WEDNESDAY, July 25, 2018 (HealthDay News) – Many people apply sunscreen too thin, and that could mean much less sunscreen than they had hoped for, new research shows.
So it could be a good idea Englisch: www.moviesfilmonline.com / en / movies / … of – the – moon. […] Sunscreens with a higher sun protection factor (SPF), the British researchers said to.
"Research shows that the way sunscreen is applied plays an important role," study author Antony Young of King's College London
In his study, Young's team investigated DNA damage to skin samples from 16 fair-skinned people using different amounts of sunscreen. The skin samples were exposed to ultraviolet (UV) light, similar to that occurring during a day in the sun or during a long beach vacation.
The study showed that typical amounts of sunscreen are used by humans ̵
Research showed that even in thinner applications sunscreens prevented at least some UV from damaging the exposed skin. However, this level of protection increased as the amount of sunscreen applied reached the levels recommended by the manufacturer.
"However, since most people do not use sunscreen as tested by manufacturers, it is better for people to use a much higher sun protection factor is necessary," said Young in a university press release.
A US dermatologist said the findings are consistent with the advice he gives to his patients.
"Dermatologists usually tell patients that they should use SPF 30 sunscreens and more, because if they use an SPF 15 while on vacation, they probably only get one-third to one-half the SPF protection, as indicated on the label "said Dr. Scott Flugman. He is a dermatologist at the Huntington Hospital of Northwell Health, Huntington, New York.
But even though it is thinner than recommended, sunscreen with a high sun protection factor provides "significant protection against DNA damage, although this sunscreen dose protects much less than the heavier applications." "He said."
Dr. Michele Green practices dermatology at Lenox Hill Hospital in New York City, and recommends that people use "sunscreen" outdoors every two hours, and that if you are fair-skinned and have a predisposition for skin cancer, have SPF 50+ and wear protective clothing. "
Clothing can be a key factor, she has added. "There is an abundance of sunscreen clothing on the market that provides extra protection against the harmful rays of the sun," said Green. "It also helps, as most people just apply sunscreen on their face and do not spend the time to apply to their body as well."
The study was published on July 25 in the journal Acta DV . 19659002]
