P20 activities

About P20

P20's unique formula is non-greasy and fragrance free to provide the ultimate coverage, for up to 10 hours a day1  and is very water resistant2.

  • 10 hours sun protection


    P20 is designed to ensure that one application a day is sufficient, keeping the time spent applying and re-applying sun protection to an absolute minimum. P20 is proven to work for up to 10 hours1 due to a very stable formulation.

  • Superior water resistance


    P20 is proven to remain effective in the water, even after frequent swimming. P20 is Very Water Resistant2 and ranks in the highest class of Cosmetic Europe's water resistance classification system.

  • UVA and UVB protection


    P20 offers broad spectrum photostable UV protection covering both UVA and UVB rays and retains its effectiveness even after and during exposure to the sun. P20 is proven to work for up to 10 hours in the sun.

  • Ease of use


    P20's lightweight consistency ensures an even coverage. Once a day application means a little goes a long way, making P20 more economical than other sun care products that need to be re-applied regularly during the day. P20 is absorbed rapidly leaving a non-greasy skin, so there are none of the messy white streaks common with cream-based products.

P20 Heritage

Riemann A/S is a Danish manufacturer of specialised skin care products. It was founded by Claus Riemann who had the vision of creating products with an "objectively identifiable effect" - that people can experience themselves. In other words: products that work. This simple yet challenging ambition is still our vision today.

The story began in Claus Riemann's family house in the seventies. He had already seen the need for reliable sun protection and launched P20 sun protection in 1979. The very first high factor sun protection on the market, it offered the extra benefit of needing only one application a day. Hence P20 "10 HOURS SUN PROTECTION".

Today, P20 is the 4th largest branded sun protection brand on the market, by £ value3

P20 should be compulsory for all desert runners. It certainly looked after me.

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.

If you want any further information about our approach to cookies and similar technologies, our websites in general or have any other privacy questions relating to us, we'd be happy to help you. Our contact details are set out here.
