Safe Sea Sunscreen with Jellyfish Sting Protection was developed to help protect against the stinging mechansim of most Jellyfish, Sea Nettle, Sea Lice and Coral. It contains unique, patented ingredients that deactivate the stinging mechanism, leaving you safe and sound. Jellyfish and the like are becoming increasingly common both at home and abroad, but Safe Sea will help to take the sting out of any chance encounter! Safe Sea is available on its own as a protective lotion for divers and surfers, or as a sunscreen with a range of different Sun Protection Factors (SPF 15, SPF 30, SPF 30 + kids and SPF 50). Typically, one bottle contains enough lotion to allow four complete applications from head to toe, and one application is good for about 80 minutes when swimming or diving in and out of the water.
