Lash Brow

Lash Brow is a Polish cosmetics brand from Lublin that specialises in eyebrow and eyelash styling. It was founded in 2013 by Magdalena Barbara Sierocińska and is run as a sole proprietorship registered in Poland's central business registry (CEIDG) [10][6]. The company sells styling soaps, brow pomades, lash serums, mascaras and related tools both to consumers and to beauty salons, and positions itself as a specialist in the brow-and-lash category.

The brand remains active. Its online store publishes a how-to and trend blog on a steady monthly cadence, with posts running through the spring of 2026 [5], and it maintains a following on Instagram under the handle @lashbrow.pl.

Lash Brow began in 2013 as a single-founder venture in Lublin, in the Lubelskie Voivodeship of eastern Poland [10]. It operates under the legal name Lash Brow Magdalena Sierocińska, with Sierocińska listed as the entrepreneur behind the business [6]. Rather than being structured as a limited company, it is a sole proprietorship — a one-person business of the kind common among Polish independent cosmetics ventures. The founding year of 2013 is recorded in the CEIDG public business registry, which for a sole proprietorship is the authoritative source for the start of operations.

The company presents itself as an expert in eyebrow and lash styling, working alongside makeup professionals and stylists while also selling directly to consumers. On its homepage it describes its products as "created with passion for beauty" and says they are meant to help customers highlight their natural beauty "in an easy and safe way." Its Polish-language strapline, "Profesjonalne kosmetyki i akcesoria do stylizacji" — professional cosmetics and styling accessories — frames the brand as a professional-grade option rather than a purely mass-market one.

A recurring theme in how Lash Brow and the retailers carrying it describe the range is the emphasis on gentle, eye-safe formulation. According to one retailer profile, what sets the products apart are their "well-thought-out and natural compositions," built around oils, vitamins and plant extracts [8]. The brand and its stockists also state that the preparations are safe for the eyes and the sensitive skin around them, an assertion they attribute to supporting studies [11].

The brand's best-known product is its brow soap, marketed in Polish as "Mydło do stylizacji brwi" and often referred to as Soap Brow — a solid soap used to set and shape the brows, creating a brushed-up, laminated look with a single product. It is by some margin the most-reviewed Lash Brow item on Wizaz.pl, Poland's main user-review hub for cosmetics, where it carries an average rating of 4.0 out of 5 across 126 reviews [9]. Polish editorial coverage on the same platform describes the soap as the brand's most distinctive product, an eyebrow soap that achieves a lamination effect using just one cosmetic [9].

A second signature item is "Rzęsy w butelce" (Lashes in a Bottle), an eyelash-extending product formulated with microfibres and green tea extract [16]. The product is closely tied to the brand's identity: its official Facebook page is named @rzesywbutelce after it [13]. Related products include "Brwi w butelce" (Brows in a Bottle), the Brows Me Up line of brow pomades, waxes and shadows, and a mascara sold as Mascara HD Pro [8].

Lash Brow runs its own online store at sklep.lashbrow.pl and supplies beauty salons in the lash-and-brow trade, operating across both consumer and professional channels [10]. Beyond its own shop, the range is carried by a number of Polish retailers, including the national pharmacy chain Super-Pharm and the marketplace Allegro, as well as several specialist beauty stores [11]. This spread across drugstore, marketplace and professional-distributor channels reflects the brand's dual audience of working stylists and individual consumers.

The brand is active and operates primarily within Poland. Its store blog posted regularly through early 2026, with the most recent entries dated to May of that year [5], and its shipping options are listed for domestic Polish delivery.
