Medscape (5/19, Doheny) reported, “About a third of sunscreens tested by experts…provide less than half the SPF protection claimed on the label,” according to Consumer Reports’ annual sunscreen report. According to the article, the Food and Drug Administration does not routinely test sunscreen products’ SPF.
Dr. Bader recommends sunscreens that have a high concentration of zinc oxide and/or titanium dioxide as the active ingredient(s). These are physical blockers, that reflect all of the suns rays (UVB and UVA).
Chemical blockers only work for specific wavelengths and break down, often within a few hours of sun exposure.
According to a recent study, a single dose of at least 100,000 IU vitamin D3 rapidly attenuates sunburn when given within one hour of sun exposure. Lower doses were far less effective.
The DigniCap Cooling System was FDA approved in 2015 to prevent hair loss, which may be of benefit to those undergoing chemotherapy. The FDA has just approved a second system, the Paxman Scalp Cooling System, for reducing hair loss in breast cancer patients undergoing chemotherapy.
A recent meta-analysis and data from the 2013 Youth Risk Behavior Survey concluded that prohibiting tanning bed use for minors could potentially reduce the incidence of melanoma by 4.9% and the number of melanoma deaths by 4.7%.
It has been long known that tanning bed use increases the risk of cancer, but these findings are quite alarming. A number of States have already made changes that prohibit minors from using tanning beds. Hopefully, other States follow suit.
