Riemanns amazing SPF20 sunscreen needs to be appplied just once a day
- 90 minutes before exposure to the sun.
It will protect you all day long against harmful UVB rays while letting through UVA rays, allowing you to tan without burning.
Even frequent swimming will only reduce its effects by about 10% &, in addition, it is odourless, non-greasy & quickly absorbed by the skin.
Just remember not to moisturise before use as this will prevent the sunscreen from working effectively.
