As the manufacturer of Yerka, we have been dealing with heavy sweating and the questions people affected have about it for generations. This includes the question of aluminium in deodorants and antiperspirants. Yerka contains aluminium chloride\u2014deliberately, because this active ingredient can effectively reduce sweat production. <\/p>\n\n

It\u2019s important to us to explain openly how aluminium salts work, what current research says, and what to watch out for when using them. Because a deodorant with aluminium isn\u2019t necessary for every purpose. However, if the issue is not only body odour but, above all, underarm wetness and heavy sweating, it offers a decisive advantage over a regular deodorant. <\/p>\n\n

How does a deodorant with aluminium work against sweat?<\/h2>\n\n

Strictly speaking, a deodorant with aluminium is usually an antiperspirant. While a classic deodorant is mainly intended to prevent unpleasant odour, an antiperspirant targets sweat production itself. <\/p>\n\n

Aluminium salts react with components of the skin in the sweat gland duct. This temporarily forms a gel-like complex that narrows or blocks some of the sweat ducts. As a result, less sweat reaches the skin\u2019s surface. <\/p>\n\n

The sweat glands are neither destroyed nor permanently switched off. When the complex dissolves again through the skin\u2019s natural renewal process, sweating increases again. That\u2019s why an aluminium-containing deodorant is used regularly depending on the product and individual needs. <\/p>\n\n

The effect remains limited to the treated area of skin. The body\u2019s natural temperature regulation continues to work via the many other sweat glands. In addition, less moisture can also limit the development of sweat odour. Fresh sweat is initially largely odourless. The typical smell mainly develops when skin bacteria break down components of sweat and skin secretions. <\/p>\n\n

At Yerka, we use aluminium chloride at a low active-ingredient concentration. The liquid form allows particularly economical, individual dosing: only a few drops are needed per application. You can find more information about the active ingredient in our guide to aluminium chloride deodorant<\/a>. <\/p>\n\n

How should aluminium be assessed from a health perspective?<\/h3>\n\n

Aluminium can harm the body in high amounts. What matters, however, is how much is actually absorbed. With cosmetic antiperspirants, current evidence suggests absorption through the skin is significantly lower than was assumed for a long time. <\/p>\n\n

After evaluating more recent human studies, the German Federal Institute for Risk Assessment concludes that, based on current scientific knowledge, health impairments from daily use of antiperspirants with aluminium chlorohydrate are unlikely. The EU\u2019s Scientific Committee on Consumer Safety also considers aluminium compounds safe within the concentrations studied. <\/p>\n\n

We don\u2019t want to draw either a blanket conclusion of \u201caluminium is always harmless\u201d or an unnecessary warning from this. The compound used, the amount of active ingredient, and correct use are all part of an objective assessment. In addition, aluminium salts can irritate the skin locally, even if no relevant health risk is expected from absorption through the skin.

Who is aluminium-containing deodorant especially suitable for?<\/h2>\n\n

A deodorant with aluminium is primarily suitable for people who want to reduce not only odour but also the amount of sweat. This can be helpful with heavy sweating, visible sweat stains, summer heat, physical exertion, stress, or hormonal changes. <\/p>\n\n

People with localized excessive sweating under the arms\u2014and, depending on the product, on the hands or feet\u2014can also benefit from an antiperspirant. Yerka was developed specifically for people who suffer from heavy sweating, underarm wetness, or unpleasant sweat odour and don\u2019t achieve sufficient results with a regular deodorant. <\/p>\n\n

If, on the other hand, you sweat normally and mainly want to limit odour formation, you don\u2019t necessarily need a sweat-inhibiting active ingredient. In this case, a regular deodorant may be sufficient. <\/p>\n\n

Sudden-onset sweating, night sweats, or sweating that affects the whole body should be medically evaluated. This is especially true if additional symptoms such as a racing heart, fever, trembling, or unexplained weight loss occur. <\/p>\n\n

Which brands and products contain aluminium?<\/h2>\n\n

Aluminium salts are found in many products labelled as antiperspirant, anti-transpirant, or anti-perspirant. Some products that are simply labelled \u201cdeodorant\u201d also contain sweat-inhibiting active ingredients. The ingredients list on the packaging is therefore the most reliable source of information. <\/p>\n\n
