Stop 24

Stop 24 is a Nordic over-the-counter antiperspirant brand sold through pharmacies, focused specifically on managing excessive sweating. Its products are published by Karo Healthcare AS, the Norwegian arm of the Swedish consumer-health company Karo Healthcare AB, based in Stockholm [1]. The brand's consumer-facing presence is Norwegian, run through the site stop24.no, and its products remain in active pharmacy distribution across Norway.

The brand's corporate origin and its market presence sit in two different countries. The Stockholm registration and copyright on its own site point to Swedish ownership, while the public-facing brand — a Norwegian-language site and pharmacy listings — is Norwegian [1][2]. The country of origin is recorded as Sweden on the basis of ownership, though the brand operates chiefly in the Norwegian market.

Stop 24 is owned by Karo Healthcare, a Stockholm-based consumer-health company. The brand's site is copyrighted to Karo Healthcare AS and names the parent as Karo Healthcare AB, registered in Stockholm [1]. Stop 24 does not appear on Karo Healthcare's global "Our Brands" roster, which lists names such as E45, Locobase and CCS; it sits among the company's smaller regional pharmacy brands rather than its international portfolio [5]. Apobase and Decubal are sister brands under the same owner.

No founding year for the Stop 24 brand itself has been published, and no founders are named on the brand's site or in the sources reviewed.

The range centres on three products aimed at different needs: a roll-on, a cream and a stronger variant marketed as Stop 24 Strong. According to the company, the Strong product is "the strongest antiperspirant in the Nordics" and is intended mainly for underarm use [4]. The Roll-on is described as a highly effective treatment for sweating, while the Cream is meant for wider use across the body — excluding the eye area and mucous membranes — and is suited to skin folds.

The active ingredient is aluminium chloride, and the brand describes the series as using a combination of aluminium salts that reduce sweat-gland activity locally [3]. The company presents the products as fragrance-neutral and paraben-free [4]. It positions the line as taking sweat problems seriously, with a tagline that translates as "stops bothersome sweat," and states that the range was developed together with researchers and doctors [2]. Usage guidance on the site notes that the effect builds after roughly four to five days of use, with the product applied in the evening and washed off the next morning.

The brand is distributed through Norwegian pharmacy chains, including Apotek1, Vitusapotek, Boots and Apotera [2].

Stop 24 is active. As of 2026 its products are sold through major Norwegian pharmacy chains [6]. The brand's presence is single-country in practice — a Norwegian-language site and Norwegian pharmacy distribution — though it is also listed as sold in Sweden. Its aluminium concentration is not published on the brand's site, and no independent editorial coverage or Wikipedia entry exists, which is typical for a small pharmacy-channel product outside the beauty-editorial mainstream.
