TY, Harry.
I use an SPF#55 on my face and the #30 for at least the first week of my vacation until I have a very good base and then I probably would drop back to an SPF#15.
The Biafine is an excellent product and it is readily available on the Dutch side of the island, too. We stay at the Towers and I was able to get it at the Maho Pharmacy, which is the closest one to us.
I have it from a good source the product can be ordered in the States on line but it's considerably more expensive than on the island.
