A gua sha stone  is a traditional Chinese skincare tool, typically made from jade, rose quartz, or other smooth stones. It's used for a facial massage technique known as gua sha, which involves gently scraping the stone across the skin in upward strokes. This helps to improve blood circulation, reduce puffiness, promote lymphatic drainage, and enhance the overall appearance of the skin.

How to use it
1. Apply a facial oil or serum to create a smooth glide (tallow balm works too)
2. Hold the gua sha stone at a slight angle.
3. Use gentle, upward strokes along the jawline, cheeks, forehead, and neck.
4. Repeat each stroke 3-5 times, working in small sections of the face.

It’s recommended to start with light pressure, gradually increasing as you get familiar with the technique.
