The best time to apply deodorant for all-day protection: Know expert tips

Experts suggest that applying antiperspirant at night, before bed, maximizes its effectiveness.

Morning application can be a useful top-up, but the primary application should be at night for optimal dryness, reduced irritation, and better skin health.
