Is factor 50 better than factor 30?

Factor 50+ filters around 98% of UVB versus about 97% for factor 30. The margin matters most for fair skin, strong sun and long days out — especially since most people apply less than they should.

Can you still tan with factor 50?

Yes, slowly — around 2% of UVB still reaches the skin, so you tan gradually while being protected from burning.

Do I really not need to reapply?

One generous morning application protects for up to 10 hours. Still top up after hard towelling or very long periods in water — water resistant isn't towel-proof.

Is it OK for children?

Factor 50+ is the right band for children's skin — P20 also makes a dedicated Kids SPF 50+ cream. Babies under 6 months should be kept out of direct sun rather than protected with cream.

Does P20 stain clothes?

It can while wet — let it dry for around 15 minutes before dressing.

Product overview

About Riemann P20 Once a Day Sun Protection SPF 50+

P20 SPF 50+ pairs the highest everyday protection band — factor 50+ filters around 98% of UVB — with P20's once a day formula: one generous morning application protects for up to 10 hours. It's the pick for fair or sun-sensitive skin, strong tropical sun, and anyone who'd rather not gamble on remembering to reapply. 200ml spray.

Factor 50 sun cream, once a day

Most factor 50 sun cream needs reapplying every 2 hours — the step most people skip. P20's photostable formula absorbs into the upper skin layer and holds its protection through the day instead of breaking down in sunlight, closing the gap between the protection on the label and the protection you actually get.

How to apply

Spray generously onto clean, dry skin, spread evenly, 15 minutes before sun exposure — around six teaspoons for an adult body — and let it dry fully before dressing, as P20 can mark fabrics while wet. Very water resistant, but top up after hard towelling or hours in the sea.
