“Parasol is a brilliant sunscreen. But you have to follow the instructions to the letter for it to work properly. Apply it and then wait 30 minutes for it to dry before you get dressed or go out in the sun. This is the only way it works.
It is an excellent product. I've never burned when using it.
If you are in and out of the water a lot and rubbing yourself dry with a towel, it will obviously get rubbed off. If this happens, you need to top up with another sunscreen to protect your skin.”
