Step 1: Sheath adjustment

1. Before wearing the girdle, make sure it is clean and dry.
2. Place the girdle over your face, making sure that the part that covers the chin is correctly positioned.
3. Use the adjustable straps to adjust the girdle to the size of your head. Make sure it's snug but comfortable.

Step 2: Wearing the sheath

1. Wear the girdle for a maximum of 30 minutes per session, once a day. You can wear the girdle during your daily activities, but not while you sleep.
2. For best results, use the girdle regularly for at least 2 to 6 weeks.
