Biosolis

Biosolis is a Belgian suncare brand that makes certified-organic sun protection for the whole family. It launched its first range in 2010 [2] and is based in Thines, in the Nivelles area south of Brussels [1]. The company is known for mineral-filter sunscreens and reef-safe positioning, and it describes itself as one of the pioneers in developing mineral-filter sun protection [2]. As of 2026 it runs an active webshop and sells through several European and international retailers, so the brand is currently operational.

Its stated mission folds environmental concern into the product itself: "Protect us from the Sun... And the Earth from us" [2].

The brand traces its beginnings to a diving trip in 2008, when a co-founder — a lifelong scuba diver — became concerned about coral damage linked to chemical sunscreens [2]. He went on to partner with a collaborator and, working with outside experts, developed a line of natural sun-protection products that reached the market two years later. From the start the proposition tied sun protection to ocean health, a thread that still runs through the company's certifications and partnerships.

Biosolis frames its formulas as "effective, healthy and ecological" and built its early identity around mineral UV filters rather than chemical ones [2]. According to the company, these natural filters work like a mirror that reflects the sun's rays and offer protection immediately, because mineral filters sit on the skin's surface rather than being absorbed. The brand markets itself toward families, children and people with sensitive skin, with formulations aimed at that audience [7].

The original range is described by the company as free of chemical filters, parabens, phenoxyethanol and phthalates, and made with a high share of natural-origin ingredients [2]. Hero ingredients include aloe vera, plant-derived oils, sesame oil and coconut butter.

Biosolis sells sun milks, sprays, dry oils, face creams, after-sun and a self-tanning product, alongside an oral supplement marketed as Suncaps. The catalogue spans common protection levels from SPF 30 to SPF 50+.

The brand's filter chemistry is not uniform across the range, and the sources reflect this. The core and legacy products use 100% natural mineral filters — titanium dioxide and zinc oxide — and retailer and editorial descriptions characterise the brand broadly as "100% natural, mineral protection" [7]. The newer "Sense" line, however, departs from that approach: the company presents Sense as its "latest generation" of sun protection and states that it uses "environmentally-friendly organic filters" described as non-irritating, free from endocrine disruptors and water-resistant [3]. In other words, the claim of being free of chemical filters applies to the original mineral range, while Sense introduces a different, approved filter chemistry; both are stated on the company's own pages.

Sustainability is central to how Biosolis describes itself. The company holds Ecocert Greenlife and COSMOS organic certifications and carries the V-Label from the Vegan Society, which it says certifies the absence of animal-origin ingredients, with the exception of a self-tanning product that contains beeswax [2]. It reports using FSC-certified packaging and tubes largely made from sugar cane, and set a goal to become fully recyclable by 2023 [2].

The brand is a member of 1% for the Planet, committing 1% of gross sales to environmental causes, and it partners with the conservation organisation Reef Check to support ocean and coral-reef protection [2].

Independent coverage of the brand is limited. The ingredient-analysis site What's In My Jar reviewed the Biosolis Sun Milk SPF30 and rated it 90 out of 100 for effectiveness, classifying it as a reef-safe mineral sunscreen built on titanium dioxide and zinc oxide [6]. The same review noted that the filters rarely irritate sensitive skin but can leave a white cast, and that the formula lacks humectants, suggesting it be paired with a hydrating product [6].

Biosolis is active. As of 2026 it operates a live e-commerce shop with a current product range, including the recent Sense generation, and its products are distributed across multiple retailers in Europe and beyond. It remains a modest, niche organic brand rather than a mass-market one, but it is clearly operational.
