# CT Healthcare ## Facts | | | |---|---| | Founded | 2023 | | Origin | Germany | | Headquarters | Berlin | | Status | Active | | Distribution | Multi-channel | | Website | https://ct-healthcare.de/ | CT Healthcare is a German health-products company founded and run by pharmacist Carsten Timmering. Operating as CT Healthcare GmbH under the tagline "Competent Therapeutics", it develops and markets health products for the German market, either as its own formulations or by introducing brands from abroad [1]. Its only consumer product so far is NagelSerum von CT, sold on the company's English-language pages as NagelSerum by CT: a water-soluble nail serum that pairs a chitosan-based film with ciclopirox olamine, sulphur from MSM and silicon from horsetail. The company describes itself as based in Berlin. Its legal notice, however, lists a second address in Seevetal, Lower Saxony, and the commercial register has since recorded Seevetal as the company's address. CT Healthcare is active, with both its corporate site and its product site online as of November 2026. ## Origin & founders CT Healthcare is built around the professional background of its founder. According to the company, Timmering has more than 30 years of experience in pharmacy and the pharmaceutical industry, and it presents him as a specialist in developing and marketing health products and in understanding the needs of the people who use them [1]. He is named as managing director in the company's legal notice, where he appears with the title of pharmacist (Apotheker). The scope of the business is broader than its current single product suggests. The company's registered object, as published in the commercial register, covers the development, manufacture and sale of food supplements, medicines and cosmetics, along with advice to other firms on business development in that field [9]. CT Healthcare GmbH is entered at the Charlottenburg local court in Berlin [3]. ## Philosophy & positioning CT Healthcare frames its purpose around health decisions. Its German homepage opens with the idea that health is not only a matter of chance but also the result of sound choices, and the company says it wants to make those choices easier. Its stated goal is a "marketplace for competent products" that are trustworthy, effective and holistic, backed by open and transparent communication. The company describes its method as combining established ingredients, careful combinations of them and long experience. It says it pairs modern science with traditional healing methods and draws on a global network of partners. In its own words, the aim is to make health innovations with pharmaceutical expertise available in Germany, whether through in-house development or the introduction of international brands that meet high quality and safety standards. That second route is a large part of how CT Healthcare presents itself. A cooperation section on its website invites foreign brands and makers of new ingredients to use the company as a way into the German health market. CT Healthcare says its current focus is on new solutions for skin, hair and nails, where it refines proven formulations and looks for products not yet available in Germany. The English version of the cooperation text names skincare as the present emphasis. ## Products & innovation NagelSerum von CT is an 8 ml serum for fingernails and toenails, marketed on its own website as a "4-fach Formel" (four-part formula). The product site says it is meant to care for thickened and discoloured nails, support the recovery of brittle nails and improve the look of damaged nails. The base of the formula is hydroxypropyl chitosan (HPCH), which the company calls an established film former used in water-soluble nail lacquers. It states that the chitosan is obtained from chitin, the main component of crustacean shells [6]. According to the brand, HPCH forms an invisible protective film that stops the nail losing moisture, and its structure, similar to that of the nail itself, helps it soak into the nail plate. The other ingredients are presented as follows: - **Silicon from horsetail extract** (*Equisetum arvense*): the company says the silica binds with nail keratin, the protein that makes up the nail, and helps rebuild and remineralise its structure. - **MSM (methylsulfonylmethane)**: described as a natural form of sulphur, which the brand calls a basic building block of healthy nails. - **Ciclopirox olamine**: equivalent to 8 % ciclopirox. The company calls it an established ingredient from well-known nail-fungus products, says it is approved for use in cosmetics, and states that it acts as a preservative with an antimicrobial effect against organisms that damage nails [6]. The serum is applied once a day in the evening to clean, dry nails and spread thinly with a brush. It forms an invisible film in under a minute, and no filing of the nail is needed beforehand. Because the base dissolves in water, the residue is washed off the next morning without nail-polish remover. The company recommends a course of up to six months for the fullest result. It also sets the product against conventional nail hardeners, which it says often contain formaldehyde and can leave nails hard but brittle; by contrast, it says the MSM and silicon strengthen the nail while keeping its natural flexibility. The German pharmacy trade journal Pharmazeutische Zeitung carried a short item on the serum in its new-products section. It described the product as a cosmetic whose water-soluble chitosan lacquer technology helps the care ingredients penetrate the nail plate, and listed the same four components [8]. The journal notes that items in that section are compiled from company information, so the piece is a product notice rather than an independent assessment. ### Efficacy claims CT Healthcare says the serum's effectiveness was confirmed in an observational study (Anwendungsbeobachtung) by the University of Naples, with a dermatological evaluation by Dr. Gianmarco Capasso. In the company's account, 30 people aged 22 to 60 used the product once a day for six weeks [7]. The brand reports that 90 % saw a visible improvement, with 30 % of those describing a strong improvement in the overall appearance of their nails. It further reports that 85 % found their nails stronger and more resilient, 80 % noticed less breakage, 80 % reported a smoother, more compact nail surface and 70 % saw a clearer, more even colour with less yellowing. These figures are the company's own statements. Its pages give no publication reference, study design, control group or statistical analysis. The product site is also inconsistent on timing: its main page speaks of improvement after six weeks, while the linked results section is headed "visible improvement after just four weeks". The company states no vegan, cruelty-free or other third-party certifications, and does not say where the serum is made. ## Current status CT Healthcare is active. The serum is sold directly through its product website and through pharmacies, including a number of online pharmacies [4]. The company describes its market as Germany, and no international distribution is documented. The company's location is recorded differently depending on the source. CT Healthcare's own website says it is based in Berlin [2]. Its legal notice gives two addresses, Columbiadamm 33 in Berlin and Kornweg 4 in Seevetal, with the register court in Berlin [3]. The business register aggregator North Data names the company "CT Healthcare GmbH, Seevetal" and lists Kornweg 4 as its address, following a register publication on the address dated 12 November 2025, its most recent entry [9]. This suggests the registered address may have moved to Seevetal while the company continues to describe itself as Berlin-based. As of November 2026, both websites are live and the product site carries a 2026 copyright notice. Neither site links to social media accounts. The company says it is evaluating further product options and invites international brands to work with it, but the nail serum remains its only consumer product. ## Timeline {#belagg-timeline} | Year | Event | Source | |---|---|---| | 2023 | CT Healthcare GmbH entered in the commercial register (Amtsgericht Charlottenburg, HRB 258345 B); managing director Carsten Timmering, share capital EUR 25,000 (North Data, register entry dated 21.11.2023; Tier 4). | https://www.northdata.de/CT+Healthcare+GmbH,+Berlin/Amtsgericht+Charlottenburg+(Berlin)+HRB+258345+B | | 2025 | Register publication 'Anschrift' (address) dated 12.11.2025; North Data now lists the company address as Kornweg 4, D-21218 Seevetal (Tier 4). | https://www.northdata.de/CT+Healthcare+GmbH,+Berlin/Amtsgericht+Charlottenburg+(Berlin)+HRB+258345+B | | — | NagelSerum von CT presented as a new product in Pharmazeutische Zeitung's 'Neue Produkte' section (compiled from company information; publication date not shown on the page). | https://www.pharmazeutische-zeitung.de/zur-regeneration-geschaedigter-naegel-171369/ | ## Signature products {#belagg-products} - **NagelSerum von CT (8 ml, PZN 19902455)** — endlich wieder Nägel, wie Nagelneu. — https://ct-healthcare.de/ ## Key ingredients {#belagg-ingredients} Hydroxypropyl-Chitosan (HPCH) · Ciclopirox-Olamin (equivalent to 8 % ciclopirox) · MSM (methylsulfonylmethane, natural sulphur) · Silicon from horsetail extract (Equisetum arvense) Source: https://www.pharmazeutische-zeitung.de/zur-regeneration-geschaedigter-naegel-171369/ ## Mentioned in {#belagg-press} - **Pharmazeutische Zeitung (German pharmacy trade press)** — Short 'Neue Produkte' item 'Zur Regeneration geschädigter Nägel' on NagelSerum von CT; the section states its items are compiled from company information (not an independent review). — https://www.pharmazeutische-zeitung.de/zur-regeneration-geschaedigter-naegel-171369/ ## Sources 1.
