Sun Sense

Riemann products are developed scientifically and tested independently. We have specialist knowledge of how the sun affects our skin, ultra violet radiation and the way skin varies from one person to another.

UVA and UVB

Found in sunlight, ultraviolet (UV) radiation is invisible to the human eye. There are three types of UV radiation:

  • UVC

    UVC is absorbed into space by the atmosphere and does not reach the Earth's surface.

  • UVB

    UVB is responsible for the majority of sunburn and plays a key role in developing skin cancer. Traditionally sun protection products have mainly protected us against UVB rays.

  • UVA

    UVA mainly damages the structure of the skin and causes wrinkles, sagging and premature ageing of the skin. UVA penetrates deeper into the skin than the UVB and, like UVB, is known to cause cancer by damaging the DNA of skin cells.

  • Why should we protect ourselves against both UVB and UVA?

    Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon. About 90% of non-melanoma skin cancers are associated with exposure to ultraviolet (UV) radiation from the sun.

    UVA was thought not to cause any skin damage as there are no visible short-term signs of this radiation. However, it has now been shown that UVA can contribute to skin cancer. We are exposed to UVA rays during the daylight hours throughout the year as they are not blocked by clouds or windows. That is why it's important to find a sun protection product that protects against UVA as well as UVB.

  • What is photostability?

    To protect the skin, sunscreens use UV filters that absorb radiation from the sun. When a sunscreen is exposed to this radiation, it can alter the chemical structure of the UV filters and reduce their protective capabilities.

    A "photostable" sunscreen is able to withstand the effects of UV exposure better, so it keeps its level of protection.

  • What does "broad spectrum" protection mean?

    Broad spectrum protection means the ability to protect against the harmful effects of both UVA (ageing rays) and UVB (burning rays). To be classified as offering broad spectrum protection, a product needs to absorb or reflect at least 90% of the UV rays from the 290 to 400 nanometres (nm) wavelength range.

  • Did you know?

    The sun's UV rays are reflected by snow, water and sand, thus exposing your skin to higher doses. Snow reflects up to 85%, sand reflects about 17% and water 10% of the sun's UV rays.

Level of spf

The Sun Protection Factor (SPF) specified on your bottle of sunscreen tells you how much protection your sunscreen offers against UVB rays and is also an indication of level of protection against erythemal UV, which also includes a bit of UVA. It is measured using a standardised test. In general, the higher the number, the greater the protection, as you can see from the chart.

Levels of protection explained
Protection category SPF
Low protection 6, 10
Medium protection 15, 20, 25
High protection 30, 50
Very high protection 50+

The SPF number indicates how many times longer you can stay in the sun before starting to burn than you would without sun protection. In other words, the higher the SPF the greater the protection. But remember these are theoretical values. In reality the time depends on other factors such as your skin photo type and the local UV intensity.

To choose the right SPF, you need to consider several factors. The most important of these is your skin's phototype, which includes the colour of your skin before exposure to the sun, your hair and eye colour and other factors. You can check your skin type on our sun advice page. You also need to think about where you are going on holiday and what time of year it is.

SPF advice for children

Children's skin is more sensitive to the sun and more prone to sun damage so we recommend choosing a higher SPF (at least SPF 30 or 50+) for kids than you would for an adult.

Sun advice

We enjoy being outdoors during the summer. The sun gives us a feeling of general wellbeing and we associate a tan with looking healthy. But to have an active outdoor life we need to be careful and follow these important guidelines:

  • Stay out of the sun between the hours of 11am and 3pm when the intensity of the sun's rays is greatest.
  • Take into account the strength of the sun and don't expose yourself to it for longer than your skin type allows.
  • Do not stay in the sun too long even when using a once a day sun protection product.
  • Never expose babies and young children to direct sunlight.
  • Do not apply P20 to broken or sun-scorched skin. If you have already been burnt, make sure you stay out of the sun.
  • Keep yourself well covered with clothing and use sunglasses.
  • Apply P20 generously and evenly. An adult will require between 30-40ml per application.

Skin type guidelines

Simply match your skin type with your location or holiday destination to find out which factors are right for you and your family.

Recommended SPF to different skin types
Skin type Moderate:
UK / N.Europe
Hot:
S.Europe / Mediterranean
Very hot:
Tropics / Africa / Florida
Fair SPF 30 SPF 30 SPF 50+
Medium SPF 15 SPF 20 SPF 30
Dark SPF 15 SPF 15 SPF 30
Children's SPF 30 SPF 50+ SPF 50+

NOTE: This is a general guideline as everyone's skin is different. You should determine your own skin's tanning ability. Use common sense and try appropriate products for brief periods of time in the sun to avoid over exposure and/or sunburn.

  • One application lasts up to 10 hours
  • Superior water resistance
  • Quick drying
  • No artificial preservatives
  • Choose between SPF 15, 20, 30 and 50+

Cookie Policy

Riemann Cookie Policy

What are cookies?

Modern websites are powered by lots of bits of computer technology, many of which involve other computers effectively 'talking' on a regular basis to your computer or mobile phone as you use the internet. Cookies are just one of these technologies.

A 'cookie' is technically a very short piece of computer code that can be loaded (or 'set') onto your computer or mobile phone when you access or do something on a web page. Once set, it can be accessed by that website, and potentially some other computers from time to time. It's not harmful to your computer or mobile phone like a virus or other malicious code.

Cookies are used for lots of different purposes. For example, they can power shopping baskets, help keep you secure, allow pre-population of forms, and enable a website provider like us to understand how their website is used. They are also used to drive online advertising that is relevant to you by building up a picture of what you are interested in from your use of the internet.

Cookies have a lifetime. Many only last until you close your browser or for a short time. These are called 'session cookies'.

Some last far longer though, for example, to enable a website to recognise you when you return to them. These are called 'persistent cookies'. Where possible, we'll let you know how long these cookies last for.

Cookies set directly by a website owner (like us) are generally known as 'first party cookies'. Many (if not most) modern websites also use bits of hidden technology provided by other parties. Online advertising is a particularly common example. These other parties may also set cookies when you use our website. If they do so, their cookies are generally known as 'third party cookies'.

There are some other computer technologies which are technically different to cookies but are used to perform very similar jobs and function in a very similar way. For example, 'locally stored objects' (or 'flash cookies') are used to power some online video content, and 'web bugs' (or 'web beacons') are used for many of the same purposes as cookies.

If you want to know more, we suggest you visit this site. Please note that we are not responsible for other party's sites.

Now that we've explained what cookies are, please read 'How do we use cookies?' to understand how we use them and similar technologies.

How do we use cookies?

We have set out brief details of the cookies and similar technologies we use below, together with an overview of why we use them.

These cookies enable Google Analytics software to work which helps us to take and analyse visitor information such as browser usage (e.g. how long you spend on our website, when you start and finish, the amount of times you visit, when your previous visit was), new visitors' response to marketing and shopping times. This information enables us to produce reports to help us improve our website, the shopping experience and to make our marketing activity more relevant. Please note, the data stored by these cookies can only be seen by us and Google.

*See 'What are cookies?' for what these terms mean.

Vimeo Where we embed Vimeo videos on our website, we use cookies to capture and analyse visitor information related to video usage such as views and shares.

Social media. We love it when you share information from our website through a social media network such as Facebook or Twitter, but when you do so, please be aware that your social network may set additional cookies and similar technologies on your computer, mobile phone or tablet device. We're not responsible for these other cookies and technologies. Please check the privacy and cookie policies of the social media networks you use for full details of what they do.

We regularly review the cookies we and our suppliers use to keep them to the minimum we think we need. In doing so, we aim to respect your right to privacy in your online life, which is very important to us, but also ensure you have a good browsing experience and ensure we have enough of, and the right kind of information to improve our website and business.

In case you do not agree with our policy, we have provided details of how you can manage cookies yourself (See 'How can you manage cookies?'). By following the instructions set out, you can tailor how your web browser behaves to ensure only cookies and similar technologies with which you are happy are loaded onto your computer, mobile phone or tablet device.

How can you manage cookies?

Some providers of third party cookies give you the means to opt-out of the services they provide (for example, targeted advertising). Where we are aware of our suppliers doing so, we have provided details in the 'How do we use cookies?' section. These providers may use cookies to power their opt-out service, so if you choose to block cookies using the means set out below, their opt-out service may cease to work and the adverts you sought to block may reappear.

The main way to manage all cookies and similar technologies that are set on your computer, mobile phone or tablet device is through adjusting your web browser settings. In practice, this process will result in some or all of them being blocked.

You'll need to consult your browser's user guide to see how you can use it to restrict or block cookies and similar technologies. Some browsers are more sophisticated than others in managing these technologies, so if you want greater controls, it would be worth comparing a few of them.

What will happen if you choose to restrict or block cookies?

If you choose to restrict or block cookies and similar technologies on your computer mobile phone, and/or tablet device your browsing experience is likely to change.

The extent of the changes will differ from website to website, depending on how they use cookies and similar technologies. Some websites may be completely unaffected, but you may see significant changes to others. Your browsing experience may become less interactive, less personal to you, contain more error messages, and certain websites may not work at all, or at least not as you have come to expect. For example, you may see fewer adverts, but you may not be able to make online purchases because website shopping baskets are normally powered by cookies.

Our website is designed to use cookies, so it may be affected by some or all of the issues set out above, as well as others not listed here. In particular, your shopping experience on our website will be limited to browsing and research, and you won't be able to add products to your shopping list / basket or buy them.

Updates to this cookie policy

We review our use of cookies and similar technologies regularly (see the 'How do we use cookies?' section for full details).

In doing so, we may change the cookies and other technologies we use and how we use them.

As a result, we will need to change this policy from time to time to keep it accurate and up to date.

If we change this policy, we will tell you when you next visit our website, and give you a link to our revised policy. That way you can check to see if you are happy with our new policy and adjust your browser settings if you want to before proceeding any further.

Please look out for these notices in future when you are using our website.
