At All Good, we are proud to offer high performing, reef friendly sunscreen products for all lifestyles. All Goods SPF 30 sport sunscreen spray uses non-nano zinc oxide as its active ingredient, which works as a physical barrier on your skin to protect you from the sun. Non-nano zinc oxide is reef friendly, water resistant, and has broad spectrum UVA / UVB protection. We also add in botanical ingredients like calendula, aloe, organic green tea, rose hips, and antioxidant oils for repairing damaged skin. All of All Goods sunscreens meet stringent Reef Friendly criteria. This means that our sunscreens only use non-nano zinc oxide as the active sunscreen ingredient, we avoid all chemical UV absorbers, parabens, and harmful additives and we submit our products to 3rd party testing to verify zinc particle size. All Good Sport Sunscreen Spray avoids harmful propellant chemicals by using a Bag on Valve technology. This means the sunscreen can uses compressed air to keep pressure on the product, allowing it to dispense safely and smoothly. Be sure to reapply sunscreen every two hours or, if you are in water, every 80 minutes. Thanks for choosing Reef Friendly. And remember - All. Good. Makes. everything. Better!
