Apply Driclor to dry armpits, hands or feet before going to bed at night. Let the Driclor dry naturally. Wash it off in the morning and don't reapply it during the day. You can use your normal deodorant or perfume in the day if you want to, but don't use other antiperspirants as well.
To begin with you should apply Driclor every night until your sweating is controlled in the day. You can then reduce how often you apply it - you may need to only apply it twice a week or less to keep your sweating under control. Bear in mind that if your skin is getting irritated you are probably using the product too often.
Precautions for use: After shaving or waxing, don't apply the product within 48 hours.
