When you’re tanning on the beach, you may want to think twice about sunscreen, a research study has found.
In a study published in the International Journal of Preventive Medicine, researchers analysed the efficacy of sunscreen in the sun.
They also found that the sun may increase the risk of sunburn, especially among young adults.
“I think it’s important to look at the long-term effects and how they may impact your health,” said study author and professor of dermatology at the University of Queensland Dr Tessa Lomas.
“It may be that it increases your risk of developing skin cancer.”
People are not going to get cancer if they don’t take proper care of their skin.
“Dr Lomas said the study was the first to show that sunscreen could potentially increase the risks of sun burn.”
It’s been known for a while that the longer you use sunscreen, the more you’ll burn,” she said.”
If you’re using sunscreen longer, the longer it will stay on your skin and it will have more UV exposure.
“There’s a potential for the longer-term consequences, which we’re not sure yet.”
Dr Lamas said there were some key questions that needed to be answered about sunscreen’s effects on skin.
“What is the concentration of sunscreen, and what is the level of protection that it provides?” she said.
“Is it good for you?
Are you getting the best results?
We need to understand these questions to really understand what we’re doing to protect ourselves against the sun.”
Dr Gwen Williams, a dermatologist and researcher at the National Centre for the Study of Dermatology at Sydney University, said the research was intriguing.
“We know that sunscreens are very effective at protecting people from the sun,” she explained.
“They reduce the risk to skin by 20 per cent, but the mechanism of that effect is still unknown.”
This is something that’s not completely understood.
“What does the study show?
Dr Williams said that the results suggested that a sunscreen that contained about 1 per cent zinc oxide and 0.7 per cent titanium dioxide could protect against the effects of the sun’s UV rays.
She said this was a more protective sunscreen, but it wasn’t perfect.”
The zinc oxide is a little bit stronger than the titanium dioxide and it may protect against some of the UV damage, but not all of it,” she added.”
These results are not as strong as those of other sunscopes, but we know from past studies that there’s some protection in that sunscreen.
“What are the options?
Dr Loma said there was a range of options for sunscreen.”
You could try to use a sunscreen with a lower concentration of zinc oxide, but that could be problematic.
“Because zinc oxide has a stronger effect, you can have more zinc oxide on the sunscreen than titanium dioxide, which could lead to a higher concentration of the zinc oxide,” she told AAP.
“But zinc oxide can also damage your skin.
So it’s more important to use an adequate amount of zinc.”
Dr Williams also suggested a sunscreen containing about 2 per cent emollients, which were made from ingredients such as emollient, mineral and mineral-rich emollent, as well as sunscents that were also effective at absorbing UV rays, such as zinc oxide.
Dr Lomsa said she wanted to encourage people to use sunscreen that was safe for the skin and minimising its impact on skin health.
“So you have to use sunscapes that are safe for you, minimising the amount of sunscreen you’re putting on your body,” she noted.
“Then there’s the possibility of using a sunscreen formulated with titanium dioxide which is better for the environment.
So we’ve got to be careful when it comes to these two types of sunscreen.”
Dr Dwayne Loman, a cosmetic dermatologist at the Sydney Medical School, said that, while the results were promising, sunscreen wasn’t the only way to prevent sunburn.
“Even with sunscreen, there’s a risk of burning,” he said.
“But the more sunscreen you put on, the less likely it is that you’ll get sunburn.”
