Riemann P20 Once a Day 10 Hours Protection SPF 20 Medium 200ml

great product. I love the outdoors but I get easily burnt by the sun-- even the sun's reflections on snow. I used this product while gallivanting in the hot and humid Mexico for about 2 weeks -- Applied this on exposed skin (including face) in the morning and that's all that was needed-- NO sunburn, no grease, no soreness, no skin peeling one week after coming back from vacation. As indicated, it will, at the least, give your skin a light golden tan. It is waterproof -- no need to re-apply even after we did water activities. A friend shared this bottle with me and after 2 weeks -- there's some about 1/4 left in the bottle. it would smell like "a light cooking oil" at first, but the smell dissipates and you just forget about it. Awesome product-- first one that really worked for us. Product MAY also be available at Pro Bass Shops or check out your neighboring camping shops IG. REI, Dicks sporting goods. But i'm getting my next one from here since I already have a shopping cart going ! ENJOY!!!

I have been using P20 since I was a child, when I can only buy it when in Europe. I am a very pale skinned person and I can wear this all day in the Caribbean sun and not get burnt. For people that tan, you will tan through this sunscreen, but not burn. If I am in the water for a long period of time, I will reapply - but otherwise I would not. The sunscreen looks and has the feeling of an oil and can turn whites a bit yellow - so I would recommend not wearing white while using this product. Nothing works as well as this one - I have tried very high end brands of other sun screens that do not provide the same protection. Don't hesitate - try it out now!

This works exactly as it is marketed to. I wore this at burning man (if you don't know what that is than suffice to say I wore it camping in the summer in the desert) and let me just say there were parts of my body that don't frequently see sun covered with one go of this first thing in the morning and I was good all day. I was riding bikes and getting really sweaty and it was perfect. I didn't burn at all. Perfect SPF 20 protection. I'm pale and burn when I don't have anything on. It feels a bit oily when you put it on but then it soaks in really really fast (like the way alcohol feels when you put in on your skin, thick and wet at first then it just soaks in and evaporates). Doesn't really leave you feeling as gross or as sticky as cream sun block.

This product contains ingredients that are banned in some places. Repeated studies show destruction of reefs. I bought 2 for vacation and now I regret it. It’s not returnable. I’ll just use it when I’m not going to the ocean. It works well. It does stain fabric yellow until it dries, though.

Although it takes a bit to dry, this is the most effective sun screen I have ever tried. I am a fair fragile flower and I went on a trip to Isreal and southern California in July and did not get burned or even pink. This stuff is great! You do need to be careful of staining...avoid white and use an oxi product to get stains out of fabric. (I did not have much staining, as I let it dry before putting one clothing.)

I bought this for a trip to Norway and wanted to make sure we were fully covered and did not have to worry about re-applying. I was a little surprised when I received it, it was not sealed (meaning when I took the application top off it had nothing sealing it closed) and the bottle was 1/4th empty. That was surprising I would think it would be completely full and have a seal but since I've never bought this product before I have no idea what a FULL bottle feels like ? It's expensive so I am hoping I did not get 3/4ths of someone's used bottle. Its very very think liquid so I am again hoping I did not get a old 3/4ths empty bottle. It does smell like chemicals because it's made of chemicals but that smell goes away after a short while. It takes a little time to dry but goes on pretty easily. I will see how I do in Norway but so far not so bad in Florida sun.

I originally bought this product when I was going on a class trip to Turkey for a month. I'm very fair skinned and I wanted a product I could put on in the morning and not have to carry around with me for the rest of the day for fear that it would wear off. P20 worked perfectly for me! I of course ended up with a tan since it does let some rays through, but it got me through all sorts of situations including sun exposure at high altitudes and days of alternating wet/dry situations with high sun exposure as well. My only wish is that the product had more listings/purchase availability on amazon (or in the US in general) and that the higher protection levels came in lotion form. Although my periods of sun exposure weren't as long as some people may experience, I'm now living in a high altitude Utah desert where I often spend several hours a day in the sun. So, long story short, I'll be ordering this product again and will be sure to update this review if my opinion of this product significantly changes.

I bought this after doing some googling about my prickly heat rash that I get when out in the sun. Come to find out it is worsened by most sunscreens that can be bought on the shelf from your store of choice. They block your pores and cause the prickly heat rash to become worse!I was worried about this being only 20 SPF, but after using it a couple times I haven't been burnt and I haven't broken out! Seriously such a relief going to the beach and knowing I won't break out in a huge rash. It's quite watery and not like your typical sunscreen, but it does the job.Highly recommended to people experiencing heat rash, give it a try!
