Gua sha
Gua sha is a traditional Chinese medicine technique in which the lubricated skin is repeatedly stroked with the smooth edge of a tool to raise circulation and release stagnation. On the body it produces a temporary reddish marking known as “sha”; the gentler facial form, popular in skincare, does not. Both work on the same principle of moving qi and Blood to relieve tension and support the body's natural functions.

1. What is gua sha?
Gua sha (pronounced “gwah-shah”) is a manual technique within traditional Chinese medicine (TCM). The name means “to scrape” (gua) “sand” (sha) — sha referring to the small reddish spots that appear on the skin when the technique is applied with therapeutic pressure. It is closely related to cupping therapy: both aim to draw stagnation to the surface and restore the free flow of qi and Blood.
Traditionally a smooth-edged tool — a ceramic soup spoon, a coin, or a shaped piece of jade, horn or stone — is stroked firmly across lubricated skin. In recent years the gentler facial gua sha has become popular worldwide as a skincare practice, using a flat jade or rose-quartz tool with light pressure and no marking.
2. History of gua sha
Gua sha is an old folk and clinical practice found across China and much of East and Southeast Asia, where related versions are known by other names — cao gio (“catch the wind”) in Vietnam, for example. For centuries it was a household remedy applied at the first sign of a cold, fever or heatstroke, often using whatever smooth-edged object was to hand: a coin, a spoon or a worn jade ornament.
Alongside this domestic tradition, gua sha has long been part of formal TCM practice, recorded in classical medical texts and still taught as a treatment technique today. The facial form now widely seen in modern skincare is a recent and much gentler offshoot of this older, firmer therapeutic practice — the two share a name and a tool shape but little else.
3. The technique
For therapeutic body gua sha, the practitioner applies oil or balm to the area — commonly the back, neck, shoulders or limbs — and strokes the skin with the rounded edge of the tool in short, brisk, repeated movements in one direction. The pressure is firm enough to raise the characteristic sha — small red or purplish petechiae that indicate where stagnation has been released. The sha is not a bruise and is not painful; it typically fades within two to five days.
Facial gua sha is entirely different in intensity: a flat tool is glided gently along the contours of the face and neck with light pressure, producing no marks and aiming to relax facial muscles, support lymphatic drainage and give a temporary depuffed, refreshed appearance.
4. Gua sha tools
Traditionally gua sha needs nothing more than a smooth, rounded edge. Classic tools include the Chinese ceramic soup spoon, a coin with smoothly milled edges, and purpose-shaped pieces of water-buffalo horn, jade or bian stone. Modern therapeutic tools are usually made of stainless steel, jade or stone, contoured with one or more edges to fit different parts of the body.
Facial gua sha tools are different in shape — flat, often heart-shaped or comma-shaped pieces of jade or rose quartz designed to glide over the contours of the face. Whatever the tool, the essentials are the same: a smooth edge, a clean surface, and enough lubricant on the skin so that the tool slides rather than drags.
5. How gua sha works
In TCM terms, gua sha moves stagnant qi and Blood, releases the Exterior, clears Heat and disperses Wind, Cold and Damp — which is why it has traditionally been used at the first sign of a cold or fever as well as for musculoskeletal tension.
From a modern perspective, the stroking action produces a sharp, controlled increase in microcirculation in the treated tissue. Research has measured a several-fold rise in local blood flow after gua sha, along with reductions in markers of inflammation and the release of a protective enzyme, heme-oxygenase-1. This improved circulation, together with stimulation of sensory nerves and release of muscle and fascial tension, is thought to underlie its pain-relieving and decongesting effects.
6. Body gua sha vs facial gua sha
It is worth being clear that these are two quite different practices that share a name and a tool shape:
- Therapeutic body gua sha — firm pressure, raises sha, used clinically for pain, tension and the early stages of a cold. Applied by a TCM practitioner.
- Facial gua sha — light pressure, no marking, a self-care and skincare practice for relaxing facial tension and reducing puffiness. Widely done at home.
The dramatic “before and after” images associated with gua sha online almost always show the body form; facial gua sha is far gentler.
7. What gua sha is used for
Body gua sha is used most often for neck, shoulder and back tension and pain, for muscle stiffness, and traditionally to shorten the early stage of a cold or to relieve a stiff, achy “coming-down-with-something” feeling. It has also been studied for perimenopausal symptoms and chronic neck pain, with encouraging results.
Facial gua sha is used cosmetically for facial tension, jaw tightness and a temporarily puffy or tired-looking complexion. It is best understood as a relaxing self-care ritual that gives a short-lived freshening effect — not a substitute for medical or dermatological treatment.
8. Safety and what to expect
Gua sha is generally very safe when done correctly. The sha marks on the body look more dramatic than they feel — they are not bruises and fade within a few days. Gua sha should be avoided over broken or inflamed skin, recent injuries, moles or skin lesions, and in people who bruise very easily or take blood-thinning medication. It is not done over the abdomen or lower back in pregnancy. Facial gua sha should be gentle, and should always use a clean tool and adequate slip from a facial oil to avoid dragging the skin.
9. Commonly asked questions
Do you offer gua sha at your clinic?
No. Gua sha is not a therapy offered at this clinic — this page is for information only. Dr (TCM) Attilio D'Alberto practises acupuncture, Chinese herbal medicine, moxibustion and cupping therapy. The closely related cupping therapy is available.
Is gua sha the same as cupping?
They are related but different. Cupping uses suction from cups to lift the tissue; gua sha uses stroking pressure from a tool's edge. Both aim to release stagnation and improve circulation, and both can leave temporary marks on the body.
Are the red marks from gua sha harmful?
No. The reddish sha raised by body gua sha is not a bruise and is not harmful; it reflects increased microcirculation in the area. Facial gua sha, done with light pressure, does not produce marks at all.
How long do gua sha marks last?
The sha raised by body gua sha usually fades within two to five days, a little like the marks left by cupping. The exact time varies from person to person. Facial gua sha, done with light pressure, leaves no marks.
Can I do gua sha at home?
Light facial gua sha is commonly done at home as a self-care practice, and is reasonably safe provided the tool is kept clean, the skin is well lubricated with a facial oil and the pressure is gentle. Therapeutic body gua sha — the firm form that raises sha — is best left to a trained practitioner, who can judge the right areas, the right pressure and when it is not appropriate.
How often can gua sha be done?
Body gua sha is usually not repeated on the same area until the previous sha has fully faded — generally several days to a week. Gentle facial gua sha can be done much more frequently, even daily, as it does not mark the skin.
