An innovative teeth whitening product, referred to here as an "instant teeth makeup," has gained significant popularity due to its visual results, which are highly suitable for platforms like TikTok and Instagram Reels. The product recently went viral, attaining millions of views for various TikTok videos. The business behind this product was launched in late 2025, and in its initial promotional phase during December 2025, achieved approximately €10,000 in sales with a 26% profit margin through paid advertisements. Following this, the owner shifted focus to another project and halted active advertising. From January to August 2026, all subscriptions were paused. However, in August 2026, the subscriptions were reactivated, resulting in about 70 active subscriptions that generate approximately €600 monthly in profit without any advertising investment. Over the past year, the business recorded €14,268 in total sales from 487 orders, with a conversion rate of 1.7% over 13,900 sessions. A total of 155 subscriptions have been created, with 70 remaining active. Included in the business package are its domain and Shopify store, brand assets, social media accounts, a customer email list, and 230 units of inventory. The sale also offers the opportunity for a new owner to leverage existing resources such as a supplier contact, which is described as difficult to find. Despite its past success with limited marketing, the current owner is selling the business to focus entirely on a primary brand but is open to assisting with the transition.
