OnlyBio

OnlyBio is a Polish natural cosmetics brand based in Bydgoszcz, producing vegan face, body and hair care for women, men and children. Its products are made by Laboratorium Naturella, the company that now operates as Onlybio.life S.A. [5] The brand builds its formulas around biorefined surfactin, a plant-derived surfactant obtained from Polish rapeseed, and positions itself as an eco-conscious label whose stated aim is to change everyday cosmetic habits.

According to the company, OnlyBio was born "from a desire to change the world to be more eco, by changing the cosmetic habits of each of us." [4] The brand remains active: it runs an operational online store, sells through the Rossmann and Hebe drugstore chains, and ships to more than two dozen European Union countries.

OnlyBio developed as the cosmetics line of Laboratorium Naturella, a Polish producer that also makes natural cleaning and laundry products under the OnlyEco name. [5] Editorial coverage credits the OnlyBio formulas to Tomasz Wasilewski, an associate professor of cosmetology, while the OnlyEco range is attributed to Jadwiga Wysocka. [5] The brand's own pages do not name individual founders.

The founding year is not documented on OnlyBio's own site, and business registries give two different dates. A directory listing records 2012 as the year the company began operating on the market [7], while the Polish National Court Register shows Laboratorium Naturella Sp. z o.o. as registered on 23 July 2013. [8] Both figures come from registry aggregators rather than the brand itself.

The producer behind OnlyBio is Laboratorium Naturella Sp. z o.o., which now trades as Onlybio.life S.A. and is registered in Bydgoszcz. [5][6] The same company operates both the OnlyBio cosmetics line and the OnlyEco household range, framed as a shared portfolio of natural products for adults, children and the home. [5]

OnlyBio presents itself as a natural, vegan brand and states that its products contain at least 99% ingredients of natural origin. [3] The company describes its purpose in ecological terms, and the values highlighted on its site include responsibility, ecological living, family, quality, education and animal-friendliness. Products are positioned in the drugstore price tier and distributed both online and through mainstream retail.

The hero ingredient across the range is biorefined surfactin, which the brand sources from Polish rapeseed. [5] Marketing materials also reference a second proprietary biosurfactant, levan, with both described as offering moisturising and anti-ageing properties. [4]

The brand's catalogue spans hair care, body care and facial skincare, with a dedicated children's line. Hair care is the largest segment, organised into series such as Hair Cycling and Hair in Balance, the latter split into variants for volume, gloss, repair, hydration and colour-treated hair. OnlyBio also markets a range of flavour-inspired hair toners, with names such as "Dark Chocolate" and "Marshmallow Blonde," and an "Imperfect But Excellent" line of products sold at reduced prices because of packaging flaws.

Beyond physical products, the company operates a loyalty scheme called OnlyBio Club and a mobile application, OnlyBio Stories, which it says has passed 100,000 downloads and offers personalised hair-care plans. Product collaborations have included tie-ins with the Polish confectioner E. Wedel and the juice brand Tymbark.

OnlyBio's products carry several certifications. According to the company and Polish editorial coverage, the range holds Vegan Society certification and EcoCert COSMOS certification in the Natural standard [5], and the brand's about page also displays an asthma and allergy approval mark and states that its products are recommended by the Polish Dermatological Society. The company additionally cites the use of recycled plastic and eco glass in its packaging. [4]

OnlyBio is active. As of 2026 it maintains a functioning e-commerce site with current product lines, an operating loyalty programme and mobile app, retail distribution through Rossmann and Hebe, and shipping across the European Union.
