The Handiest Sunscreen Ever?

I was more than a little sceptical about Riemann’s P20 and their claims that it was water resistant even after repeated swimming sessions. Riemann say that P20 offers up to 10 hours protection from the sun’s rays, and I quote, “even after frequent swimming”. The FAQs on their website also say that the product is effective after showering, so long as you haven’t used soap or “loofahed vigorously”. (God, I love the sound of that phrase. “Loofahed vigorously”. Wonderful.)

“Utter Tosh!” I said to Mr AMR, “there’s no way that this will stay on after swimming!” But it did. I stand corrected. It stayed on through swimming – repeated swimming sessions, in fact. The stuff is epic! It’s also really, really easy to apply and rub in, though some might find the smell a bit chemically. OK, everyone with a nose will find the smell a bit chemically. But I think that it’s well worth the few seconds of unpleasantness to gain a whole day’s worth of sun protection. If you’re the kind of person who forgets to reapply, or simply can’t be bothered, or who falls asleep in the afternoon only to find that they are no longer in the shade of the brolly, but frying alive in the direct heat; this is for you.

P20 provides protection from both UVA (ageing, cancer-causing) rays and UVB (tanning) rays, which is so important. You MUST make sure that your holiday sun products protect against UVA as well as UVB. Riemann’s sunscreen stood up to 38 degree heat in Greece and a 200ml bottle lasted both of us for four-and-a-half days. This will definitely be a holiday staple for me from now on!

The P20 Once-a-Day SPF20 costs from £12.95 with free delivery at FeelUnique.com.


  1. I love this stuff! Their factor 50 is a staple of my summer :) Doesn’t feel too sticky and leaves a subtle shine that it quite nice really when out in the sun.

  2. I have used P20 on my children from being 4, need to ensure you cover well and let it dry in and not go in the sunlight for an hour. But I can honestly say they never burnt or had any reaction to it, I did not have to worry all day and they were in and out of the pool all day. My youngest has just turned 18 and still insists on using it on holiday, she still comes home with a beautiful tan and doesn’t burn!

    What SPF do you use for your face if you’re acne prone? Would love to know xxx

  4. I am looking to go on holiday next summer and have heard and seen how well p20 works on friends on holiday not burning and going a fantastic colour!! I’m just a bit concerned as my boyfriend is very fair and burns easily is there a higher factor of the p20 range or what would you recommend! Hope you can help??

  5. Hi Ruth,

    Great review, I will have it on my list for when we finally use up some of the 20-odd bottles of cream we have (OH to lazy to look to see what we have and just buys a new bottle!). Anyway, when I was in Thailand a few years ago I really burned my scalp. I should have been wearing I hat, I know, but do you know of any products that spray onto the scalp as a sunblock?
