StayLAC

StayLAC is a Polish nail-care brand specialising in hybrid nail polish, marketed as the route to a long-wearing home manicure. It is operated by Cosmo Group Sp. z o.o., a nail-design company based in Kiekrz, near Poznań, and is described by its parent as Cosmo Group's youngest brand [4][5]. The line covers hybrid polishes, base and top coats, a starter set with a UV/LED lamp, and manicure accessories.

The brand remains active. Its site carries a 2024 copyright, and its products are stocked across major Polish drugstore and pharmacy retailers. Within the Cosmo Group portfolio it sits alongside the company's larger nail brand NEONAIL and the make-up line NÉO MAKE UP, and it is the smaller name relative to that flagship.

StayLAC is owned and operated by Cosmo Group Sp. z o.o., a family-run Polish company headquartered in the Poznań area of the Wielkopolskie Voivodeship [4]. The footer of the brand site carries the copyright line "© 2024 Cosmo Group Sp. z o.o." [1], and the company's legal notice identifies Cosmo Group as the operating entity, registered in the Polish National Court Register under KRS 0000437232 [3].

The parent company's own founding date is reported inconsistently. One indexed corporate snippet states that Cosmo Group "was created in Poland in 2006," while another says it has operated "since 2012" [4]; the KRS registration number is consistent with an incorporation of the limited-liability entity around 2012. No source dates the launch of the StayLAC brand itself, which is described only as the group's youngest brand, so its founding year is not established here. Cosmo Group's broader portfolio also includes NEONAIL, NÉO MAKE UP, MYLAQ and NEONAIL Expert [5].

StayLAC's core product is hybrid nail polish, a gel-based lacquer cured under a lamp. The company positions it as a way to achieve a perfect manicure that lasts up to three weeks, "without long waiting times" and "without annoying chips" [1]. The brand's tagline is "Bo liczy się efekt," which translates as "Because the effect matters."

Alongside the polishes, the range includes base and top coats, decorations, and a starter set built around a 10-watt UV/LED lamp [2]. According to the brand's FAQ, correctly applied polish maintains its appearance for roughly 21 days without chipping when the free edge of the nail is sealed, and its remover is based on cosmetic acetone.

StayLAC states that its hybrid lacquers are produced in Europe "according to fair-production principles" [2]. The company also says its hybrid lacquers carry certification, and it directs customers with allergy concerns to check the published ingredient list and perform a patch test before first use [2]. No specific certifying body is named in the available sources.

The brand is sold through multiple Polish retail channels rather than a single store. Its products are listed at the drugstore chain Rossmann, the pharmacy retailer DOZ.pl, and the beauty retailers Hebe and Topdrogeria, among others [2][6]. A separate German-language site, staylac.de, also exists.

StayLAC is active. Its website is current to 2024, and its products remain in stock across major Polish drugstore and pharmacy retailers[1]. It is a minor brand within Cosmo Group relative to the company's flagship NEONAIL line, and on the current version of the parent's brand-overview page StayLAC is no longer highlighted among the featured names [5].
