Cosnori

Cosnori is a South Korean beauty brand based in Seoul, best known for eyelash serums and tone-up base products. It is the flagship line of Graceclub Corporation, a Korean company that manufactures, imports and distributes beauty and diet-food brands. The company dates the Cosnori brand to a 2012 launch [3], distinguishing it from its parent firm, which was founded in 2001 [3]. The brand remains active and sells in roughly 60 countries.

Positioned as a "total beauty" line, Cosnori centres its range on plant-derived ingredients and what it describes as honest, healthy formulas. Its eyelash serum has become the brand's commercial anchor, with the company reporting strong sales in Japan and an expansion into U.S. retail in 2025 [3].

Cosnori belongs to Graceclub Corporation, registered as GRACECLUB CO., LTD. and headquartered in the Guro district of Seoul. The company was founded in 2001 by Jun-Tak Chang, who is listed as its founder and chief executive [3]. According to its company page, Graceclub specialises in manufacturing, importing and distributing beauty and diet-food brands.

The Cosnori brand itself was launched in 2012 as Graceclub's "total beauty" line. This two-stage history is the source of a recurring discrepancy: the official company page records 2001 as the founding of Graceclub and 2012 as the launch of Cosnori, while some third-party listings conflate the two and describe the brand as established in 2001 [6]. Cosnori sits within a wider portfolio that also includes Green Monster, a health-food brand launched in 2016, and 8grow, a hair-care line launched in 2019.

The brand's range spans skincare and makeup, with a particular focus on eyelash care and complexion bases. Its signature product is the Long Active Eyelash Serum, which the company says is clinically proven to improve lash length, thickness and vitality within weeks. A companion Eyelash Tinting Serum incorporates plant-derived colourants the brand describes as drawn from "four types of black foods." On the complexion side, Cosnori markets the Whitening Dress Tone-Up Cream, which it calls the "first tone-up cream of the kind" and describes as dermatologically tested, alongside the Your Skin Dress Tone-Up Base with built-in UV protection. The Panthenol Barrier Toner ranks among its highest-reviewed items on the Korean review platform Hwahae [6].

Cosnori attributes its formulas to what it terms exclusive peptide patent ingredients, high-concentration panthenol and a naturally derived component it calls Serabyne [6]. Documented active ingredients in its eyelash products include the peptides Myristoyl Pentapeptide-17, Copper Tripeptide-1 and Copper Tetrapeptide-52 Dimer, together with sodium hyaluronate, centella asiatica extract and panthenol. The brand's marketplace listings also describe the eyelash serum as prostaglandin-free, a point of differentiation in a category where prostaglandin analogues are common.

Cosnori presents itself as a "total beauty" brand built on honest, healthy and naturally derived ingredients, under the tagline "Your beauty turning point." The company frames its mission as discovering new ingredients suited to current beauty trends and bringing what it calls honest and healthy products to market. Its stated core values include using naturally derived ingredients with a differentiated recipe, retaining the properties of raw materials, and adhering to hygiene standards.

According to Hwahae, the brand targets consumers who prioritise skin health and prefer well-chosen ingredients, including those new to beauty routines, with sensitive skin cited as its primary target skin type [6]. The same profile associates Cosnori with the K-beauty, clean-beauty and vegan-beauty movements.

Cosnori emphasises scientific and eco-friendly, naturally derived ingredients while, in its own words, retaining the properties of the raw materials. On animal welfare, roughly 30 percent of the brand's products carry vegan certification according to Hwahae [6], and editorial reviews report that its eyelash products are described as certified vegan, free of animal-derived ingredients and not tested on animals [8]. Manufacturing is based in South Korea.

On Hwahae, South Korea's leading independent cosmetics review and ingredient-analysis platform, Cosnori lists around 230 products with an average rating of 4.43 across more than 34,700 reviews, and is tagged with keywords such as "category leader," "honest ingredients" and "vegan-oriented" [6]. The Long Active Eyelash Serum is among the platform's most-reviewed items.

The eyelash serum is also the focus of most external coverage. K-beauty editorial outlets report that it has been recognised by Hwahae, Olive Young and Glow Pick, prominent Korean beauty award and ranking platforms [8], with one review describing it as winner of the Olive Young Awards for three consecutive years and as "Korea's No.1 Eyelash Serum" [9]. The company's own marketing goes further, calling it the "Cosnori No.1 Eyelash Serum" and a 21-time beauty award winner [1]; these self-stated figures are not independently itemised in the available sources.

Cosnori is an active, multi-region brand. Its parent company reports that in 2025 it launched Cosnori in Costco's U.S. online and physical stores and that more than one million units of its eyelash serum had been sold in Japan [3]. Combined with distribution across roughly 60 countries and a large review presence on Korean platforms, the brand is clearly operating rather than dormant.
