Our Story

About Bionsen

Bionsen takes its inspiration from Japan.

Bionsen takes its inspiration from Japan. Natural thermal springs, called onsens, occur throughout Japan. Often based in beautiful natural surroundings, they are havens of peace, and a place of ritual relaxation. Many of the thermal springs are rich in important mineral, or ‘bio-elements’, which have proved important in skin well-being.


enhances the skin's protective barrier


promotes production of melanin, elastin and collagen


prolongs cell life


promotes growth and immunity

The name Bionsen comes from these two elements:

Bio – short for bio-elements
Onsen – Japanese thermal springs

Thermal Trace

For centuries the Japanese have recognised the health-giving properties of the minerals found in natural thermal springs.

The four main elements, that are also used in Bionsen, are
Calcium – enhances skins protective barrier
Copper – promotes production of melanin, elasten and collagen
Manganese – prolongs cell life
Zinc – promotes growth and immunity.

The Bionsen range

Bionsen has been around for 30 years.

In the UK it is best known for its deodorant range. Bionsen is the UK’s original % aluminium deodorant. In other countries Bionsen skin and body care is available as shower gel, bodywash, soap and now hand sanitiser. All contain the same Bionsen thermal minerals.

Sensitive Skin

All Bionsen products are dermatologically tested and hypoallergenic. This makes them perfect for even the most sensitive skin.

Deodorant vs Antiperspirant

A deodorant is not the same as an antiperspirant.

A deodorant is designed to combat odour. Whereas an antiperspirant is designed to block the pores that sweat comes from. The compound in antiperspirant that does this is Aluminium Chlorohydrate.

Sweating is a natural process, designed to cool the body down. However for a few people sweat can be excessive, and an antiperspirant would be appropriate.

For most people, in most situations, a deodorant like Bionsen is the better solution. Bionsen attacks the bacteria that cause under-arm odour, without blocking the pores.

Also antiperspirants do not work immediately, they take time for a gel layer to form in the under-arm area. If you want to feel fresh immediately use a deodorant.

0% Aluminium

Bionsen is aluminium free, because it is a deodorant, not an antiperspirant.

Many people actively choose a 0% aluminium deodorant because they have heard stories about an association between antiperspirants with aluminium and breast cancer. There is actually no hard scientific evidence to support this link.

Nevertheless some people do not want to take any risks, and we respect that.

Bionsen remains aluminium free because we believe, that for most people, it is the most effective way to care for your skin and to stay fresh.


Bionsen is not only aluminium-free. It is also free of parabens, silicones and colourants.

0% silicones - silicones form a coating on the skin, that act like a barrier to both water and air. A coating of silicones can make the skin feel temporarily smooth, but they are not actually doing anything beneficial. Plus they make not break down in the environment for hundreds of years. So Bionsen chooses not to use them.

0% colourants – there have been a number health concerns about particular artificial colourants. But really, are they necessary in a deodorant? Here at Bionsen we think it’s a easy decision – just avoid colourants full stop.

0% parabens - parabens are widely used within personal care products. They are used as a preservative and help stop bacteria, fungus and microbes from growing in creams and make-up. There are concerns that absorption of parabens into the body poses a potential health risk. For this reason Bionsen, like some other health & beauty brands, chooses not to use parabens.


Bionsen is an aluminium and paraben free deodorant with thermal spa minerals to help nourish and protect skin.
