When it comes to gua sha, it’s important to use the proper technique. Because it can create a rash or bruising, you want to make sure you’re not causing any lasting damage. Trina Jefferson of Kerstin Florian recommends being careful of using anything that sensitizes or thins the skin prior to the treatment, such as specific medications, overexposure to the sun, or glycolic acid peels. It’s also especially important to use the proper pressure, depending on what area you’re targeting.
According to Ada Ooi of 011 Skincare London, there are many schools of thought in regard to gua sha. Some prefer a light touch, and others believe the more pressure the better. As a result, redness and bruising can occur even with the proper technique. For that reason alone, educating your clients on the treatment is essential.
“I teach my patients how to properly perform gua sha at home,” says Elizabeth Trattner, A.P. “Unfortunately, there are many bloggers and influencers who are literally using gua sha tools like windshield wipers on their faces, or many women I meet who are doing it way too hard and not supporting their skin.”
While it is generally safe and beneficial for most people, Ooi does not recommend it for clients who are in their first trimester of pregnancy, on blood-thinning medication, bleed easily, have skin or vein issues, or recently had Botox, fillers, or cosmetic surgery.
