A dermatologist notes that antiperspirant can be more effective when applied before bed, a viewpoint echoed by reports in the Daily Mail. The product is positioned as a cosmetic option that not only reduces sweat but also masks odor through pleasant fragrances. Most antiperspirants contain active aluminum compounds such as aluminum chlorohydrate or aluminum-zirconium tetrachlorohydrex, which work to block sweat ducts and minimize moisture on the skin.
The professional observation highlights a common habit: many people apply antiperspirant in the morning before leaving the house. Yet this routine may not yield the best results. The dermatologist explains that the ingredients in these products are absorbed more effectively at night when the body’s temperature naturally drops, aligning with the body’s sleep preparation processes and increased melatonin production. Melatonin, in turn, has systemic effects that include lower blood pressure, a slower heart rate, and reduced sweating.
Further insights clarify the biological basis for the chosen timing. The skin houses two main types of sweat glands: eccrine and apocrine. Eccrine glands are dispersed across the body and primarily produce clear sweat that helps regulate temperature. Apocrine glands concentrate in areas like the underarms and scalp where hair follicles are present. By applying antiperspirant at night, the active ingredients have a better chance to reach and block the ducts associated with apocrine glands, thereby reducing both sweat production and the characteristic odor linked to these glands.
In related health guidance, another professional noted situations where regular brushing of teeth might not be necessary in certain contexts, underscoring the idea that routine personal care practices should be aligned with current guidance and individual circumstances. The overarching message emphasizes informed decision-making about daily hygiene routines, supported by dermatological and dental perspectives.
