What does increased SPF mean? The term SPF is on the front label of every sunscreen lotion. SPF stands for sun protection factor, but it really measures how likely an angler is to get sunburnt. Using an SPF 15 sunscreen means it will take 15 times longer for skin to begin to burn than it would without sunscreen, says Australian Gold sunscreens. The Australian Gold Botanical Sunscreen features 50 SPF protection, designed free of Oxybenzone, Paraben, Phthalate, PABA, petrolatum, sulfate, dye and oil. This environmentally friendly option should be reapplied after about an hour. The mineral sunscreen has strong UVA/UVB broad spectrum protection and is also safe for babies at least 12 months old.
