Overview

What is Riemann P20?
Riemann P20 SPF20 Lotion is extremely effective at protecting against sun damage, promising water resistance and 10 hours of protection. 

How does Riemann P20 SPF20 Lotion work?

Riemann P20 Lotion has a Sun Protection Factor (SPF) of 20 which refers to the amount of time you can stay in the sun without getting burned (damaged by UVB rays).

SPF20 means that it increases the time by a factor of 20, so if your skin would normally redden in 30 minutes in the sun (without any sun protection), then SPF20 will mean that you can stay in the sun for 600 minutes.

What are the benefits of taking Riemann P20 SPF20 Lotion?

Protecting yourself in the sun is important and helps to keep your skin healthy. Riemann P20 Lotion not only protects in the sun (including if you swim frequently, as it’s highly water-resistant), but it’s also fast-acting and is active 15 minutes after application.

The lotion also has a quick-drying, non-greasy formula that leaves no white marks and only needs one application per day.

How do I use Riemann P20 Lotion?

Use Riemann P20 Lotion by dispensing some product into your hand or directly on the skin and then massage in. Use a generous amount and ensure that all of the skin is covered (even those areas that will then be covered by swimwear or clothes). Pay particular attention to vulnerable areas like the ears, nose, shoulders and feet.

Allow to dry for 15 minutes before going in the sun. The lotion is water-resistant but you should pat dry after swimming, rather than rub excessively or using soap (as this will remove the product). If you do this, then ensure you reapply the lotion and wait the necessary 15 minutes before going back in the sun.

How do I buy Riemann P20 online?

You can safely buy Riemann P20 Lotion online at Cloud Pharmacy, without the need for a prescription or consultation with a medical professional, however you should adhere to the advice given in the patient leaflet enclosed.
