The eternal charm of mud: from Cleopatra to modern spas

They say the first “mud-addicted” person was none other than Cleopatra: the beautiful queen of Egypt loved the mud baths of the Dead Sea, rich in minerals and with rebalancing properties for the skin. But the use of mud for healing and cosmetic purposes has much older and more widespread roots.

Already in Mesopotamian civilizations and in ancient India, mud was used in purifying rituals or mixed with medicinal herbs to restore the body’s balance. The Greeks spoke of it as a natural remedy to fight pain and inflammation, while the Romans made it one of the stars of their famous thermae: clay wraps, silt baths and body treatments were an integral part of the thermal routine, not only for therapeutic purposes but also as moments of socializing and pleasure. After a period of oblivion, it was in the Renaissance that the art of mud resurfaced in Italian thermal centers, where doctors and aristocrats rediscovered its virtues and regulated its use for targeted treatments, especially in the rheumatic and dermatological fields.

Today, centuries later, mud is back in the spotlight in a new guise, scientifically enhanced and formulated to meet different needs: aesthetic, functional, sensorial.

Hot or cold mud? Two allies against cellulite

Known for their draining, smoothing and toning action, today mud-based treatments are renewed thanks to new formulations, enhanced actives and production technologies that improve their effectiveness, safety and sustainability. No longer products reserved only for spa-goers, cosmetic muds are real concentrates of functional ingredients and natural actives capable of acting on multiple fronts: they fight cellulite blemishes, promote circulation, purify the skin and stimulate regeneration.

Depending on the desired effect and the application method, muds are divided into two categories: hot and cold. Hot muds exploit vasodilation to reactivate microcirculation and make the treatment deeper. They are ideal for colder months or in the presence of particularly rigid or congested tissues. Cold muds, on the other hand, act with a vasoconstrictor effect: they refresh, deflate and provide an immediate sensation of lightness. They are particularly recommended in summer or for those with capillary fragility. The current trend is to develop personalized formulas and “smart hybrids”, which combine warming and cooling effects for a targeted, progressive and customized treatment.

Not all products, however, are suitable for every skin type or condition. Some anti-cellulite muds, especially those containing iodine or L-thyroxine, are not recommended for people with thyroid disorders. L-thyroxine is a synthetic substance very similar to the T4 hormone, used in some formulations to stimulate local metabolism, but it can interfere with hypothyroidism therapies or worsen hyperthyroid states. There are, however, alternative formulations on the market specifically designed for these conditions. Also beware in case of fragile capillaries or venous disorders: hot muds, in particular, can accentuate vessel dilation. In such cases, it’s preferable to choose products designed for sensitive skin or with compromised microcirculation. It’s important to avoid use during pregnancy and breastfeeding, especially if the formula contains algae, iodine or hormonal derivatives. In any case, a doctor’s advice is always recommended.

New formulas, same ritual: muds become smart and sustainable

Innovations in the sector go beyond temperature or functional actives. The new generations of anti-cellulite muds focus on natural ingredients such as clays, thermal muds, mineral salts, botanical extracts and essential oils. Among the most used are centella asiatica, known for its effect on microcirculation, caffeine, green clay, and algae such as fucus, which effectively counteract water retention. The textures are becoming more modern: light, creamy or gel-based, easy to apply and often without the need for rinsing. Designed for those who seek practicality without compromising results, they can be combined with serums, boosters or massage treatments to enhance effectiveness.

Behind the scenes of production: how a modern cosmetic mud is born

Behind the velvety texture and evolved formulations of the new cosmetic muds lies a complex production process, requiring precision, flexibility, and technologies suited to the management of dense products rich in actives. The mixing of ingredients — clays, mineral salts, plant extracts and essential oils — often takes place at controlled temperatures to preserve their functional properties. In this phase, it is essential to ensure the homogeneity of the mixture and proper dispersion of active ingredients.

Dosing and filling, in particular, require machinery capable of handling high viscosities without altering the product structure. For this reason, cosmetic companies rely on specific systems for pasty and semi-dense products, equipped with anti-drip valves, volumetric dosers, even with electronic control that ensures precision, repeatability and hygiene. Packaging is evolving as well: from classic plastic or glass jars to heat-sealed tubes with caps, ideal for “ready to use” creams and masks, to preformed flexible pouches with single-dose muds or preparations for individual treatments. Each format requires dedicated equipment capable of handling dense and sometimes abrasive products, ensuring dosing precision, hygiene, and compatibility with different materials. Depending on the formulation and sales channel, packaging can be designed to ease application, extend shelf life or reduce environmental impact. In any case, the choice of container requires reliable and versatile filling systems, capable of adapting to multiple solutions efficiently.

Green cosmetics, smart processes: the sustainability challenge starts with production

The future of cosmetics also passes through conscious choices in the production phase. More and more companies, in fact, are investing in plants and technical solutions that allow for waste reduction, cycle optimization, and lower environmental impact. Modern dosing systems, for example, make it possible to work cleanly and precisely, minimizing product losses and simplifying cleaning operations.

Technologies designed to reduce energy consumption, heat only where necessary, and integrate recyclable materials in packaging are now a competitive advantage for those wanting to offer green cosmetics without compromising quality. Sustainability attention doesn’t stop at formulation: it begins in the heart of production.
