Herbal face masks and washes
中药面膜
What it is
In Chinese medicine, a herbal face mask is a preparation of ground herbs, decoctions or pastes applied to the face for a short time, chosen for the pattern being treated and used as a local support to internal treatment rather than as a substitute for it. The tradition calls this group of preparations 面药, facial medicines.
Three forms are used. A mask is a paste left on for ten to fifteen minutes. A wash is a decoction used to rinse the face and then rinsed off. A compress is a cloth soaked in a decoction and laid on for a few minutes. They differ in how long the herb is in contact with the skin, and that changes how much it can irritate.
The classical record is a formulary tradition: the Tang facial-medicine chapter of the 千金要方 alone lists dozens of preparations. This page does not reproduce them as recipes. It describes the practice as it is used now, with the safety that applying herbs to the face requires.
How TCM explains it
Local application is understood to work where it is applied. A herb chosen for Damp-Heat is used on oily, congested skin; a herb chosen to move Blood is used on dusky, fixed discolouration; a cooling herb is used where the face flushes. The reasoning is the same as for an internal formula, applied to the surface.
That does not make the mask a treatment. The tradition treats facial preparations as support: something used alongside the internal formula, or between courses of treatment, to help the surface while the pattern is addressed. A mask cannot change a pattern on its own, and no page in this section presents one as a substitute for treating a condition.
The other half of the reasoning is about what not to use. A mask chosen for the wrong pattern can make the skin worse, which is why the table below pairs each skin picture with the herbs traditionally used for it, and why the safety section comes before the method.
Which skin pictures it is used for
| What you see | TCM pattern | What is traditionally used |
|---|---|---|
| Oily, congested skin with blackheads and no active inflammation | Damp-Heat | A cooling, drying wash or thin mask: Ku Shen, Huang Bo, Yi Yi Ren |
| Dull complexion with fixed, dusky discolouration | Blood Stagnation | A mask with Bai Zhi and Dong Gua Zi, used at night and washed off |
| Flushing and heat in the face without active inflammation | Wind-Heat | A cool compress of Ju Hua or Sang Ye, left on for minutes only |
| Dry, rough skin needing softening, as in Skin dryness | Blood Deficiency | A thin, moistening mask with Gan Cao or Bai Zhu, rinsed before it dries |
| Active acne, a rosacea flare, eczema or broken skin | Not suitable | No mask, wash or compress until the skin has settled |
Before you start: who should not do this
Before you start: who should not do this
Anything applied to the face can react, and herbs are not automatically gentle. Read this before the method.
Patch test every preparation first. Apply a small amount to the inner forearm, leave it for 24 hours, and check for redness, itching or swelling. A herb that has never been used on your skin gets its own test.
Do not apply a mask, wash or compress if you have:
- broken, cut, sunburnt or peeling skin, or an active cold sore;
- active acne lesions, or a rosacea flare;
- an eczema or dermatitis flare, or any weeping skin;
- had a chemical peel, laser treatment, microneedling or a facial procedure in the past two weeks;
- a known allergy to any ingredient, including honey, dairy, nuts or the herb itself;
- a skin infection or a feverish illness.
Keep the preparation simple. One or two herbs at a time is enough. Do not add essential oils, lemon juice, vinegar or alcohol to a mask: all of them irritate skin, and the essential oils are far more concentrated than the herb they come from.
Never leave a mask on until it dries and cracks. That pulls moisture out of the skin, and the traditional preparations are meant to be rinsed while still moist.
Pregnancy. Most herbs used topically in these preparations are not the ones flagged as unsafe in pregnancy, but a patch test and a word with a practitioner are sensible. Avoid the herbs that are flagged on their own pages.
Stop at once and see a doctor if you get spreading redness, swelling, blistering, hives, pain, or a reaction that does not settle after washing the preparation off.
How it is done
Ten to fifteen minutes, once or twice a week, with a patch test done beforehand. The method is the same whether the herb is a powder, a decoction or a paste.
- Patch test. On the inner forearm, 24 hours ahead, with the exact preparation you intend to use.
- Cleanse. Wash the face with lukewarm water and pat dry. Do not scrub or exfoliate first.
- Make the preparation. For a powder, mix a teaspoon with just enough water, honey or plain yoghurt to make a soft paste that holds together. For a decoction, simmer the herb in water for 15 minutes, strain, and cool to lukewarm.
- Apply thinly. Spread a thin, even layer, avoiding the eyes, the eyelids and the lips. Leave the skin around the eye clear.
- Leave it on for ten to fifteen minutes. Set a timer. The preparation should stay moist; if it starts to dry and crack, rinse it off early.
- Rinse with lukewarm water. Use your hands or a soft cloth, and do not rub. Cool water is fine; hot water is not.
- Moisturise immediately with a product the skin already tolerates.
- Clean up. Throw the preparation away, wash the bowl and the cloth, and wash your hands.
Afterwards. Once or twice a week is the usual routine. The skin may be slightly pink for a few minutes. It should not sting, itch or feel tight. If it does, the preparation was too strong for the skin or stayed on too long, and it should not be repeated.
The herbs used
The herbs below are the ones with a documented traditional use on the face and an existing page in this compendium. Each is used as a single-herb preparation first, so that a reaction can be traced to one ingredient.
For oily, congested skin. Ku Shen (苦参, sophora root) and Huang Bo (黄柏, phellodendron bark) are the cooling, drying pair, used as a wash. Yi Yi Ren (薏苡仁, coix seed) is the gentler option, ground into a thin paste.
For dull, dusky skin. Bai Zhi (白芷, Dahurian angelica root) has a long record as a facial powder. It makes skin react to sunlight, so it is used at night and the face is kept out of the sun afterwards. Dong Gua Zi (冬瓜子, winter melon seed) was traditionally ground into face pastes; its own page covers the historical detail.
For dry, rough skin. Gan Cao (甘草, licorice root) is used as a cooled decoction, and Bai Zhu (白术, atractylodes rhizome) as a thin powder mask. Fu Ling (茯苓, poria) is the mildest of the group and is used where the skin is puffy as well as dull.
For flushing and heat. Ju Hua (菊花, chrysanthemum flower) and Sang Ye (桑叶, mulberry leaf) are used as cool compresses rather than masks.
Four further herbs are traditional in these preparations but do not yet have pages here: Bai Ji, Zhen Zhu (pearl), Bai Jiang Can and Bai Fu Zi. They are listed in this section's missing pages and are not described on this page until their own safety sections exist. Bai Fu Zi in particular is a toxic raw herb and should not be used at home.
What the evidence says
At least one verified human study for the condition on this page, with limited or low-quality evidence. Editorial policy
Limited studies. These are the human studies we found on PubMed (searched October 2026).
The trials tested Chinese herbal masks for acne. No trial has tested them for brightness, glow or ageing. That sentence defines what the badge covers: it applies to a herbal mask used on acne, and it does not extend to the traditional cosmetic uses described elsewhere on this page.
The trial enrolled 233 people with acne vulgaris of grade I to III and randomised them to a Chinese medical facial mask applied twice a week (113 people) or to 5% benzoyl peroxide gel (120 people) for four weeks. The total effective rate was 70.8% in the mask group and 55.8% in the control group, and adverse reactions were reported in 1.8% and 2.5% respectively. Two limits matter. It is a single Chinese-language trial, and its intervention is described as "comprehensive therapy", so what was actually applied is not clear from the abstract. The population is acne, which has its own page in this compendium. Zhongguo Zhong Xi Yi Jie He Za Zhi, 2012, PMID 22679722.
A second, much older report described 32 cases treated with blood-letting, cupping and a Chinese drug facemask together. It is an uncontrolled case series with three interventions at once, and it cannot support a claim for the mask.
The laboratory literature is a separate matter and is not used here to support any effect on people. A review of pearl powder covers its materials and biomedical applications, and includes beauty use in its scope. A review of Tremella fuciformis states that most studies are in vitro and animal and calls for clinical research. A laboratory study reported antioxidant activity in mung bean sprout extract and its safety for cosmetic use. None of these is evidence that a mask applied to the face does anything for a person.
Where the badge stands. Limited studies, on the strength of that one randomised trial in acne. Everything else on this page is traditional use: choosing the preparation by pattern, the forms of mask, wash and compress, and the traditional aims of softening a dry surface and moving a congested one. None of that has been tested, and the badge does not cover it.
Common mistakes
- Skipping the patch test. It is the single most useful step on this page, and it takes a day.
- Mixing several herbs at once. If a preparation reacts, you cannot tell which ingredient did it.
- Adding essential oils, lemon juice, vinegar or alcohol. All of them irritate skin, and none of them is needed.
- Letting the mask dry and crack. Rinse while it is still moist.
- Leaving it on for an hour "to work". Ten to fifteen minutes is the routine; longer contact irritates rather than helps.
- Using it during a flare. Active acne, rosacea and eczema are reasons to stop, not to try harder.
- Scrubbing it off. Rinse with lukewarm water and your hands.
- Applying over the eyelids or the lips. Both are left clear.
- Treating a mask as a substitute for treatment. It is a support, and the condition pages are where treatment is described.
Common questions
Are herbal face masks safe?
Most are low risk when the patch test is done and the exclusions are respected, and none is risk-free. Herbs can cause contact reactions, and the ones used for cooling or drying can irritate if left on too long. The patch test and the stop rules on this page are what make the practice reasonably safe.
How often should I use a herbal mask?
Once or twice a week, for ten to fifteen minutes, and not during a flare. More often does not help and increases the chance of irritation.
Can a herbal mask clear acne?
The tradition uses cooling, drying preparations on oily, congested skin, and one small trial in acne exists. That is not enough to call a mask a treatment for acne, and acne has its own page in this compendium.
What can I mix the powder with?
Water, honey or plain yoghurt. Do not add essential oils, lemon juice, vinegar or alcohol. If you are allergic to dairy or nuts, use water.
Can I make a mask from a herb in my kitchen?
Only from a herb that has a page here with a safety section, and only after a patch test. Several traditional herbs are toxic or cause photosensitivity, and Bai Fu Zi in particular should not be used at home.
Should I use a mask if my skin is sensitive?
Patch test first, choose the mildest herb, keep the contact time short, and stop at the first sign of stinging. The sensitive skin page sets out the wider approach.
