On July 16 (local time), Wirecutter, a product review publication operated by the New York Times, cited several dermatologists to explain which body areas are appropriate for deodorant application and which areas should be avoided. Deodorant is a cosmetic product that suppresses sweating and prevents odor. Sweat itself is more than 90% water and is odorless, but when skin bacteria break down the organic compounds in sweat, fatty acids are produced, which can result in body odor. Deodorant products typically contain antiperspirant agents and antibacterial ingredients; the antiperspirant agents block sweat glands to reduce perspiration, while the antibacterial ingredients remove skin bacteria and prevent the interaction between sweat and bacteria that generates odor.

Experts recommend that deodorants or antiperspirants should primarily be used only on areas such as the underarms and feet. For those who sweat excessively on their feet, applying deodorant can help prevent blisters and reduce the odor that comes from feet. Dermatologist Aneta Reszko noted, "The skin on the soles is relatively thick, so there are rarely issues when using underarm deodorants or antiperspirants on feet," adding, "For people who sweat a lot on their feet, this can significantly reduce discomfort in daily life." However, she advised that deodorant should not be used on areas with open wounds or injuries.

The experts also stated that there is no need to use deodorant on the chest, back, arms, or legs, and specifically advised against using it on the groin area. The skin in the groin is extremely thin and sensitive, making it easily irritated by fragrances, antibacterial agents, or aluminum compounds. Dermatologist Adrian Chen explained, "Especially when using antiperspirants on the groin, the sweat glands can become blocked, which increases the likelihood of developing painful dermatitis." He further warned that although there are now products labeled "for sensitive areas," many of these also contain fragrances and should be used with caution. If it is absolutely necessary, one should consult a specialist first.

For the torso and limbs, it is more effective to wear clothing with moisture-wicking and quick-drying properties rather than applying deodorant. Wirecutter emphasized, "There is no need to be swayed by marketing that claims you need to use deodorant all over your body."

Deodorant should be applied to completely dry skin after showering. Additionally, for best results, it is most effective to apply deodorant before bedtime.
