Information Security-Don't sweat it
So-called clinical-strength antiperspirants …come with instructions that they be applied before bed for “maximum” protection from wetness and odor. … Even regular-strength antiperspirants work best when applied to underarms at night, experts told us. Bedtime application “really is the best way to use an antiperspirant,” says Daivd Pariser, M.D., president of the American Academy of Dermatology…
That is the July Consumer Reports, p.12. Other sources agree. Now surely experts have known this for a long time; why isn’t the word out?
When I told my wife that Consumer Reports said antiperspirants should be applied at night, she said that was just silly, and was not persuaded. And folks commenting on clinical-strength antiperspirants are often skeptical:
The product is very easy to use, but does have some strange directions that are unlike normal antiperspirant products. First, you’re supposed to apply it at night before bed … I did not use it at night, only after getting out of the shower.
People strongly want to do what feels right, even when what feels right is actively harmful.
