Gua sha facial benefits: what the research shows

The difference is pressure, and it changes what the treatment can do. Body gua sha on the back, neck or shoulders aims to raise sha on purpose. Facial gua sha uses what Cleveland Clinic calls very light pressure, because the structure of the face is thinner than the rest of the body, and it aims for a brief flush and less puffiness rather than marks.

The material matters less than the marketing suggests. Jade and rose quartz tools are the familiar ones, but the licensed acupuncturist Cleveland Clinic quotes says a small wooden spoon works just as well. What counts is a smooth, unchipped edge and a shape that sits flat against the cheek and jaw.

The gua sha facial benefits with any data behind them are a short rise in skin blood flow (so far measured only after body gua sha), a possible drop in puffiness and, in one small trial, a slight change in facial contour. No controlled study we found shows that gua sha erases wrinkles, permanently tightens sagging skin or "detoxes" the face. Three studies carry most of the weight, and only the third looked at faces.

Researchers at University Hospital Essen in Germany used laser Doppler imaging on 11 healthy volunteers after a single gua sha session on the back. Blood flow in the treated skin rose about fourfold for the first 7.5 minutes and stayed significantly raised for the full 25 minutes they measured. Every volunteer also reported less muscle pain straight away, and there were no adverse reactions (Nielsen et al., Explore, 2007). This was firm body gua sha that raised sha, so a light facial stroke should be expected to do less.

Several of the same researchers, at Kliniken Essen-Mitte, randomized 48 people with chronic neck pain to one gua sha treatment or a heat pad. A week later, pain on a 100 mm scale had improved by about 30 mm more in the gua sha group, close to a third of the scale, with gains in pain on movement and in neck disability scores as well (Braun et al., Pain Medicine, 2011). Patients knew which treatment they had, follow-up ended at 7 days, and the authors wrote that the value of gua sha in long-term care "remains to be clarified."

A 2025 randomized trial from Yonsei University in South Korea tested facial gua sha directly. Thirty-four women aged 20 to 50 did 10 minutes of self-massage five days a week for 8 weeks, half with a gua sha tool and half with a facial roller. Measured distances across the lower face and jawline shrank by 2.23 to 2.40 mm in the gua sha group, and its muscle stiffness readings dropped (Ahn et al., Journal of Cosmetic Dermatology, 2025). A change of about 2 mm is small, and it was measured with instruments rather than judged by eye.

It may, for a short time. Cleveland Clinic explains that the gentle downward motion of gua sha may help get lymphatic fluid moving, which may lessen facial puffiness, and it adds that there is not enough high-quality research to declare the benefits definitively. None of the three studies above measured puffiness at all.

If puffiness is your reason for trying it, the direction of the strokes matters more than the stone. Lymph from the face drains toward the small nodes in front of the ears and under the jaw, then down the sides of the neck, which is why most routines finish with a few light strokes down the neck. Some people keep the stone in the fridge, because cold narrows surface blood vessels for a few minutes; none of the studies above tested that habit. Expect any change to be temporary.

Neither has been shown to be better overall; in the one head-to-head trial they did different things. Both groups in the 2025 study changed facial contour, and the roller group slightly more, by 2.75 to 3.26 mm. The gua sha group showed lower muscle stiffness, while the roller group gained skin elasticity of about 8%, and the authors concluded that gua sha works mainly on muscle and the roller mainly on skin.

In practice the choice comes down to comfort. A roller covers broad areas quickly, and a flat gua sha tool gives more control along the jaw and under the cheekbone, where most facial routines spend their time.

Facial gua sha has very little research of its own, and the 2025 trial shows why that matters. It had no untreated group, so part of the change could come from 8 weeks of attention and any kind of facial massage. The tool was a stainless steel and plastic device rather than jade. The volunteers were healthy women aged 20 to 50 doing their own massage, and nobody was measured after the 8 weeks ended, so it is unknown whether the change lasts once you stop. People with eczema, severe acne or rosacea were excluded, so the results say nothing about sensitive skin.

No trial has compared jade with other stones, tracked wrinkles over months, or confirmed the lymphatic drainage claims. The 2023 dermatology letter mentioned earlier reviewed popular consumer articles on gua sha, jade rollers and facial massage. They promised fewer wrinkles, less puffiness, better lymphatic flow and even migraine relief with very little research behind them, and only 30% mentioned the risks reported in medical journals: contact dermatitis, minor burns and infection.

In a spa facial, gua sha also arrives with cleansing, steam, serum and a mask, so any glow afterwards has several possible causes. A fair expectation is a relaxing treatment that may leave your skin looking fresher for a while.

Skip it, or ask your doctor first, if any of the points below apply. Gua sha presses on skin and the small blood vessels under it, and each caution follows from that.

The Jade Gua Sha Facial at O2 Head & Beauty Spa runs 75 minutes and costs $196 at the regular rate or $98 at the member rate; ask the front desk how membership works. The booking page describes it as a facial "featuring jade gua sha and facial sculpting techniques to improve circulation, lift facial contours, and restore a healthy glow." The circulation claim has short-term support from body gua sha on the back, and the contour claim rests on one small trial.

It is the only facial on the facial menu that lists gua sha. The 60 minute Customized Facial has the same base without it, and the 90 minute Luxury Facial adds an aqua peel, LED light therapy and a scalp, neck and shoulder massage instead. When you book, mention anything from the skip list above, such as rosacea, a breakout, blood thinners or a recent injectable, so the person doing your facial knows before the gua sha step begins. The menu lists these steps for the gua sha facial:

Use light pressure, plenty of slip and one-way strokes from the center of the face outward. The steps below follow Cleveland Clinic's advice and the routine from the 2025 trial, which used 10 minutes a session.

Before the first stroke, run a fingertip along the tool's edge. A chip or crack can scratch the skin, so retire a damaged tool. Patch-test any new oil on your jaw a day ahead if your skin reacts easily, since contact dermatitis is one of the reported risks.
