FAQs

What is the difference between P20 SPF 10 and P20 SPF 20?
P20 SPF 10 excludes 90% of the sun's burning ray. P20 SPF 20 excludes 95%. A sun protection product with a SPF of 50 excludes 98%, demonstrating that the additional protection of higher SPF is marginal.

Does P20 contain both UVA and UVB filters?
Yes, P20 contains both UVA and UVB Protection/filters.

Is P20 still effective after a shower?
P20 is still effective after a shower providing you have not used soap, a loofah or towelled vigorously.

Should P20 be re-applied after swimming?
There is no need for P20 to be re-applied after swimming unless you have towelled vigorously.

How should I apply P20?
Apply in the shade, 15 minutes before you go into the sun, to clean and dry skin. Apply generously (2mg per cm2) paying particular attention to the vulnerable parts of the body such as your nose, ears, scalp, shoulders, chest and feet.

Can I use P20 under make-up and moisturising crème?
Yes. Allow 15 minutes after applying before using make- up and crème as per your usual routine.

Can I use P20 if I am pregnant?
All ingredients in both products have been approved as cosmetic ingredients and contain no preservatives, colourants and perfume, making them safe to use on human skin, even when you are pregnant.

Washing instructions
Many sun protection products can stain fabrics, and this also applies to P20. However, we have found that by following the washing instructions outlined below, these stains can be removed. Treat the stains with a commercial stain remover (we recommend Vanish Oxi Action) and wash the fabric with an ordinary detergent. Follow the instructions closely for both products as well as the washing instructions for the fabric itself. Repeat the treatment if necessary. Avoid any use of chlorine as this may worsen the stains. To achieve the best results, fabric should be treated as soon as possible after staining occurs.
Sunburn was a severe risk and would have been catastrophic. But with P20 we did not suffer sunburn at all throughout the two- month journey. The apply once and forget style of P20 seemed too good to be true but it performed perfectly. P20 meant that we could consider the daily task of sun protection as done and get on with rowing across the ocean.
