Product overview
About Riemann P20 SPF 30 — 100ml travel size
This is the travel size sun cream version of P20's once a day classic — the same up-to-10-hours factor 30 protection in a 100ml bottle that's allowed in airline hand luggage. One morning application covers you for the day's sightseeing, and the bottle takes up almost no space in a daypack or cabin bag.
Travel-friendly by design
At exactly 100ml it meets the cabin liquid limit, so it can fly in your hand luggage — no decanting, no surrendering it at security. Because P20 is once a day, a 100ml bottle goes further than it would with a reapply-every-2-hours sun cream: roughly 8–10 full-body adult applications, or a week of face-neck-and-arms city breaks.
How to apply
Apply generously to clean, dry skin 15 minutes before going out and let it dry fully before dressing — P20 can mark fabrics while wet. Factor 30 filters around 97% of UVB, and the very water resistant formula holds up through pools and sea swims, though you should top up after hard towelling.
Good to know
Photostable, non-greasy and dries clear. No sun cream gives 100% protection — use shade and cover up in the hottest hours.

Frequently asked questions
Can I take this sun cream in hand luggage?
Yes — at 100ml it meets the standard airline cabin liquid limit, so it can go through security in your liquids bag. That's the point of this size.
How long does a 100ml bottle last?
Because P20 is applied once a day rather than every 2 hours, 100ml stretches further — roughly 8–10 generous full-body applications, or a week-plus of face, neck and arms on a city break.
Is it the same formula as the big bottle?
Yes — identical once a day, up-to-10-hours factor 30 formula as the 200ml, just in a cabin-compliant bottle.
Does P20 stain clothes?
It can while wet. Let it dry for around 15 minutes before dressing, especially before putting on holiday whites.
