Make no mistake, that is how to use the right sunblock!
Sunscreen does not argue that the most effective way to protect the skin against UV rays and the threat of skin cancer, especially for people who live in tropical countries where the sun is all year round. But apparently, this leads to the question: is it the right way to use your sunscreen?
Recent research published by the Journal of the American Medical Association (JAMA) shows the ingredients in sunscreen can enter the bloodstream.
In this study, safe limits from the Food and Drug Administration (FDA) are concerned. In addition, the latest study of sunscreen as a safe treatment was released four decades ago, namely in 1970.
Is it always the current condition?
Is harmful content sunblock?
This research does not always preclude the use of sunscreen. Still far. At this stage, the research team continues to investigate the contents of sunscreen to absorb the body.
The FDA research team led by Murali K. Matta, PhD, conducted a survey of 24 healthy volunteers.
Each of them was asked to use sunscreen under various brands and formulations. The number of sunscreens applied is the same: 2 mg every 1 cm 2 to 75% of the surface of the skin.
All procedures are carried out indoors without sun exposure. Age, skin type, sunscreen type are not the main objectives of this study.
This test is carried out four times a day for four days. After seven days, their blood samples were taken.
Results?
First, it was found that a high plasma concentration of avobenzone. To a lesser extent, the active compositions of oxybenzone, octorylene and ecamsule are found.
In addition, test results also showed in the first days after applying sunscreen, four times, 23 of the 24 volunteers were exposed to a composition of more than 0.5 ng / mL. This is the threshold for toxicological concern (TTC) to the FDA for carcinogenic risk.
Abortion accumulation?
the answer is yes. Sometimes, there is an accumulation of ingredients in the body.
The 0.5 ng limit / ml FDA limit is fulfilled in a short time six times since the first avobenzone, and requests octocrylene and oxybenzone two hours after application.
From these results, the researchers were asked to conduct further research to determine the clinical impact. The facts explained above do not mean that the use of sunscreen must be stopped.
Indeed, the contents of oxybenzone are blamed as the most dangerous substances when absorbed into the body through the skin.
However, the biological effects and absorption are still in further research.
The use of sunscreen is still important
Reading the results above, you don't need to panic and immediately avoid sunscreen drastically. FDA regulations for sunscreen counter discretion in 1970 and it must be an extension of the standard.
However, the use of sunscreen is very important. The main threat to the skin is ultraviolet radiation.
The most deadly type of skin cancer, melanoma, is closely related to ultraviolet exposure in different cases.
In the meantime, you can always use sunscreen calmly. Choose a sunscreen with a security composition such as zinc and titanium dioxide.
However, the benefits of using sunscreen are still far higher than haunting "threats".
Although FDA regulations regulate sunscreen to protect against the risk of skin cancer remains a top priority. Balance with a critical attitude towards sunscreen addiction.
