What’s the difference between UVA and UVB?
UVB radiation – referred to as “shorter rays” – is the usual suspect behind same-day sunburns due to overexposure. UVA radiation – called “longer rays” – is responsible for long-term skin damage due to sun exposure with some contribution to sunburn. UVA rays are responsible for some 95 per cent of the radiation that reaches our skin, while UVB only accounts for five per cent. This doesn’t mean that we should ignore UVB – even that five per cent can be dangerous. But it does mean that we should definitely pay attention to UVA protection, especially since UVA rays are not absorbed by the atmosphere and can affect us year-round, in the shade, and through haze, fog and certain types of glass.
SPF - only a part of the equation
Kateline Turgeon, director of national training at La Roche-Posay and Vichy, says, “The main difference between these new regulations and the current ones is that products were able to claim UVA protection if they had one ingredient that was proven to protect against it; there was no minimum level of protection required.”
ooking for a sunscreen that offers UVA protection in accordance with the latest regulations? Select sun care products, such as La Roche-Posay, feature the new UVA logo and are already available.
Leading the way in UVA protection
“Our products have such a high level of UVA protection that it was easy for Health Canada to approve our use of the new UVA logo,” says Kateline Turgeon. “We also had all the clinical results in place to show the necessary specifics about the formulas and prove that we had the necessary UVA protection.”
As a result, La Roche-Posay’s sun care products were among the first few Canadian products to feature the new UVA logo. Currently, only 20 per cent of all sunscreen products on the market can make the same proven claims of proper UVA protection.
