K-SECRET

K-SECRET is a South Korean skincare brand based in the Gangnam district of Seoul and owned by KSECRET INC, the legal entity led by chief executive Guyun Jung [1]. It is best known for its SEOUL 1988 line, a range of dermatologically positioned products built around a liposome-delivered form of retinal. The brand site does not state a founding year, but several independent K-beauty editorials place the launch in 2019, describing K-SECRET as "a young Korean brand" started with the founder's motto "Shine today" [14].

The company pitches itself at the meeting point of Korean ingredient heritage and clinical skincare, summed up in its tagline "Inspired by Seoul, Perfected by Derma" [1]. Sold mainly through specialised K-beauty resellers rather than prestige retail, it expanded quickly in the mid-2020s, reporting sales above KRW 18 billion in 2024 [9].

K-SECRET is registered in Korea as KSECRET INC (company number 477-86-01862), with its head office at Samseong-ro in Gangnam-gu, Seoul [2]. The brand site names Guyun Jung as chief executive but, on its English about and brand-story pages, does not give a date of formation [2]. That gap is filled by third-party K-beauty editorials, which consistently report that the brand was founded in 2019 and quote an early guiding motto, "Shine today" [14].

The brand's name is shared with an unrelated company. A separate business at ksecret.com is a multi-brand retailer in the United Arab Emirates and the wider Gulf region that distributes around eighty Korean labels — among them COSRX, Beauty of Joseon and SKIN 1004 — alongside K-SECRET's own products. This article covers the manufacturer KSECRET INC, not that Gulf reseller.

According to the company, K-SECRET sets out to "restore the skin's natural beauty" by combining Korean ingredients drawn from what it calls its heritage with modern, functional skincare science. It frames this around three stated pillars — Heritage, Young Emotion and Transparent — the last defined as developing products that are functionally strong yet still safe. The brand says its aim is to show that gentle, non-irritating ingredients can still deliver visible results.

That positioning leans heavily on dermatological credibility, a theme echoed in editorial coverage that describes the brand as blending traditional beauty wisdom with skincare science to make targeted, gentle formulas [10]. Products are commonly described as dermatologist-tested and hypoallergenic, and free from parabens, sulfates and phthalates; some editorial write-ups also note the absence of alcohol and artificial fragrance [9]. K-SECRET states that all its products are made in Korea [10]. No independent cruelty-free certification, such as Leaping Bunny or PETA, is recorded for the brand; the cruelty-free claim appears in brand and editorial copy rather than as a logged certification.

The brand's flagship is the SEOUL 1988 line, named after the 1988 Seoul Olympic Games — an event the company treats as a symbolic opening of Korea to the world and a reference point for modern K-beauty. The range pairs Korean botanical ingredients such as black ginseng, snail mucin, mugwort, pine cica and fermented rice and bean with the brand's central technical claim: a liposome delivery system applied to retinal. The company and its retail partners describe retinal as a more advanced form of retinol that works "up to 11 times faster," with the liposome system said to improve the ingredient's stability and absorption [9].

Within the line, the SEOUL 1988 Retinal Serum, which combines a 2% retinal liposome with black ginseng, is cited as the brand's hero product and its most popular item on the ingredient database SkinSort [17]. Other products extend the same approach across formats — a higher-strength retinal eye cream with fermented bean, a retinal cream with fermented rice, a snail-mucin essence built on a high concentration of snail secretion filtrate, a pine-cica cleansing oil, and a niacinamide glow serum. Pricing sits in an accessible, indie range, with most items distributed through resellers such as YesStyle, Stylevana, Target and Amazon rather than luxury channels.

K-SECRET's profile rose with the SEOUL 1988 launch. The brand and editorial coverage report that the line was selected as Amazon's Choice soon after release, and a 2024 brand profile cited 2024 sales of more than KRW 18 billion alongside a roughly 70% annual growth rate [9]. The brand was the subject of a YesStyle Brand Spotlight feature in September 2024 [10].

K-SECRET is an active brand. Its site and storefronts remain live, and the SEOUL 1988 catalogue has continued to grow into 2026 with newer additions including a niacinamide serum and capsule cream [21]. Distribution spans Korea's major e-commerce platforms — including Olive Young and Coupang — and a widening set of international markets across North America, the Gulf, India, Japan and parts of Europe.
