The student created an at-home testing kit to experiment with natural chemical-free sunscreens.
"I don't think it has sunk in yet and I don't think it will for a while."
Deery explained she was inspired to make the product after reading about eco-damaging chemicals found in commercial sunscreens that were making their way into UK water systems. "We needed to find a more eco-friendly solution because the store-bought kind are harming the marine life and the coral reefs, which just isn't fair,"That’s when she came up with the idea of creating natural sunscreens with UVA protection, derived from naturally-occurring oils.So, she constructed a homemade lightbox containing a UVA light torch.
“To achieve the Sun Protection Factor reflected on a bottle of sunscreen, you should use approximately two milligrams of sunscreen per square centimeter of skin. In practice, this means applying the equivalent of a shot glass of sunscreen to the exposed areas of the face and body – a nickel-sized dollop to the face alone. If you’re using a spray, apply until an even sheen appears on the skin,” says the organization’s site.
“Remember that sunscreen needs to be reapplied every two hours, or more frequently after swimming, heavy perspiration, or toweling off. Also remember, no matter how much sunscreen you apply, the SPF should be 15 or higher for adequate protection – and ideally 30 or higher for extended time spent outdoors. Be sure your sunscreen says “broad spectrum” on the label, which means the product protects against UVA and UVB rays.
