Fragrance-Free Day Switzerland
Fragrances are part of our everyday lives for example in cosmetics, washing and cleaning products. However, many people are unaware that at least 20% of the Swiss population is sensitised to at least one contact allergen. Fragrances are often involved and can trigger contact allergies and irritation.
Fragrance-Free Day will take place for the first time on 1 February 2026 and is being launched jointly by aha! Allergy Centre Switzerland and Service Allergie Suisse. It draws attention to the health effects of fragrances and gives advice on choosing fragrance-free products.
When buying cosmetics, detergents, or cleaning products, look out for products with the Allergy Seal of Quality. This seal confirms that the products have been rigorously tested and are suitable for sensitive skin. Find your products.
