According to Healthlinegua sha is typically performed on the back, buttocks, arms, and legs, and more delicately on the face and neck. Practitioners use oil or serum to help the tool glide smoothly across the skin.
This technique is believed to clear stagnant energy, or chi, which is thought to contribute to inflammation in the body. By scraping the skin in specific patterns, gua sha is said to enhance blood flow and alleviate pain.
A study from 2007 found that gua sha could boost circulation in micro-vessels for up to 25 minutes post-treatment. Participants also experienced immediate relief from muscle pain, with benefits persisting to follow-up visits.
Medical News Today notes that applying pressure to specific points on the face and neck during gua sha can help reduce puffiness by promoting lymphatic drainage and muscle relaxation.
A 2022 article in the Journal of Cosmetic Dermatology suggests that short-term use of gua sha can diminish puffiness through enhanced lymphatic drainage. Regular sessions may also improve vascular dilation responses.

While gua sha is generally safe, there are a few potential side effects to be aware of:
Bruising
The technique can cause small capillaries near the skin’s surface to burst, leading to distinctive red or purple bruises known as sha. These bruises, typically tender and healing within a week, can be managed with over-the-counter pain relievers like ibuprofen. Gentle heat may also help reduce inflammation and discomfort.
Skin damage
There’s a slight risk that gua sha can break the skin during treatment, increasing infection risks. Practitioners must sterilize their tools thoroughly between sessions to prevent this.
Bacterial infection
Although rare, bacterial skin infections can occur, especially if the skin is torn or bleeds. Always ensure that gua sha tools are cleaned properly between uses, or choose a provider who upholds stringent hygiene practices.
Additionally, gua sha should not be used on open wounds or irritated skin. Individuals using blood thinners or with clotting disorders should consult with healthcare professionals before beginning gua sha treatments.
