7. Usage Areas and Techniques
The ergonomic design of the massager allows for effective application to various areas:
- Jaw Area: Gently place the contoured part of the massager along your jawline, near the temporomandibular joint. Move it slowly in small circles or hold it stationary for a few seconds.
- Neck: Apply the massager to the upper part of your neck, especially where tension often accumulates.
- Temples/Head: For headache or migraine relief, gently apply to the temples or other areas of the head experiencing tension.
- Gua Sha / Lymphatic Drainage: Use the smooth surface of the device to gently glide across your face and neck in upward and outward motions to promote circulation and reduce puffiness.
Recommended usage time is 10-15 minutes per session, up to 2-3 times per day, or as advised by a healthcare professional.
