Itchy skin from synthetic clothes

You peel off a gym shirt or a pair of leggings, and your skin is red and itchy. The itch may sit where the seams press, or under the waistband. Cotton feels fine, but polyester, nylon or stretch fabric sets you off.

Synthetic fabric traps heat and sweat against your skin. Warm, damp skin gets sore and itchy faster than dry skin. Rubbing from a tight fit adds to it.

Dyes, coatings and stretch fibres can also bother you. Some people react to spandex, or to the finish on wrinkle-free shirts. New clothes may still carry bits left over from the mill, so a first wash is common advice.

When to see someone

See a doctor if the rash blisters, weeps or spreads past the edge of the fabric. Get help right away if your lips or throat swell, or you feel short of breath. Also get checked for itch that wakes you at night, skin that cracks and bleeds, or a patch that does not clear in two weeks.

How to read the grades below

Below is a list of remedies people use for skin trouble linked to plastic fibres. Each one carries a grade for how strong the research behind it is. A high grade means solid proof; a low grade means the proof is thin or mixed.

What would you rather focus on about microplastics?

I want to back up my liver's ordinary clearing work

  1. NAC (N-Acetyl cysteine)

    Centuries of traditional use· Limited human trials so far (Evidence grade D · Traditional use long-standing)Long-standing traditional staple

    Precursor that replenishes glutathione

    Why it may be relevant
    Raises glutathione, which is the pathway the body already uses to handle foreign compounds and the oxidative stress they generate.
    Why try it
    Raises glutathione, which is the pathway the body already uses to handle foreign compounds and the oxidative stress they generate.
    Dose or use
    Follow product labelling; with food if it unsettles your stomach.
    Time to results
    Typically 4-8 weeks of consistent use
    Key study
    Traditionally used to support glutathione and antioxidant defenses; its use specifically for microplastic-related oxidative stress has not been confirmed in controlled clinical trials.
    Caution
    Can cause nausea; not a substitute for reducing intake, which is the only lever that changes the exposure. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  2. LV3 (Taichong)

    Centuries of traditional use· We looked for human evidence and found none worth a grade (Evidence reviewed, no grade justified · Traditional use long-standing)Long-standing traditional staple

    Acupressure point for liver and detox pathways

    Why it may be relevant
    Used in acupressure to support liver qi, which practitioners associate with the body's cleansing work.
    Why try it
    Used in acupressure to support liver qi, which practitioners associate with the body's cleansing work.
    Dose or use
    Firm pressure for one to two minutes per side, daily.
    Time to results
    Typically 2–6 weeks of regular practice
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Offered as a traditional practice with no evidence behind it for this exposure; harmless, and ranked last for that reason. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  3. Milk Thistle (Silybum marianum)

    Centuries of traditional use· Limited human trials so far (Evidence grade D · Traditional use long-standing)Long-standing traditional staple

    Classic liver-support herb

    Why it may be relevant
    Supports the liver doing the ordinary work of processing what reaches it, rather than acting on plastic specifically.
    Why try it
    Supports the liver doing the ordinary work of processing what reaches it, rather than acting on plastic specifically.
    Dose or use
    Follow product labelling; standardised silymarin is what has been studied.
    Time to results
    Typically 4-8 weeks of consistent use
    Key study
    Traditionally used to support liver function; its use specifically for microplastic exposure has not been confirmed in controlled clinical trials.
    Caution
    Can interact with drugs cleared by the liver. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  4. Cruciferous Vegetables (DIM/Sulforaphane)

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade D · No traditional record)

    Activates liver detox and antioxidant enzymes

    Why it may be relevant
    Switches on the phase II enzymes that conjugate and clear foreign compounds - food-first, and useful whether or not plastics are your concern.
    Why try it
    Switches on the phase II enzymes that conjugate and clear foreign compounds - food-first, and useful whether or not plastics are your concern.
    Dose or use
    Food first, most days; supplements at label dose only if you will not eat the vegetables.
    Time to results
    Typically 4–8 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Very large amounts can affect thyroid function where iodine is already low. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

I want to close a nutrient gap that weakens those defences

  1. Selenium Deficiency

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade D · Traditional use recognised)Recognised traditional use

    Cofactor for your antioxidant enzymes

    Why it may be relevant
    Selenium is a cofactor for the antioxidant enzymes doing this work, so a shortfall weakens defences you already have.
    Why try it
    Selenium is a cofactor for the antioxidant enzymes doing this work, so a shortfall weakens defences you already have.
    Dose or use
    Ask your provider to test before supplementing; the safe range is narrow.
    Time to results
    Varies; depends on restoring adequate status
    Key study
    Selenium's role as a cofactor for antioxidant enzymes is established; addressing deficiency specifically for microplastic exposure has not been confirmed in controlled clinical trials.
    Caution
    Selenium is toxic in excess - correct a confirmed shortfall, never top up on a guess. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  2. Vitamin E Deficiency

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade D · Traditional use recognised)Recognised traditional use

    Guards cell membranes from oxidative damage

    Why it may be relevant
    Vitamin E protects cell membranes from oxidative damage, and a genuine gap leaves that protection thin.
    Why try it
    Vitamin E protects cell membranes from oxidative damage, and a genuine gap leaves that protection thin.
    Dose or use
    Food sources first; ask your provider before supplementing.
    Time to results
    Varies; depends on restoring adequate status
    Key study
    Vitamin E's role as a membrane antioxidant is established; addressing deficiency specifically for microplastic exposure has not been confirmed in controlled clinical trials.
    Caution
    High-dose vitamin E supplements interact with anticoagulants. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  3. Vitamin C (Effervescent Powder)

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade D · No traditional record)

    Water-soluble antioxidant and immune support

    Why it may be relevant
    Everyday antioxidant support for the oxidative side of the exposure; food sources count toward the same thing.
    Why try it
    Everyday antioxidant support for the oxidative side of the exposure; food sources count toward the same thing.
    Dose or use
    Follow product labelling.
    Time to results
    Typically 2–6 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    High doses cause diarrhoea and raise urinary oxalate, which matters with a history of kidney stones. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

I want to cut down what I take in every day

  1. Activated Charcoal

    Looked, and found nothing conclusive· We reviewed the research for this use and found nothing that justified a grade (Evidence reviewed, no grade justified · No traditional record)

    Binds unwanted particles in the gut

    Why it may be relevant
    Traditionally taken to trap ingested material in the gut before it is absorbed.
    Why try it
    Traditionally taken to trap ingested material in the gut before it is absorbed.
    Dose or use
    Follow product labelling, never within two hours of medication or supplements.
    Time to results
    Acute effect within hours of use
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Its adsorption works on small molecules, and plastic particles are orders of magnitude larger than that - included because it is widely suggested, graded accordingly. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  2. Chlorella

    Looked, and found nothing conclusive· We reviewed the research for this use and found nothing that justified a grade (Evidence reviewed, no grade justified · No traditional record)

    Traditionally used to bind and clear toxins

    Why it may be relevant
    Taken as a daily gut binder in the hope of carrying particles out in stool.
    Why try it
    Taken as a daily gut binder in the hope of carrying particles out in stool.
    Dose or use
    Follow product labelling, with food.
    Time to results
    Typically 4–8 weeks of consistent use
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    The binding evidence behind chlorella is about heavy metals, not polymers, and it binds nutrients and medicines too. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  3. Probiotics (Lactobacillus plantarum P8)

    Looked, and found nothing conclusive· We reviewed the research for this use and found nothing that justified a grade (Evidence reviewed, no grade justified · No traditional record)

    Supports gut barrier and microbial balance

    Why it may be relevant
    Supports the intestinal barrier that decides how much of what you swallow actually crosses into you.
    Why try it
    Supports the intestinal barrier that decides how much of what you swallow actually crosses into you.
    Dose or use
    Follow product labelling, daily, with or after food.
    Time to results
    Typically 4–8 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Barrier benefits are strain-specific and this strain has not been studied for this exposure. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  4. Water Filtration Systems

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade D · No traditional record)

    Filters plastics from drinking water

    Why it may be relevant
    Drinking water is the single largest everyday source for most people, and filtration is the only step here that reduces intake rather than responding to it.
    Why try it
    Drinking water is the single largest everyday source for most people, and filtration is the only step here that reduces intake rather than responding to it.
    Dose or use
    Choose a filter rated for particulate removal and replace cartridges on schedule.
    Time to results
    Immediate reduction in water-based exposure
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Bottled water is not the safe alternative - it generally tests higher than filtered tap. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

    Works in every cell to recycle antioxidants

    Why it may be relevant
    Recycles glutathione and vitamins C and E, supporting the antioxidant system rather than removing anything.
    Why try it
    Recycles glutathione and vitamins C and E, supporting the antioxidant system rather than removing anything.
    Dose or use
    Follow product labelling, often away from meals.
    Time to results
    Typically 4-8 weeks
    Key study
    Traditionally used for antioxidant and detox support; this specific use for microplastic exposure has not been confirmed in controlled clinical trials.
    Caution
    Can lower blood sugar, which matters if you take diabetes medication. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  3. Curcumin

    Centuries of traditional use· Limited human trials so far (Evidence grade D · Traditional use long-standing)Long-standing traditional staple

    Anti-inflammatory antioxidant support

    Why it may be relevant
    Antioxidant and anti-inflammatory, aimed at the cellular stress attributed to a continuous low-level load.
    Why try it
    Antioxidant and anti-inflammatory, aimed at the cellular stress attributed to a continuous low-level load.
    Dose or use
    Follow product labelling; absorption is poor without piperine or a lipid.
    Time to results
    Typically 4–8 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Interacts with anticoagulants and can irritate the stomach at higher doses. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.

  4. Glutathione

    Looked, and found nothing conclusive· We reviewed the research for this use and found nothing that justified a grade (Evidence reviewed, no grade justified · No traditional record)

    Master antioxidant for cellular defense

    Why it may be relevant
    Taken in the hope of topping up the body's main antioxidant directly.
    Why try it
    Taken in the hope of topping up the body's main antioxidant directly.
    Dose or use
    Follow product labelling.
    Time to results
    Typically 4–8 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Oral glutathione's own absorption is contested, so this is the weakest route to a pathway NAC reaches more reliably. There is no clinical test for microplastic burden and nothing clears what is already there, so everything here is about reducing what you take in.
