How long should you wait before doing gua sha again?

Generally, it is recommended to wait 3–7 days between gua sha sessions. This interval is ideal for routine health maintenance, though adjustments should be made based on individual physical conditions. Detailed explanations are as follows:

Gua sha may leave marks of varying intensity on the skin, reflecting the adjustment of subcutaneous qi and blood circulation. These marks require time to fade. For healthy individuals using gua sha for regular wellness, a 3–7 day interval allows sufficient recovery of the skin and underlying tissues, preventing discomfort caused by excessive or frequent stimulation.

If experiencing mild symptoms such as a slight cold or localized soreness, and if the marks from the first session are faint, another session may be performed after 3 days depending on recovery. However, if the marks are deep, the skin shows slight redness or swelling, or the individual has a relatively weak constitution, the interval should be extended to 5–7 days to avoid aggravating skin damage or depleting qi and blood.

After gua sha, it's important to stay warm and avoid exposure to cold. Bathing is not recommended within 24 hours. Regular gua sha should follow the principle of gradual progression, with intervals adjusted according to personal response, in order to maximize its regulatory benefits and support overall well-being.
