4 ingredients in a deodorant that won’t work on sensitive skin


HIs alcohol, triclosan and other components in the composition of deodorants and antiperspirants dangerous? Dermatovenereologist Nina Sergeeva (@dr_ninas) explains when it is worth abandoning an antiperspirant and how a stick differs from a roll-on product.


Alcohol is found in most deodorants and antiperspirants. It is used as an antibacterial agent (preservative), but it can also dry out the skin.

With constant use of an antiperspirant (especially on sensitive skin), alcohol causes severe dryness, a burning sensation and leads to an imbalance of microflora. To avoid further injury to your skin, do not use antiperspirant immediately after shaving or apply to the affected area.


This is another antimicrobial ingredient. In deodorants, it is used to stop the growth of bacteria that cause unpleasant odors.

There is research, which confirm that triclosan can accumulate in adipose tissue and turn into a more toxic substance. It, in turn, exhibits cytotoxic (damages the cells of the body), genotoxic (violates the integrity of the genetic material) properties and is capable of causing endocrine disorders. Many bacteria stopped responding on triclosan because of its ubiquitous use.

In 2016, the US Food and Drug Administration (FDA) banned the use of triclosan in soap products, but it is in other products (deodorants, toothpastes).

Aluminum salts

There is a lot of controversy around this component. Aluminum is toxic and can accumulate in the body, but no research has yet found a direct link between the use of antiperspirants with aluminum salts and an increased risk of cancer (accordingly, there are no scientific reviews to confirm this).

Its function as part of an antiperspirant is to block the sweat glands for a while so that no sweat is released. But with prolonged use of the agent with aluminum salts, clogging of the pores can occur, which, in turn, will cause inflammation of the ducts of the sweat glands – hydradenitis.

If you can’t completely stop using antiperspirant, on inactive days, use deodorants – products that block odor, not sweat (by link our rating of the best deodorants without aluminum salts).

Important: When using a roll-on antiperspirant, less aluminum penetrates the skin. Most of all – from the stick.

Di-, tri-ethanolamines (marked on packages as DEA, TEA)

These substances are responsible for regulating the pH in the antiperspirant. But with heavy use, it can cause irritation, increased dryness and allergic reactions. There is researchwhich confirm their carcinogenic properties. Ethanolamines are also found in hair dyes and soaps.
