This eye mask and gua sha set utilizes terahertz stone, a material known for its ability to retain and transfer temperature for both cooling and heating therapy. The set includes a contoured eye mask and a gua sha tool, each crafted from authentic terahertz stone. When used cold, the eye mask helps reduce puffiness around the eyes and soothes tired areas. When warmed, it can promote relaxation and ease tension in the eye region. The gua sha tool is designed for facial and body use, supporting lymphatic drainage by gently stimulating circulation along the jawline, cheeks, and neck. This may aid in reducing fluid retention and promoting a more contoured appearance over consistent use. The terahertz stone composition is smooth and non-porous, making it easy to clean and suitable for repeated application. The set is appropriate for individuals seeking non-invasive skincare tools to incorporate into daily routines for facial relaxation and temporary reduction of puffiness. It is compatible with most skin types, including sensitive skin, as it does not rely on active ingredients or chemicals. The dual-temperature functionality allows users to adapt the tools to personal preference or specific needs, such as cooling for morning de-puffing or warming for evening relaxation. The design is compact and portable, facilitating use at home or while traveling. This product is intended as a complementary tool within a broader skincare regimen, not as a standalone treatment for medical conditions. Regular cleaning and proper storage are recommended to maintain the integrity of the terahertz stone.
