AHAVA research laboratory — Dead Sea water samples and glassware

AHAVA Patents

Over thirty-five years of Dead Sea science — protected, patented, proven.

Science of the Dead Sea

The only skincare lab at the lowest point on Earth.

AHAVA doesn't borrow Dead Sea minerals — we work on their shore. For over thirty-five years, our scientists have studied the only water on Earth with this mineral composition, and translated what they learned into cosmetic chemistry no one else can make.

The patents collected below are the formal record of that work. Each one is a problem we set out to solve — how to stabilize Dead Sea water at therapeutic concentration, how to deliver minerals through the stratum corneum, how to get Vitamin A benefits without the irritation — and each one sits behind a real AHAVA product on the shelf today.

Read them in order, and a picture comes into focus: the story of how Dead Sea science has evolved from raw mud compresses to stimuli-responsive nanocapsules, one problem at a time.

A Compress Comprising Mineral Mud — AHAVA patent illustration
1998#01

A Compress Comprising Mineral Mud

Dead Sea mud therapy — without the mess.

The idea was simple: take the same mineral-rich silt that draws visitors to the Dead Sea every year, and make it something you can use at home — cleanly, repeatably, with no splash or spill. The solution took shape as a multi-layer compress: a porous fibrous cloth against the skin, a highly absorbent middle layer holding mud evenly distributed, and a non-permeable backing that keeps everything where it belongs. Engineered to be thermostable, it can be heated and reheated without breaking down, even under the extreme salinity of real Dead Sea water. When worn, minerals diffuse into the epidermis through steady osmotic pressure — the same mechanism that makes the Dead Sea a destination, delivered at home.

For youA self-administered spa-grade mud treatment that leaves no mineral residue to clean up.

Liquid Salt Composition — AHAVA patent illustration
1999#02

Liquid Salt Composition

Dead Sea water at its highest-ever concentration, stabilized as a clear gel.

Suspending the full ionic load of the Dead Sea in a wearable product is a stability problem — high ionic strength tends to break emulsions apart. We solved it with specific natural gelling agents and nonionic solubilizers that hold the mineral matrix in a clear, hydrophilic gel. The same matrix suspends nourishing vegetable oils, fatty acids, and vitamins alongside the hygroscopic minerals. What this does at the skin level: alters the concentration cascade at the stratum corneum, so magnesium, calcium, and potassium ions cross the barrier more efficiently than from a conventional moisturizer. The result is a prolonged, non-irritating delivery of Dead Sea chemistry at therapeutic concentration.

For youDeeper mineral penetration than a standard cream, for long-lasting intracellular hydration and reinforced barrier function.

Skin Care and Protection Composition (3Dcomplex™) — AHAVA patent illustration
2001#03

Skin Care and Protection Composition (3Dcomplex™)

Minerals meet plants that evolved to survive where almost nothing else does.

3Dcomplex™ was our first deliberate pairing of Dead Sea water with extremophile botanicals. We combined our mineral extract with Dunaliella salina (an algae that thrives in hyper-saline water), fenugreek, and Zizyphus — three plants shaped by environmental stress — then stabilized the blend with Sclerotium Gum and emollients like cetyl alcohol and octyl palmitate. The pairing isn't incidental: plants that survive stress tend to concentrate compounds that help skin survive stress too. Broad-spectrum by design, 3Dcomplex™ both hydrates the epidermis and shields it from UV and environmental damage, and actively stimulates cell renewal.

For youAnti-aging protection that borrows resilience from organisms already proven to thrive under pressure.

Cream Composition Comprising Dead Sea Mud (Dermud™) — AHAVA patent illustration
2003#04

Cream Composition Comprising Dead Sea Mud (Dermud™)

Dead Sea silt in a leave-on cream for the first time.

Raw Dead Sea mud is restorative but impractical — messy, textured, hard to incorporate into daily use. Dermud™ emerged from the challenge of making it wearable: a stable oil-in-water emulsion that holds heavy mineral silt without separating, built on a precisely balanced lipophilic phase and glycerin-based hydration. We layered in allantoin, aloe, Vitamin E, and zinc oxide — anti-irritants chosen specifically for compromised, reactive skin. A high-shear homogenization process gives the final texture a smooth, non-grainy feel while preserving the mineral payload. Every application continues to deliver hygroscopic minerals into the epidermis, repairing the barrier on contact.

For youThe therapeutic benefit of raw Dead Sea mud in a cream you can actually use every day, including on sensitive skin.

Personalized Skin Care Composition — AHAVA patent illustration
2008#05

Personalized Skin Care Composition

Precision skincare, formulated from your own cellular data.

Long before "personalization" became a buzzword in beauty, we were exploring what it could actually mean scientifically. The method: sample the epidermis non-invasively, test for biomarkers tied to cellular aging, renewal, and inflammation, and match the resulting profile against a reference database. From there, a custom cosmetic is formulated with exactly the active ingredients and mineral ratios an individual's cellular metabolism is asking for — whether the target is premature aging, chronic dryness, breakouts, or sensitivity. It's skincare built from the biology up, not picked from a shelf of generic formulas.

For youThe principle behind truly individualized skincare, where the formula follows your cells — not the other way around.

Anti-Inflammatory Cosmetic Composition — AHAVA patent illustration
2009#06

Anti-Inflammatory Cosmetic Composition

Dead Sea chemistry, engineered specifically for distressed skin.

Dryness, itching, peeling, and tightness often signal inflammation the skin can't resolve on its own. This composition was developed for exactly that state — a targeted anti-inflammatory matrix that uses the osmotic and ionic properties of Dead Sea water to calm reactive epidermis. High-concentration magnesium, calcium, and potassium combine synergistically with soothing botanical extracts and emollients; together they replenish depleted intracellular moisture while measurably reducing inflammatory markers. Designed for long-lasting comfort without steroid or drug chemistry, the formulation rebuilds the epidermal barrier while actively relieving the discomfort that comes with its breakdown.

For youRelief from dryness and tightness that goes after the inflammation beneath it, not just the symptoms on top.

Mineral Cleansing Creams — AHAVA patent illustration
2009#07

Mineral Cleansing Creams

A cleanser that purifies without stripping — delivering minerals even as it washes away impurities.

Most cleansers have a trade-off: effective cleaning usually means stripping the barrier. This one was built to avoid that. The challenge was emulsion stability: high-ionic-strength water wants to destabilize surfactants, so we engineered a structured surfactant system that holds vegetable and volatile oils in balance with the mineral payload. Through careful phase homogenization, the resulting emulsion dissolves impurities and sebum but simultaneously delivers magnesium, calcium, and potassium ions into the epidermis. The lipid barrier is left intact; nothing feels tight, nothing feels stripped, and the skin ends the wash hydrated rather than depleted.

For youThe rare cleanser that leaves your skin more nourished than it found it.

Extreme Skin-Care Composition — AHAVA patent illustration
2010#08

Extreme Skin-Care Composition

The lowest point on Earth meets the highest.

Two of the harshest environments on the planet — the Dead Sea basin and the Himalayas — produce life forms with unusual biochemical defenses. This composition combines them: our Dead Sea extract paired with Himalayan Raspberry, Goji Berry, and Iceland Moss. The synergy isn't poetic — it's measurable. Plant extracts from extreme altitude concentrate antioxidants and protective compounds; combined with hyper-saline mineral water, they form an active matrix that defends against environmental stressors and supports cellular rejuvenation more effectively than either input alone. The result is a formulation that treats aging as primarily an environmental problem, and delivers the chemistry to meet it.

For youDaily protection that borrows resilience from plants and minerals already adapted to extreme stress.

Cosmetic Composition Containing Nano-Magnets — AHAVA patent illustration
2014#09

Cosmetic Composition Containing Nano-Magnets

Biocompatible nano-magnets as targeted dermal delivery vehicles.

Magnet therapy has a long history in physical medicine; the question we asked was whether it could improve dermal delivery in cosmetics. The answer came through engineering biocompatible nano-magnetic particles from soft ferrites like magnetite, then suspending them in hydrating emulsions alongside Dead Sea mud and bath salts. Applied as a mask, cream, or gel, the particles interact with the skin to stimulate microcirculation and enhance absorption of accompanying actives — Vitamin E, aloe, and the mineral payload itself. It's cutting-edge materials science applied to one of cosmetics' oldest problems: how to get actives through the stratum corneum and keep them working.

For youHigher active-ingredient absorption, so every application works harder than a conventional cream.

Beta Endorphin Stimulation — AHAVA patent illustration
2014#10

Beta Endorphin Stimulation

Dead Sea minerals stimulate the skin's own beta-endorphin production — for up to 48 hours.

One of our more unexpected findings: applying an optimal concentration of Dead Sea water topically triggers the skin to produce and sustain the release of beta-endorphin neuropeptides — the same class of molecules associated with stress relief and nervous-system regulation. The sustained-release profile we measured extended up to 48 hours per application. Beyond the subjective relaxation effect, these neuropeptides play a measurable physiological role: they modulate skin immune function, ease mechanical tension in the tissue, and reduce the inflammatory signaling that drives dryness and sensitivity. It's an early example of neuro-cosmetic science with a legitimate mechanistic basis.

For youA topical that measurably calms the skin's stress response, not just its surface.

Dead Sea Concentrated Osmoter™ & Green Tea — AHAVA patent illustration
2014#11

Dead Sea Concentrated Osmoter™ & Green Tea

The Concentrated Osmoter™ pairs with green tea catechins for dual-action defense.

Concentrating our signature Dead Sea water extract turns the minerals into an osmotic pump — actively drawing moisture to the epidermis, not just adding it. Pairing that pump with green tea extract was a deliberate choice: green tea's catechin polyphenols are among the most effective natural antioxidants available, and the mineral matrix was engineered to enhance their penetration and activity. The two work together rather than side-by-side: the mineral concentration drives the actives deeper; the antioxidants neutralize the free radicals that the minerals then help the skin withstand. Together, they dramatically reduce UV-induced photo-aging and soothe reactive inflammation.

For youTwo proven antioxidant systems working in concert — one drawing moisture, the other neutralizing damage.

Apple Of Sodom — AHAVA patent illustration
2020#12

Apple Of Sodom

A Dead Sea native plant, decoded without harvest.

The Apple of Sodom grows natively in the Dead Sea region and contains — along with useful compounds — a naturally occurring steroidal toxin called Calotropin. Traditional extraction methods couldn't separate the two cleanly, and harvesting from the wild wasn't sustainable either. Our approach used in-vitro biotechnology: we cultured Apple of Sodom callus cells from root explants, producing a pure aqueous extract with zero Calotropin and no ecological impact on the local flora. Paired with our Dead Sea mineral matrix, the extract influences critical cellular signaling pathways tied to the visible signs of aging — reducing deep wrinkles, calming environmental stress response, and restoring firmness.

For youBotanical anti-aging chemistry produced sustainably — no wild harvest, no toxic byproducts.

Crystal Osmoter — AHAVA patent illustration
2022#13

Crystal Osmoter

Stimuli-responsive nanocapsules release Dead Sea minerals only where the skin needs them.

The Crystal Osmoter is an oil-based dispersion of nano-sized Dead Sea material, encapsulated inside smart polymer nanocapsules we engineered to stay stable in a nourishing oil phase — and dissociate only in response to specific physiological triggers. The triggers are targeted: pH shifts, or the presence of enzymes associated with inflammation and compromised skin. When the skin is in that state, the capsules open and release a concentrated, hyper-saline burst of magnesium, calcium, and potassium exactly where the barrier needs repair. Healthy skin leaves them intact; distressed skin activates them automatically.

For youA moisturizer that becomes more active when your skin is more stressed — not less.

Osmoguard & Pollustop® — AHAVA patent illustration
2022#14

Osmoguard & Pollustop®

A two-layer shield against urban pollution — mechanical and biochemical.

Pollution damage to skin isn't one problem; it's two. Particulate matter causes mechanical deposition at the surface, while ozone and heavy metals cause biochemical oxidative stress beneath it. Osmoguard addresses both by combining our Dead Sea water extract with POLLUSTOP®, a biotechnologically derived anionic polysaccharide that forms a second-skin mechanical barrier. Our research showed that neither alone is enough to handle ozone-induced damage — the combination is. The resulting composition inhibits inflammatory marker secretion while the mineral matrix runs the intracellular signaling that prevents accelerated aging from daily pollutant exposure.

For youGenuine protection from city air — two defense layers where most "anti-pollution" creams have one.

Smartium (PeptiCaps) — AHAVA patent illustration
2022#15

Smartium (PeptiCaps)

Nanocapsules with peptide locks that only the skin's own biology can open.

Smartium builds on the encapsulated-delivery idea with a more selective trigger. The nanocarrier is an amphipathic polymer held together by a specific peptide linker — and the release mechanism is elegant: only pH shifts or specific degradation enzymes in stressed skin will cleave that peptide bond. Intact skin leaves the capsules alone; stressed skin opens them. What's released is a hyper-saline dose of magnesium, calcium, and potassium directed exactly where the barrier is breaking down. It's one of the most targeted mineral delivery systems we've developed — maximum therapeutic density, zero waste on healthy tissue.

For youActive ingredients that respond to your skin's condition in real time.

High Performance Nonwoven Fabrics — AHAVA patent illustration
2022#16

High Performance Nonwoven Fabrics

Dead Sea minerals embedded directly into skincare fabric.

Sheet masks, wipes, and dermatological patches are almost always a passive delivery format — a substrate holds an active, the active migrates to skin, the substrate is discarded. We wanted to make the fabric itself active. Using spunbond and meltblown textile technologies, we engineered nonwoven composites with Dead Sea mineral extract integrated directly into the filamentous material — either as a coating or impregnated through the fiber core. The result is a fabric that delivers magnesium, calcium, and potassium through direct or fluid-mediated skin contact, reducing irritation and sensitivity while calming the compromised barrier. The delivery vehicle becomes part of the treatment.

For youSheet masks and dermatological textiles where the fabric is the active, not the wrapper.

pRetinol™ — AHAVA patent illustration
2023#17

pRetinol™

The anti-aging benefits of Vitamin A — without the irritation.

Retinol works, but it often burns, peels, and sensitizes — which is why most people can't use it daily. pRetinol™ flips the mechanism: instead of applying synthetic retinol externally, the formulation supplies the precursors your skin cells need to produce retinoic acid themselves. The precursor matrix combines Dead Sea water extract, Dunaliella salina microalgae, and precise concentrations of β-carotene and Niacinamide. The skin synthesizes what it needs, at the rate it can tolerate — so you get wrinkle reduction and cellular renewal without the flare-ups that stop most retinol routines before they start.

For youVitamin A-level results with none of the burning, peeling, or sensitivity that usually comes with it.

Anti-Glycation Compositions (AGEs) — AHAVA patent illustration
2023#18

Anti-Glycation Compositions (AGEs)

Targeted defense against glycation — the sugar-protein damage most anti-aging products ignore.

Glycation is one of aging's quieter mechanisms: sugars bind to collagen and elastin, forming Advanced Glycation End-products (AGEs) that stiffen the proteins and degrade their function. Most anti-aging skincare doesn't address this pathway at all. Our triplex combines Dead Sea mineral extract with botanical extracts from the Myrrh tree and Milk Thistle, each chosen for documented glycation-inhibition activity. Testing on actual skin proteins showed this matrix measurably blocks AGE formation and neutralizes the oxidative stress that accelerates it. The visible consequence: the extracellular matrix stays supple, deep wrinkles are delayed, and the skin retains its elasticity longer.

For youTargeted defense against a specific aging mechanism that diet and most skincare never address.

Halobacteria — AHAVA patent illustration
2023#19

Halobacteria

A skin-resilience matrix built from microbes that thrive in Dead Sea brine.

Halobacteria are extremophile microorganisms native to the hyper-saline waters of the Dead Sea — genuine survivors of conditions that kill almost everything else. Using fermentation and osmotic-shock extraction, we produced a lysate exceptionally rich in natural squalene, skin-replenishing lipids, and sulfated proteoglycans. Paired with our mineral matrix, the lysate activates enzymes that cross-link and stabilize collagen and elastin while simultaneously suppressing the genetic pathways that degrade them. The combination reinforces the skin barrier, neutralizes oxidative stress, restores intracellular moisture, and improves firmness — borrowing survival chemistry from organisms that have already solved the problem.

For youCollagen support and elasticity derived from microbes that genuinely outlast their environment.

Osmoter™ Lucent-Boosting Complex — AHAVA patent illustration
2023#20

Osmoter™ Lucent-Boosting Complex

Multi-pathway brightening — without the irritation of conventional lighteners.

Traditional skin-brightening ingredients work mostly through tyrosinase inhibition, and most are irritating at effective concentrations. The Osmoter™ Lucent-boosting Complex uses a different approach: a tri-active matrix of our Dead Sea mineral water, Tyrostat™ 11 (a Rumex occidentalis extract), and Pureoxin™ (a plant-derived Thioredoxin-1 polypeptide). Together they act on multiple melanin-synthesis pathways at once, reducing pigment production and accumulation without pushing any single mechanism past its irritation threshold. The formulation neutralizes oxidative stress (a driver of hyperpigmentation), fades visible dark spots, and restores even tone — comfortably.

For youVisible brightening that works from multiple angles at once, without the sting of single-active lighteners.
