The common mistake everyone makes that renders deodorant ineffective

If you want your deodorant to be truly effective, doctors advise applying it at this specific time.

The fragrance, packaging, and ingredients (free from parabens, perfumes, aluminium salts, etc.) are not the only things to consider before buying and using your deodorant. Several dermatologists and doctors highlight the importance of another factor to make your care routine fully effective. They explain that a large number of users are not using their deodorant correctly. "This advice may sound strange, but it helps to optimise the effects of deodorant," says Carla Valette, a medical intern at CHU de Toulouse. "In fact, you should apply deodorant in the evening, before going to bed, not in the morning."

When Night Falls

Known for her TikTok videos and her educational content online, she supports her statement by pointing out that at night, the sweat glands responsible for perspiration are less active than during the day, as reported by Linternaute. By applying your care product to clean underarms, ideally after showering, you enhance its effects. The deodorant is absorbed more deeply and, as a result, is more effective. “If you applied it in the evening, don’t reapply during the day so as not to overload your underarms,” adds Carla Valette.

Or before daytime

On the other hand, if you're more active at night and daytime serves as your rest period, experts recommend applying your deodorant in the morning. The most important thing is to use the product before the time when you are least active, as highlighted by a study published in the Journal of the American Academy of Dermatology.

This will help you better understand why many deodorant brands claim "effective for 24h". In fact, the products are absorbed at night over approximately 10 hours, and are activated during the following 12-14 hours.
