Why don't dogs have smelly armpits

The wrong deodorant leads to more sweat odor

Dry armpits and a fresh scent - that's what a good deodorant should do. Various active ingredients are used for a strong effect. The skin defends itself against some. It can happen that the deodorant even increases the unpleasant smell of sweat.

Aluminum salts, fragrances, preservatives and alcohol: Many deodorants contain ingredients that can irritate and dry out the skin. If the skin loses its natural balance, it becomes more prone to inflammation. And not only that: bacteria feel particularly good on irritated skin. "If the defense mechanism of the skin is disturbed by the deodorant, bacteria have an easy job," says Dr. Uta Schlossberger, dermatologist from Cologne. "Then there can be an increased smell of sweat under the armpits - despite deodorant." In addition, dry armpit skin favors ingrown hair.

Aluminum deodorants constrict the sweat glands

In addition to alcohol and preservatives, aluminum salts in particular have a drying effect. "The aluminum allows the sweat glands to dry up in two ways. On the one hand, it ensures that the skin contracts so that the sweat ducts narrow. On the other hand, it forms a gel-like layer of proteins that, like a plug, exit the ducts for a while closes, "explains Schlossberger. "Therefore, aluminum can cause skin irritation and eczema on sensitive skin if it is used several times a day." The dermatologist advises avoiding aluminum if you get very dry and itchy armpits from it.

Sensitive skin? Avoid these fragrances in deodorants

According to Schlossberger, caution is also advised with fragrances. Many can trigger allergies, which can also manifest as redness, itching, oozing and burning. "Anyone who has already reacted to fragrances and cannot tolerate a deodorant should have individual substances tested by a dermatologist," she said. "Since natural essential oils also contain fragrance allergens, the allergy potential is also great here." According to the dermatologist Evernia Prunastri Extract (oak moss), isoeugenol (clove) and cinnamal (cinnamon) are particularly aggressive. On the other hand, amyl cinnamal (jasmine), citral (lemongrass) and butylphenyl methylpropional (lily) are well tolerated. The active ingredient farnesol, a flower alcohol with bacteriostatic properties, only rarely triggers fragrance allergies. If you want to be on the safe side, use perfume-free products.

Crude oil in deodorants leads to skin care

Oils help to strengthen the protection of the skin and make it more resilient. Deodorants with natural care ingredients such as almond, jojoba or avocado oil are a good choice, according to Schlossberger. Deodorants with petroleum are less suitable: "Cheap, swelling petrochemical substances, mostly made from petroleum, simulate the nourishing effect because they make the skin feel good. In reality, these compounds, which are declared as dimethicones, reduce the natural function of the skin."

Cancer-causing substances in deodorant

Caution is also advised with parabens. "As an estrogen-promoting substance, they can trigger cancer. Formaldehyde is also considered to be a cancer and allergy trigger," warns Schlossberger and adds: "Polyethylene glycols and PEG derivatives serve to create chemical bonds, but also make the skin more permeable and therefore less resistant to harmful substances. Sensitive people should use products that, if possible, get by without chemical emulsifiers. "

Sage gently inhibits the flow of sweat

Aluminum is also repeatedly discussed as a cause of cancer. If you want to do without the fabric but not on an antiperspirant effect, you can try sage. Drunk as tea, it can inhibit perspiration somewhat. Sage can also be found in many natural deodorants. "It is not yet known exactly which active substances inhibit the flow of sweat. However, it can be assumed that the essential oils contained calm the nerve endings of the sweat glands and thus inhibit sweat production," says Schlossberger.

A foot bath made from four tablespoons of dried sage leaves and one liter of hot water, for example, inhibits foot perspiration. "Cover your feet completely and bathe in the sage water for about 15 minutes. If you don't like the taste of sage tea, sage capsules from the pharmacy are an alternative."
