Riemann P20 Once-A-Day Sun Protection SPF 10 Low is non-greasy, non-oily & fragrance free to provide the ultimate coverage, both in & out of the water, for up to 10 hours a day *. Once-a-day application: P20 is designed to ensure one application a day is sufficient, keeping the time spent reapplying sun protection to a minimum. Once-a-day application means a little goes a long way, making P20 more economical than other sun preparations that need to be re-applied regularly during the day. Superior water resistance: Riemann P20 Once-A-Day Sun Protection SPF 10 Low is proven to remain effective even after frequent swimming. In fact, P20 has been categorised as ' Very Water Resistant', the highest classification available from Colipa Guidelines for Evaluating Sun Product Water Resistance**. UVA & UVB Protection: Offering UVA & UVB protection through highly photostable filters, P20 retains its effectiveness even on extended exposure to the sun. Easy to use: The unique, easy-to-use formulation has a thin consistency, ensuring an even & economic coverage that absorbs rapidly. Stay safe in the sun: Riemann P20 Once-A-Day Sun Protection SPF 10 Low with a SPF*** of 10, absorbs 90% of the sun's UVB (burning) rays, & offers 10 hours of protection with a single application whilst still allowing you to build a tan. * An independent laboratory test using human volunteers proved that P20 provides 10 hours of sun protection. ** Learn more about the water resistance testing standards on www.colipa.eu. *** SPF indicates how much longer a person can be in the sun without being burnt if he/she wears sun protection, as compared to unprotected skin. Directions for use: As Riemann P20 Once-A-Day Sun Protection SPF 10 Low is non-oily, non-greasy & fragrance free (once dry), there is no grease or "shine" as with normal sun preparations so both can be used under make-up & moisturising cream. It is ideal for men & women with fine or thinning hair as it protects the scalp. Just apply 15 minutes before going out into the sun or swimming, to allow a protective film to form on the skin. Apply generously in an even layer, paying particular attention to the vulnerable parts of the body such as nose, ears, scalp, shoulders, chest & feet. For first time users, or for those with fair & sensitive skin, Riemann recommend repeating the application 10 minutes after the first application to ensure that the product is applied adequately & evenly to the skin. This will provide the best possible protection. Full directions must be read carefully before use.
