Is there a difference between sunblock and sunscreen?
Technically yes, however labeling and common usage tend to use the two terms interchangeably. However there a difference. Both sunblock and sunscreen will protect your skin from UVA and UVB light (aging rays and burning rays), they use different chemicals and those chemicals work in different ways, which is why different terms are used. Sunblock works like a mirrored shield. It contains minute particles of reflective material. They reflect the sun’s rays away from your skin blocking the damaging rays from ever reaching at all. The ingredients included in sunblocks include Titanium dioxide and zinc oxide.
A sunscreen works in a way more like a sponge: where the sunblock reflects the beams away from your skin, the sunscreen soaks them up before they can reach you. Those rays that escape have been altered in wavelength, so that they are no longer in frequencies that endanger the skin.
Does the Difference Between Sunblock and Sunscreen make one better than the other? Not at all, it is a personal preference. Many of the newer formulations contain both sunblocking and sunscreeining ingredients. The most important things is the SPF number – it indicates the strength of the product.
