Louis Widmer Deo Roll-On 0% Parfum is a fragrance-free, alcohol-free antiperspirant from the Swiss dermatological brand Louis Widmer, formulated to deliver reliable 24-hour sweat and odour protection on even the most sensitive, easily irritated skin. This 50ml roll-on uses aluminium chlorohydrate to regulate excessive perspiration while staying gentle enough for daily use under the arms and on the hands and feet, a genuinely useful quality in the heat and humidity of the UAE.

Why This Deodorant Works

Sweat itself is odourless. Body odour develops when skin bacteria break down perspiration, so effective protection has to address both. Aluminium chlorohydrate temporarily reduces the flow of sweat, while odour-neutralising actives limit the bacteria responsible for smell. Because the formula leaves out alcohol and perfume, it avoids the two most common triggers of stinging and irritation, so 24-hour freshness is achievable without discomfort.

Ideal For

This 0% Parfum roll-on suits anyone whose skin reacts to fragranced or alcohol-based deodorants, including sensitive, reactive, or allergy-prone skin. It is a practical choice for people managing excess perspiration on the underarms, hands, or feet, and for those who simply prefer a completely unscented option. It is identical in strength to the scented version, trading only the perfume, not the performance.

Every Louis Widmer deodorant is built on a short, skin-compatible ingredient list. The actives doing the work in this roll-on include:

• Aluminium Chlorohydrate: reduces excessive perspiration by temporarily minimising sweat gland activity, the core of the 24-hour antiperspirant effect.

• Ethylhexylglycerin: inhibits the odour-causing bacteria that develop on skin, keeping you fresher for longer.

• Chitosan: a marine-derived active used in the Deo Roll-on to help soothe and support skin comfort.

• Allantoin: a well-recognised soothing agent that helps calm and protect delicate underarm skin.

1. Apply once daily to clean, dry skin, ideally after showering.

2. Roll a thin, even layer onto the underarms, or onto the hands and feet where needed.

3. Allow a few moments to dry before dressing.

For heavy sweating or hyperhidrosis, apply morning and evening. The full antiperspirant effect builds over the first 2 to 3 days of regular use, so give it a little time before judging the results. A thin layer is enough, so there is no need to over-apply.
