1. Apply Nuud to the armpit whenever you wish, before or after showering, morning or evening. 2. How much? Nuud is super concentrated. A pea-sized drop per armpit is sufficient. 3. How often? Initially, you may need to experiment to find the suitable application frequency. Some people apply it once a week, while others apply daily but reduce frequency over time. The average usage is every 3 days. Deodorant and Roll On
