index, the greater the strength of the sun’s UV rays and the more likely you will burn.

The Met Office forecast uses the UV index to warn you of an increased risk to health from UK radiation.

When the UV Index is Moderate (3 or above) wear sunscreen.

The ‘Solar UV Index’ was developed by the World Health Organization. The Met Office UV forecasts include the effects of:

  • the position of the sun in the sky
  • forecast cloud cover
  • ozone amounts in the stratosphere

SunSmart Global UV App

The SunSmart Global App helps take the guesswork out of sun safety by showing you when ultraviolet (UV) levels are high enough to damage your skin.

Developed with input from leading international health and meteorlogical organisations, the app provides reliable, location-specific UV information and clear guidance on when to protect your skin.

The App:

  • Shows current UV levels at your location
  • Provides daily “sun protection times” when the UV index is 3 or above / moderate (the level where skin damage can occur)
  • Offers a 5-day UV forecast to help you plan ahead

This means you can make informed decisions about when to use sunscreen, seek shade or cover up to avoid unexpected sunburn.

What does SPF mean?

SPF or Sun Protection Factor is worked out under lab conditions to give an indication of how much protection a sun cream can offer.

The following equation is used:

Minutes to burn without sunscreen x SPF number = maximum sun exposure time

So if you would burn without sun protection in 10 minutes and you applied a factor 30 protection, you could theoretically be protected for up to 300 minutes.

BUT, it’s important to remember that lots of factors can affect how long your sun cream will protect you for. Sweating, swimming, clothes rubbing on your skin, your skin type and strength of the sun will all reduce your protection.

It’s also important to remember that laboratory tests are different to real world use; most people won’t apply sun cream as liberally or regularly as scientists do when testing sun creams. The SPF rating is simply a guide to the strength of protection and should not be taken literally to mean how much longer you can stay in the sun without burning. What’s most important is to apply the sunscreen generously and uniformly and to reapply every 2 hours.

What’s the difference between SPF 30 and SPF 50?

Interestingly, SPF50 offers only marginally better protection from UV radiation than SPF30 filtering out 98 per cent of UV radiation compared to 96.7 per cent blocked by SPF30.

Using SPF50 is not a substitute for applying sun cream less frequently.  SPF50 sunscreen still needs to be applied as liberally, re-applied every two hours (or after swimming, exercising and towel drying) and used in combination with other sun protection measures including sun protective hats, protective clothing, sunglasses and shade.

 

What does broad spectrum mean?

Broad spectrum sun cream protects you from both harmful UVA and UVB rays. This helps protect you against sunburn, premature aging and skin cancer, including melanoma.

In the UK, there should be a SPF and also a star rating from 1 to 5 – this star rating gives an indication of the protection against UVA rays- the higher the number of stars, the more balanced your protection will be. It is recommended that you use a 4 or 5-star protection and SPF 30 or above.

What’s the difference between a chemical and a mineral sunscreen?

A chemical or organic sunscreen contains active ingredients that protect your skin by absorbing the sun’s rays and causing it to undergo a chemical reaction that prevents it from damaging your skin. Most sun creams are chemical and you can check the active ingredients listed on the bottle. Physical or mineral sunscreens are usually hypoallergenic and may be a safer choice for people with sensitive skin. Physical or inorganic sunscreens protect your skin by deflecting the sun’s rays. These contain ingredients such as zinc oxide or titanium dioxide.

People with certain skin conditions, such as eczema, may find that some sunscreens can cause irritation or flare-ups. Finding the right product can sometimes be a process of trial and error, so it’s often a good idea to start with a small bottle to test.

Here are a few tips that may help you:

  • Choose a fragrance-free sunscreen.
  • Opt for a cream formulation rather than an aerosol spray.
  • Use a mineral sunscreen (those containing titanium dioxide or zinc oxide) to deflect UV radiation
  • Avoid rubbing in sunscreen, as this may trigger itchiness. Apply it in smooth, downward strokes, as you would apply an emollient.
  • Aim to use your emollient about half an hour before putting on your sunscreen.

What is the best sun cream?

Our sun safety ambassador, Jaime Nobbs, says the best sun cream is the one you will actually use!
You might have a preference based on the smell, texture, ingredients or price, it doesn’t matter as long as you apply the correct amount of broad spectrum SPF 30+ every two hours.

See our video ‘Staying Safe in the Sun’ below for more information.

How much sun cream should I apply?

Our sun safety ambassador also recommends a shot glass full for your entire body or a teaspoon per body part i.e arms, legs, trunk and face.

Is sunscreen harmful?

Unfortunately, there is currently a significant amount of misinformation circulating on social media regarding sunscreen causing cancer or posing harm. There is absolutely NO scientific evidence to support these claims in people and billions have safely use suncreams over the years.[1] There is actually a substantial body of well-established research demonstrating the effectiveness of sunscreen in preventing skin cancers. Nearly 9 in 10 melanomas are preventable by being UV safe by wearing a broad spectrum sunscreen as well as covering up, seeking shade and avoiding sunbeds. It has been suggested that children build up a tolerance to the sun, however, any sunburn and even tanning is due to skin damage and this can build up over time. Children’s skin is particularly vulnerable and should be protected. A ‘base tan’ does NOT protect your skin.

One serious sunburn in childhood or adolescence more than doubles their risk of developing melanomas.

We are actively working to address this issue, though we recognise that it is a considerable challenge to tackle alone with the rise of people consuming lots of information on social media.

Does sun cream go out of date?

Yes it does!

Look out for this symbol found on the back of your sun cream bottles. This will tell you how long it can be used after opening it. For example, this bottle can be used for up to 12 months after opening it. Please also note that additional factors such as storing your sun cream at high temperatures or in sun light will decrease its shelf life. Expired sunscreen will unlikely provide effective protection.

Once daily sun creams:

We recommend that you do not use sun creams that claims to only need one daily application e.g ‘once a day sun cream’. These types of sun creams have been tested in controlled laboratory conditions, using more sunscreen than the typical person would use where certain factors that effect sun protection such as swimming, exercising and sweating have not been taken into account. Notably, in Australia sun cream manufacturers are not allowed to make ‘once a day’ claims and their restricted sun safety rules means that they cannot sell products that do not promote the reapplication of sun cream. Similarly, once daily sun creams should not be used on children attending school in order to avoid reapplication.

Can I use sun cream on a tanning bed?

In the same way sun cream protects you from harmful UVA and UVB rays omitted by the sun, it would also protect you from some of the harmful UV rays emitted by a sunbed. For this reason, sunbed users don’t wear sun cream, as it would prevent tanning. This contributes to making sunbeds a major cause of melanoma and we strongly advise against their use.

Melanoma Focus advises against the use of sunbeds by the general public. Find out more about sunbeds and melanoma.

Tips for applying sunscreen

  • Apply sunscreen liberally to exposed sites 15 to 30 minutes before going out into the sun.
  • Apply your makeup and then use a spray sunscreen over the top and re-apply this every 2 hours.
  • Don’t rub the sunscreen into your skin but spread the sunscreen as uniformly as possible over the surface of the skin and allow to dry.
  • Re-apply every 2 hours or after an activity that could remove sun cream, such as swimming or excessive sweating.

Watch Jaime’s video ‘Staying safe in the sun’

Remember! Sun cream is just one sun safety tool. We also recommend:

  • Seek shade
  • Avoid the midday sun (between 11am to 3pm)
  • Wear a wide-brimmed hat and protect the skin with clothing
  • Protect your eyes with UV protected sunglasses

Sun cream for babies and children

Protecting children from the sun helps prevent melanoma later in life. Ideally, babies and young children should stay in the shade, and wear loose, cool clothing when it is hot.

Babies under 6 months:

Newborn babies have very delicate skin and the NHS recommends they should be kept out of direct sunlight until they are at least 6 months old.

Babies over 6 months and children:

You can buy sun creams specifically made for children. These tend to be higher factor and fragrance free, to avoid irritating their delicate skin. You can also find sun creams designed to make application on wriggly children a little easier, such as roll-ons, sprays and brightly coloured lotions to make it easier to see if you’ve missed a spot.

Tips for Application:

We know that applying sun cream to young children can be a tricky task, here are some useful tips to help this process:

Make it fun & distract them: Draw patterns, letters or their name on their skin and ask them to guess what it is before getting them to rub the sun cream in. You could also sing a song with them, listen to music or watch the television whilst applying the sun cream.

Sun safety and clothing:

UPF stands for Ultraviolet Protection Factor, it measures how much UV radiation goes through clothing fabric and reaches your skin. It measures both UVA and UVB. It is true that most everyday clothing can block the sun’s harmful UV rays however this is not always the case.

We recommend loose fitting, dense close-weave fabrics that when you hold up to the sun do not allow the sunlight through. Darker coloured clothing absorb more UV and provide more adequate protection in comparison to lighter shades. Clothes with more coverage are preferable e.g tops with sleeves to cover shoulders and arms and a high collar to protect neck, long skirts or trousers to protect legs. It is important to bear in mind that if your clothing gets wet it will decrease in protection as this tends to cause transparency. Please note that you still need to apply sunscreen all over before going out and this needs to be regularly applied to exposed areas of skin.

Some clothing brands make UPF clothing, we understand that some people prefer to purchase UPF clothing to ease anxiety, feel more confident in the sun or particularly when taking part in outdoors sports which require long periods of time outside. To check if your clothing is classed as UPF you can look on the label for a UPF 30/50+ symbol. There are a huge variety of brands that make UPF clothing and whilst we cannot recommend all, we have collated a small list from feedback that we have received from professionals and patients:
