What colour should gua sha marks be?

Light pink is the target — it means you scraped to the right depth and it fades within a few hours to a day. Red patches lasting one to three days are common. Patchy purple means you pressed rather than scraped and can last over a week. Dark spreading purple means too much pressure.

Are gua sha marks toxins leaving the body?

No. Gua sha marks are small capillaries breaking under the skin from mechanical pressure. They are not a measure of toxins or of whether the practice is working, and darker marks do not mean a more effective session — they mean too much pressure.

How long does gua sha bruising last?

Traditional sources give three to seven days for marks to clear naturally. Light pink resolves within hours to a day, red patches in one to three days, and patchy purple can take a week or more. Avoid scrubbing, hot flushing or picking at the skin, as all three slow recovery.

How often is it safe to do gua sha?

One area every three to six days, waiting until any marks have fully faded before repeating it. A few minutes per session, most people pairing it with an evening routine. Weekly per area is sufficient; daily practice is not better and is a common cause of the darker marks and skin irritation people report.

What should you not gua sha?

Do not scrape during pregnancy, menstruation, or if you have a bleeding condition, take blood thinners, or have broken or inflamed skin. Avoid the chest, abdomen, front of the throat and bony prominences. Not after a heavy meal, when very thirsty, or after alcohol. These are traditional contraindications rather than optional preferences.

Gua Sha Bruising: What Each Colour Means, and When to Stop

Free page, and it stays free. Knowing when to stop is the safety half of gua sha, and nobody should have to pay for it. The 21-day ritual is built around the other half — knowing which area to work on a given night, and pairing it with the soak or the pressure point that goes with it.

This is the page most gua sha guides leave out. Everyone tells you what to do. Almost nobody tells you what the marks mean — and that is the part you actually need, because it is how you know whether to do it again next week or stop for a month.

One thing first: gua sha marks are not toxins leaving your body. They are small capillaries breaking under the skin. That is not dangerous in the way the internet sometimes implies, and it is also not a measure of whether the practice is working. Dark marks do not mean you are cleansing anything — they mean you pressed too hard.

What the colours mean

What you see	What it means	How long it lasts
Light pink	You stopped at the right depth. This is the target — the skin is warm and mildly flushed.	A few hours to a day
Red patches	A little firm, and normal. Common on the first try, especially on the back or upper shoulders.	1–3 days
Patchy purple / mauve	You pressed rather than scraped. The dots sit under the skin instead of fading with the flush. Still common and usually not a problem on the body.	Up to a week or more
Dark purple, spreading	Too much. You probably went over the same spot repeatedly, or held the board too perpendicular.	1–2 weeks
Swelling, blistering, weeping skin	Stop now, and do not repeat this area without a clinician's advice. Blistering skin is not a normal result.	See a clinician

Marking takes three to seven days to clear on its own. Don't scrub it, don't hot-flush it, don't pick at it — all three make the recovery slower.

Three signs you have gone too far — stop the area

Stop if

It stings, and keeps stinging after you lift off

Pain that lingers past the scraping is a pressure signal, not a "working hard" signal. Traditional guidance is that gua sha should never be painful.

Lower the angle and lighten, or stop for the day.
Never scrape over a bruise you already have — you will make it worse.

Stop if

The skin feels hot, swollen or tight hours later

This is the after-effect that people push through and then blame on "detox". It is a friction reaction, and it means less pressure and more oil next time.

Cool compress, not ice directly on the skin.
Leave the oil on rather than washing it off.

Stop if

You see pinpoint dots that appear hours later and don't fade

That pattern — delayed, dot-like marks — usually means thin-walled capillaries. It is not dangerous, but it is a signal that this area is not for you at that pressure.

Switch to a lighter tool or skip the area entirely.
Never on the face — see face scraping, where the threshold is much stricter.

Never scrape these

Traditional contraindications — not optional preferences

Pregnancy: abdomen and lower back are absolutely off limits; face and neck are also traditionally avoided.
Menstruation: traditionally avoided, including on the face.
Bleeding conditions such as haemophilia, low platelets or leukaemia, and anyone on blood thinners.
Broken skin, ulcers, infection, eczema, a rash, or any lump of unknown cause in the area.
The chest, the abdomen, the front of the throat, and bony prominences.
Recent injury or surgery in the area.
Severe heart, liver or kidney disease, and anyone severely run down.
Straight after a heavy meal, when very thirsty, or after alcohol.

What to do afterwards

The standard set of aftercare

Leave the scraping oil on and let it absorb. Wiping it off defeats the point of oiling.
Drink warm water — 200–300ml is the figure traditional sources give.
Keep warm and out of the wind. The pores are open; cold air is what traditional guidance warns about.
No cold shower, ideally not for several hours — and no swimming or sauna on the day.
Go gently for the rest of the day. No intense exercise, no alcohol.

How often is safe?

The figure traditional sources agree on is one area every three to six days, and to wait until any marks have fully faded before going back to it. A few minutes, most people pairing it with an evening or bedtime routine. Weekly per area is enough; daily is not better and is the main thing that causes the problems above.

The short version: light pink is right. Purple is too much. Dark purple, swelling or blisters mean stop. And if any of the contraindications above apply to you, don't do it at all — they are traditional rules, not suggestions.
