I already have the factor 30 so I bought the factor 50 to try for more protection. Its a very good protector against the sun. It sinks into the skin and does not mark clothes. When applying the factor 50 put it on carefully so you are not trying to apply a mass of cream in one go. You can always put on a second layer if needed. I would recommend it.
I have extremely sensitive skin as have my grand children. This is the best sun cream that we have ever used. My great grand niece has eczema and this is the only suncream that hasn’t affected her. I highly recommend it.
