Choose a spray, choose a lotion, but by heavens, choose something! Legions of doctors, parents, and YouTube beauty influencers are unanimous on this point. If they sink into tissues and get absorbed into the bloodstream, that could be a problem. Such safety testing has never been done on the active ingredients in sunscreen , because those chemicals were approved decades ago, before anyone suspected they could be absorbed into the body.
The results, published in the journal JAMA , show that contrary to what sunscreen manufacturers have been saying, UV-blocking chemicals do seep into circulation.

The researchers saw the same patterns in all 24 of the volunteers they recruited—12 men and 12 women, who were randomly assigned to apply one of four commercially available sunscreens: two sprays, a lotion, and a cream. For those four days, and three days after, the researchers collected blood every few hours to be analyzed for the presence of avobenzone, oxybenzone, octocrylene, and ecamsule, 30 samples in all. They discovered that while it took only a few hours for the UV-blocking chemicals to spike over the target, for three of the four formulations, those levels remained elevated through the end of the study—three days after participants had ceased spraying and smearing.
Only the cream users saw their chemical concentrations tail off sooner. The fact that these sun-filtering molecules do penetrate into the circulatory system does not on its own mean that such ingredients are unsafe. To understand what, if any, effects such chemicals have on internal tissues will take more research. Particularly urgent is learning more about long-term exposure and how absorption rates differ in infants and children, with their larger ratio of body surface to volume.
The history of sunscreen regulation is long and contentious , but the core of the conflict boils down to the fact that the US treats sunscreen as an over-the-counter drug, and the rest of the world considers it a cosmetic. Those corporations balked, and development stalled in the US. Meanwhile, Europe added at least eight new, more advanced photoprotective filters to its sun-shielding arsenal. In an effort to end the stalemate, Congress passed the Sunscreen Innovation Act in But if they do, the FDA wants to see more tests—assessing cancer risk and harm to the reproductive and endocrine systems, standard drug safety stuff.
But the testing requirements could also end up giving Americans fewer choices, at least in the short run.
I have lost pounds and my quality of life has changed. I feel healthier and stronger. Brandon personally invests in all his clients and pushes them to the next level when he knows they are ready. I look forward to continuing my fitness journey with Brandon. Brandon has been my trainer for 3 years now.
His classes are challenging, but fun, and he keeps it interesting by changing it up. Every day brings a different sequence of weight training and cardio. I have gained muscle, toned up seeing more definition as well as having much more energy and flexibility. I like that his class size is limited and he keeps it small; it remains personal and effective that way.
Although I leave almost every class with a sore muscle I never knew I had before that workout, I look forward to my next class; it is easily one of the best parts of my day. If you want to be challenged, get into shape without losing interest and have fun too, Brandon is your guy.
Working with Brandon has been an absolute pleasure and, more notably, a challenge. Every session is unique and engaging.
