Biotherm Deo Pure Roll-On Antiperspirant 75ml

Biotherm Deo Pure Roll-On Antiperspirant 75ml is a 48-hour antiperspirant from one of France's most respected dermatological skincare houses. The fluid, fast-drying formula glides on through a wide roller ball, leaving no sticky residue and no yellow or white marks on clothing — gentle enough to use straight after shaving and reliable enough for long days.

About Biotherm

Biotherm is a French skincare brand founded in 1952 by biologist Jeanine Marissal, recognised for its pioneering use of Life Plankton — a thermal plankton extract identified in the spring waters of Molitg-les-Bains in southern France. The Deo Pure line applies the same regenerative, skin-friendly philosophy to deodorant care, formulated to be effective without compromising on skin comfort.

Key benefits

• 48-hour antiperspirant protection
• Quick-drying formula — no sticky finish
• Helps prevent yellow or white marks on clothing
• Alcohol-free, suitable for sensitive skin
• Safe to use after shaving or hair removal
• Wide roller ball for fast, even application

Key ingredients

• Aluminium chlorohydrate — the active antiperspirant ingredient that helps reduce perspiration
• Biotech Plankton (Life Plankton derivative) — Biotherm's signature regenerative ingredient, enriched with minerals, amino acids and vitamins
• Dimethicone — provides a soft, comfortable glide
• Cetearyl alcohol — supports the smooth roll-on texture

Who it's for

Best for anyone wanting a reliable, long-wearing antiperspirant that prioritises skin comfort. Particularly well suited to sensitive skin, recently shaved underarms or anyone who reacts to alcohol-based aerosol deodorants. The wide roller and quick-drying finish make it equally good for daily home use, the gym bag and travel.

How to use

1. Apply to clean, dry underarms after showering — ideally before getting dressed.
2. Roll evenly two or three times across each underarm.
3. Allow a few seconds for the formula to dry before contact with clothing.
4. Reapply only if needed; one morning application typically lasts up to 48 hours.
