The Difference between Natural Sunscreens and Chemical Sunscreens
One complaint some people have of natural sunscreens is the film of white they can leave over your skin – a great way of seeing the spots you missed when applying but not great for the beach babe look.
But why can’t natural sunscreens get away without any film of white altogether? What is the difference between natural sunscreen alternatives and their chemical counterparts?
Chemical sunscreens work by absorbing UV rays before they can do damage. Usually, single chemical ingredients protect against either UVA or UVB, not both, so for broad-spectrum protection, you need to choose a chemical sunscreen containing multiple chemicals. Chemical sunscreens are absorbed into the skin, and are more likely to cause irritations, allergies or other health concerns, and can degrade over time.
Most natural sunscreens work by forming a physical barrier and use opaque minerals to form a layer on top of the skin that reflects or scatters UV light. These sunscreens contain either zinc oxide or titanium dioxide as the active ingredient and can offer effective broad-spectrum protection against UVA and UVB rays.
