preval

preval is a German skincare brand made by Preval Dermatica GmbH, a company based in Tangstedt in the Pinneberg district of Schleswig-Holstein, Germany. The company describes itself as a German family business and dates its activity to 1980 [1]. It sells what it calls medical skincare: a compact range of creams, gels, cleansers and treatments aimed at dry, itchy and sensitive skin, at people living with neurodermatitis (atopic eczema) or psoriasis, and at dry hair, an itchy scalp and brittle nails.

The brand is notable less for its size than for its focus. Its range runs to about ten products, most of them built around a single idea: helping a damaged skin barrier recover. The products are sold mainly through pharmacies and through the company's own online shop. In 2025 the brand widened its scope with RE-ACTIN®, a product for thinning hair built on an active complex called Redensyl™ [10]. The company remains active.

Little is publicly known about how preval began. The company's own wording is brief: on its homepage it calls itself "deutsches Familienunternehmen seit 1980", a German family business since 1980, and its research page says it has offered medical care products for skin, hair and nails since that year [3]. No founder is named in the company's public materials, and no founding story is told.

What is documented is the legal shape of the business today. Preval Dermatica GmbH is a German limited company entered in the commercial register at the Pinneberg district court under number HRB 5211, with its registered address in Tangstedt [7]. The company's legal notice names Stephan Conzen and Joachim Jencquel as its representatives. Jencquel also appears on the company's "About us" page as managing director, where his name stands alongside the introduction to the company's vision and values.

The public timeline of preval is short. After the starting point of 1980, the next dated event is recent. In 2025 the company added RE-ACTIN®, a hair-growth product, which received its own page on the brand's website and was presented as new on the homepage.

The launch marked a step beyond the brand's core of barrier-repair skincare. Until then, its hair products had addressed dryness: LIPOJOBA, for instance, is a care shampoo for dry hair and a dry scalp. RE-ACTIN® instead targets hair loss, a different problem with a different kind of active ingredient.

Alongside its products, the company runs an advice section on its website. Under the heading "Wissenswertes" (good to know), it publishes short articles on everyday skin topics, such as keeping the skin barrier healthy while travelling in summer, caring for skin after sunburn and the importance of moisturising regularly. One of these articles cites a study by a German-Swiss team of dermatologists which found that almost one in three people are affected by dry skin.

Preval Dermatica describes itself as a family business, and no parent company, outside investor or acquisition is documented. The company's register entry and legal notice identify it as a German GmbH, with Stephan Conzen and Joachim Jencquel named as its representatives. Neither is described as a founder. Who owns the family business, and how ownership has changed since 1980, is not set out in public sources.

preval positions itself at the medical end of skincare rather than the cosmetic one. The headline on its homepage reads "Medizinische Hautpflege", medical skincare, and the company presents itself as a specialist in that field. Its "About us" page sets the tone with the line that skincare should be more than surface-level cosmetics.

According to the company, its products are developed in close cooperation with dermatologists and contain only what the skin needs to regenerate. It says it deliberately avoids plant ingredients that may trigger allergies [1], presenting them as a possible risk for very sensitive skin rather than a benefit.

The homepage lists the qualities the brand wants to be known for: formulas based on active ingredients, development together with dermatologists, products that go a long way in use, quick and lasting relief, rebuilding of the skin barrier, and good tolerance backed by a dermatological test seal. The company also states that its products are recommended by dermatologists every day.

The brand's stated vision is that people who suffer from skin problems should regain naturally healthy skin, and with it a better sense of well-being and more joy in life [2]. Its tagline puts the same idea in a single sentence: "Mit natürlich gesunder Haut zurück zu Wohlbefinden und neuer Lebensfreude", which translates roughly as "back to well-being and new joy in life with naturally healthy skin". Preval Dermatica names four values that it says guide its work: integrity, closeness and care, experience and research, and efficiency.

The company writes to its readers in a personal, informal register, addressing them with the familiar German "du". Its website also has separate contact points for doctors and for pharmacies, which reflects how closely the brand ties itself to the medical and pharmacy trade.

The range is small and organised by need rather than by product type. The company's all-products page lists ten items: LIPOGEL, LIPOL, LIPOLOTION, LIPOLID, SAPO, ÖLBAD, LIPOJOBA, ONYX, ONYX Pen and RE-ACTIN®. Visitors can also browse by skin condition, from neurodermatitis and psoriasis to allergies, itchy or dry skin, dry hands, dry eyelids, an itchy scalp and brittle nails.

Several products are presented as the brand's main lines. preval LIPOGEL is intended for very dry hands and other very dry areas of skin. preval SAPO is a shower gel for dry skin. preval LIPOJOBA is a care shampoo for dry hair and a dry scalp. preval ONYX is a treatment for brittle or fragile nails, and it also comes in a pen format, ONYX Pen.

Jojoba oil is one of the ingredients the company highlights most. Its ingredients guide describes the oil as particularly helpful for brittle hair and a dry scalp, where it says the oil helps the skin regenerate. The jojoba connection is also visible in the name of the LIPOJOBA shampoo.

RE-ACTIN® is the newest and most heavily promoted product. The company calls it a hair-growth activator and a solution for hair loss. Its key active ingredient, Redensyl™, is a trademarked active complex rather than a technology of preval's own, and the company credits the supporting clinical study to Induchem AG, dated 2014 [10]. According to the company, Redensyl™ has been shown to promote hair growth, with visibly fuller hair after 10 to 12 weeks. The brand's product page goes further, describing the ingredient as twice as effective as minoxidil at promoting hair growth [10]. These figures come from the company's own product page and the study it cites; no independent assessment of the product is documented.

The company publishes a full glossary of the ingredients it uses, each with a short description of its role. It presents this as a matter of transparency. The list includes familiar formulation basics such as water, acetic acid as a pH regulator and preservative, denatured alcohol as a solvent and a gel-forming polymer that leaves a thin film on the skin. It also includes perfume (parfum) and several fragrance components, among them linalool, citronellol and hexyl cinnamal. The company says that because these substances are highly diluted, its products show no intolerance or allergenic potential [6]. The range is therefore not presented as fragrance-free.

Testing and tolerance sit at the centre of how preval describes its products. The company says all of them are tested dermatologically by an independent laboratory [3], and that every product carries the Dermatest seal, a test mark intended to confirm skin tolerance. The seal is shown with the rating "Dermatest geprüft: Sehr gut", meaning "Dermatest tested: very good".

Preval Dermatica also says it chooses its ingredients carefully so that the products are hypoallergenic and suitable for sensitive skin. On its research page, it states that its products are recommended internationally by dermatologists because of their scientifically proven effectiveness. These are the company's own claims; no independent studies of the skincare range itself are publicly documented.

There is one point where the company's own statements disagree. In its FAQ, Preval Dermatica says it deliberately avoids potentially harmful ingredients such as parabens and silicones [8]. Its ingredient glossary, however, lists cyclopentasiloxane, which it describes as a siloxane oil, a type of silicone [6]. Taken together, the brand's own pages support the statement that it avoids parabens, since no paraben appears in the glossary, but not a blanket claim that its range is silicone-free.

No third-party certifications beyond the Dermatest seal are documented. The company states in its FAQ that it does not carry out animal testing [8]; no listing with an independent cruelty-free scheme is known.

Preval Dermatica says it manufactures its products exclusively within Germany, using production processes and packaging that are as environmentally friendly as possible [4]. It adds that its products are made in line with the European Union's cosmetics regulation for skincare products.

The company's social commitments are local. On its "Social engagement" page it names three organisations it supports with donations: Nestwerk, Lebenshilfewerk Pinneberg and the COR-Stiftung foundation.

preval is an active brand. Its website was updated in December 2025, the RE-ACTIN® page was revised in September 2025, and as of October 2026 the company's online shop was operating with products in stock. The brand is sold mainly through pharmacies and through its own shop, which delivers within Germany and to Austria [8]. Its activity is centred on Germany, where the company has its headquarters and production. No social media accounts are linked from the brand's website, and its press page carries no published coverage.
