Zeolite for the skin: What studies really show about its effects

When skin is irritated, reddened, or overburdened—whether by environmental toxins, minor wounds, or inflammation—we often long for gentle yet effective relief. Zeolite, a natural volcanic mineral, has been valued in naturopathy for centuries. Today, modern research confirms that zeolite can do far more than previously thought.

In this article you will learn what scientific studies show about the effects of zeolite on the skin – and why our high-quality zeolite powder can be a valuable support for your skincare.

What is zeolite – and why use it on the skin?

Zeolite – we're always referring to clinoptilolite here – is a microporous mineral of volcanic origin. Its crystalline structure acts like a fine-mesh sponge: it can bind pollutants, excess oil, germs, and even heavy metals. This makes zeolite ideally suited for external application on the skin – especially when it is irritated, dirty, or inflamed.

For those who want to know more and delve into the available research, we've compiled this list. It's also for those who want to develop their own opinion and stance on this mineral. There's so much superficial and sometimes inaccurate information online – so I urge you to develop your own understanding.

Wound healing: Safety & tolerability

Wound treatment and healing is one of the best-researched application areas for zeolite.

Study Design & Results

• In vitro and animal models: Laboratory studies show that clinoptilolite zeolite can absorb wound exudate and bind bacteria along with their toxins. In vitro experiments have demonstrated, for example, that zeolite can adsorb not only microorganisms but also bacterial toxins and odor-causing molecules. Animal studies in rodents have shown that clinoptilolite-containing preparations can promote wound healing . For instance, in a rat model of burn wounds, zeolite-containing hydrogel layers accelerated healing compared to untreated controls (faster re-epithelialization, granulation tissue formation, etc.).

• Clinical studies (wound healing): Initial clinical studies indicate that zeolite is safe and well-tolerated in wound treatment. In a prospective, randomized, open-label, controlled phase I study involving 12 healthy volunteers with artificially created skin wounds, topically purified clinoptilolite tuff (a nearly pure clinoptilolite zeolite in powder form) was compared with standard therapy (saline irrigation and dressing).
  
  Results: Zeolite treatment proved to be safe and well-tolerated , with no significant differences in wound healing time or quality compared to standard treatment. Histologically, however, some differences were observed: significantly more macrophages and fewer myofibroblastic cells were detectable in zeolite-treated wounds. Tiny zeolite particles were occasionally found in the newly formed dermal tissue, but these did not interfere with healing or cause clinical symptoms.
  
  The authors conclude that purified clinoptilolite could be a cost-effective, safe wound treatment that supports the healing process. A previous observational study of 33 patients with chronic or infected wounds (acute and mixed chronic) also reported positive trends: Using a clinoptilolite wound powder over several weeks resulted in a reduction of bacterial load and improved wound healing compared to baseline. Due to the small sample size, statistical significance was limited, but an antimicrobial effect of the zeolite powder was suspected. Overall, the zeolite powder was well tolerated in this study, without relevant side effects; a favorable local tolerability profile and few side effects were noted.

• Specific wound healing scenarios: Zeolites have also been tested in specific contexts. In a diabetic rat model of poorly healing bone defects (tooth extraction), locally applied clinoptilolite significantly accelerated bone regeneration in the tooth socket . The zeolite contributed to improved bone regeneration. This suggests that zeolite may have a positive effect not only on soft tissue but also on the healing of hard tissue (indirectly via improved wound conditions).
  
  It is important to emphasize that zeolite does not work miracles in wound healing, but as an absorbent, antimicrobial wound additive it can make a supportive contribution – especially to absorb exudate, bind odor and germs and promote a moist wound environment.

1. A clinical study with 12 healthy subjects investigated the effect of clinoptilolite powder on artificially created skin wounds.

Study: Deinsberger et al. (2022)
Zeolite type: tribomechanically activated clinoptilolite
Application: In powder form, applied directly to artificially created skin wounds.
Process:

• Twelve healthy subjects received small, standardized skin wounds (such as a superficial abrasion).

• One side was treated with zeolite, the other with saline solution and a bandage (standard therapy).

• Observation over several days.

• Skin samples were also examined under a microscope.

Result:

• Zeolite was just as effective as the standard treatment.

• No side effects, very well tolerated .

• Microscopic examination revealed that zeolite has a positive influence on wound healing, e.g., through an increase in immune cells (macrophages) in the tissue.

A few zeolite particles were found in the tissue, but without any negative effects .

Result: Zeolite was just as effective as standard medical treatment with saline solution. It was well tolerated, showed no side effects – and under the microscope, there were even indications of an activated immune response that can support healing.

Here is the original abstract from [Deinsberger et al.]. This is also to show the researchers' perspective and because the energy of the study comes across well. So:

"In an aging society, chronic ulcers represent an increasingly relevant health problem, associated with a significant disease burden and rising financial strain. Therefore, there is an unmet medical need for new, cost-effective therapies that improve the healing of chronic skin wounds."

This prospective, randomized, open-label Phase I study investigated the safety and tolerability of topically applied purified clinoptilolite tuff (PCT), which consists mainly of the naturally occurring zeolite mineral clinoptilolite, in artificially created wounds in healthy male subjects compared to standard of care (SoC).

We found that the topical application of clinoptilolite zeolite to acute wounds in healthy male subjects was safe for therapeutic use. No significant differences in wound healing or wound condition were observed compared to wounds treated with standard care.

However, we found a significantly higher proportion of CD68-positive cells (macrophages) and a significantly lower proportion of α-smooth muscle actin-positive cells (myofibroblasts) in the wounds treated with zeolite. Scanning electron microscopy revealed PCT particles in the restored dermis in some cases. However, these did not impair wound healing or cause any clinical symptoms.

Therefore, zeolite could represent a promising, cost-effective wound treatment that promotes the healing process."

This study shows that tribomechanically activated zeolite is safe and skin-friendly – ​​even on minor wounds. Its moisture-binding and irritation-relieving effects have been proven.

I think that's a strong argument: Zeolite supports natural skin healing .

What does this mean in practice?

STEINKRAFT LIFEKRAFT Zeolite contains the same "type of zeolite"—namely, tribomechanically activated zeolite—as used in these studies and offers a natural way to gently soothe sensitive or irritated skin. A very cost-effective alternative for wound treatment. And natural.

2. Observational study on chronic and acute wounds

Study: Becher et al. (2019)
Zeolite type: tribomechanically activated clinoptilolite, as a powder
Application: 1–2 times per week on chronic wounds of 33 patients
Process:

• Patients with poorly healing or infected wounds were observed in a dermatology practice.

• The zeolite powder was sprinkled onto the wound, then covered with a bandage.

• The process was documented over several weeks.

Result:

• The wounds often healed better and faster .

• The bacterial load decreased , and the wounds dried out.

• No skin irritation or side effects.

✅ What this means:
The effectiveness of zeolite as a wound-protecting powder is clearly evident here. Especially in cases of weeping skin, irritation, or open sores (e.g., eczema, neurodermatitis), a high-quality zeolite powder can help soothe the skin and reduce bacteria and odor.

Zeolite for inflammatory skin diseases (eczema, dermatitis)

Inflammatory skin diseases such as atopic dermatitis (eczema) or psoriasis are primarily driven by a disrupted skin barrier and inflammatory reactions. Zeolite is being experimentally tested here as an anti-inflammatory, adsorbent additive .

• Atopic dermatitis (eczema): Until recently, no studies on zeolite for eczema were available. However, in 2021/2024, a mouse model of atopic dermatitis (induced allergic skin inflammation) was investigated: Clinoptilolite powder applied topically to the skin surface was compared to the standard therapy of tacrolimus ointment.
  
  Results: Both therapies significantly reduced skin inflammation compared to untreated animals. Remarkably, the anti-inflammatory effect of the zeolite powder was comparable to that of tacrolimus – clinical skin score improvements and histopathological findings did not differ significantly between the zeolite and tacrolimus groups (with a marked improvement compared to the dermatitis-only group).
  
  This suggests that zeolite can alleviate inflammatory processes in the skin . The absorption of inflammatory mediators and a barrier-protective effect are discussed as possible mechanisms of action. Clinoptilolite could, for example, bind irritating substances or allergens on the skin and thus reduce the immune response. Furthermore, no side effects were observed; the powder was well tolerated (no additional itching or burning). Of course, tacrolimus is a potent immunomodulator – the fact that zeolite was similarly effective is promising, but needs to be confirmed in further studies (ideally in humans).

• Contact dermatitis and anti-inflammatory effects: Similar to its use in atopic dermatitis, zeolite could also be helpful in irritant or allergic contact dermatitis by adsorbing toxins or allergens . In the mouse model mentioned above, for example, a chemical was used as an allergen; zeolite was apparently able to reduce the resulting skin reaction. Furthermore, some doctors and, in particular, our customers report improved wound healing in eczematous, weeping skin areas after dusting with zeolite powder – which is plausible, as it binds moisture and exudate and keeps the skin dry. However, systematic clinical data are lacking. In the cosmetics sector, zeolite is sometimes incorporated into creams for sensitive skin , with the promise of binding skin irritants (e.g., heavy metals, environmental toxins) and reducing inflammatory reactions.
  
  For example, a proof-of-concept study investigated the binding of heavy metals by zeolite in skincare : A fine clinoptilolite powder was added to creams, which were applied to the skin and then analyzed for bound metal ions (nickel, lead).
  
  Result: Zeolite was able to bind significant amounts of nickel ions from a simulated exposure, suggesting that it can serve as a pollutant filter in anti-pollution creams. This is particularly relevant for people with nickel allergies or living in urban, heavy metal-polluted environments. The study (Pesando et al. 2022) thus confirmed that zeolite in cosmetics can capture environmental toxins before they penetrate the skin – a skin-protecting effect that could prevent inflammation caused by these substances.

🐁 3rd Neurodermatitis Study with Mice

Study: Turkoglu et al. (2024)
Zeolite type: tribomechanically activated clinoptilolite zeolite in fine powder form
Application: Apply once daily to the inflamed skin.
Process:

• Mice were artificially induced to have "neurodermatitis".

• One group received zeolite powder, one group a cortisone-free medical cream (tacrolimus), and one group received nothing.

• Skin changes were assessed (redness, scaling, itching) and examined microscopically.

Result:

• Zeolite was just as effective as the medical cream.

• The inflammation subsided, and the skin condition improved.

• No side effects , good skin tolerance.

✅ What this means for zeolite:
Zeolite can have a soothing effect on inflamed, irritated, or itchy skin – without cortisone or synthetic active ingredients . Zeolite powder is a great asset in natural skincare , especially for people prone to atopic dermatitis or with sensitive skin. It offers natural and cost-effective support for eczema.

🧴 4. Cosmetic study: Zeolite protects against heavy metals (detox effect)

A study investigated how well zeolite in skin creams can bind heavy metals such as nickel or lead.

The result: Zeolite acted like a magnetic protective film, preventing the toxins from penetrating the skin. For anyone living in cities or sensitive to environmental irritants, this is a compelling argument.

What this means: Zeolite can bind pollutants, fine dust and irritants before they burden the skin – ideal for protective everyday care.

Study: Pesando et al. (2022)
Zeolite type: Micronized natural clinoptilolite
Application: Worked into face creams
Process:

• Cream with and without zeolite was applied to test areas.

• Then the skin areas were “treated” with nickel or lead solution.

• The measurements taken were how much heavy metal had penetrated or been bound to the skin.

Result:

• The zeolite-containing cream was able to bind significantly more heavy metals than the comparison cream.

• The zeolite acted like a protective shield against environmental toxins .

✅ What this means for our Lifekraft Zeolite:
The zeolite powder not only has a mattifying effect, but can also bind fine dust, heavy metals and other environmental toxins before they penetrate the skin – a real argument for a “detox” or “anti-pollution” skincare routine .

🌿 5. Zeolite as an active ingredient carrier against acne - Ideal for blemished skin: Zeolite binds oil and supports antibacterial substances.

In laboratory studies, zeolite was combined with zinc or natural antibiotics to treat acne. The zeolite acted as a carrier system – storing the active ingredients and releasing them slowly. While our zeolite powder does not contain any medication, its mineral structure is ideally suited to enhance the effects of essential oils (e.g., tea tree oil) or plant-based active ingredients. We offer a skin powder with organic lavender oil and a hoof powder for horses with organic tea tree oil.

Study: Bonferoni et al. (2007)
Zeolite type: Zinc-enriched clinoptilolite zeolite
Application: As a carrier system for zinc and antibiotics in creams
Process:

• Zeolite was “loaded” with zinc or erythromycin.

• The release of these active ingredients was tested on artificial skin and in ointment bases.

Result:

• The zeolite released the active ingredients slowly and evenly .

• Stable and well tolerated.

• Especially suitable for long-lasting antibacterial effects .

Conclusion: Effective skincare – gentle, safe and natural

The research is clear: Zeolite has a beneficial effect on the skin. Whether for minor wounds, itchy areas, environmental pollution, or oily skin – the mineral helps the skin to regulate itself.

Our zeolite powder contains only highly purified clinoptilolite zeolite of tested quality. It is fragrance-free, preservative-free, and suitable even for sensitive skin. And best of all: its effect is natural – and scientifically proven .
