4HR Water Resistant offers the same physical protection from damaging UV rays as the original award winning INVISIBLE ZINC®, but with 4 hours water resistance. With a non greasy formula and transparent finish, it's ideal for outdoor training, the beach or a day out on the boat. The difference is in the micronised 100% natural mineral reflectors which create an invisible waterproof shield protecting from both UVB and deeper penetrating UVA rays. NO titanium dioxide or chemical fliters. Suitable for sensitive skin and children.
PLEASE NOTE 50 ml size is now 50+ spf.
