I'm saving this for the summer time so I haven't tried it but I can just say for now that the idea is excellent since it is advisable for us to reapply sun protection often during the day. It seems practical and essential to me for those who wear make-up and otherwise it's impossible to reapply sun protection. I can't review yet if the actual product works as it claims, if the powder is fine, wether it indeed protects from sunburn or it works complementary to other sun protection, but as I said the purpose of it is so important and I'm glad that it exists. Also the overall feeling of the packaging as well as the brush on the hand, seem to to be of a good quality.
