Kim Sejeong Is REJURAN's New Global Brand Ambassador

Kim Sejeong just became the face of one of Korea's most clinically respected skincare brands. PharmaResearch Co., Ltd. has named the singer and actress as the global brand ambassador for both REJURAN and REJURAN COSMETICS, launching a full-scale international campaign starting March 2026.

The Match Makes Sense

REJURAN built its reputation in dermatology clinics. The brand's injectable PDRN (polydeoxyribonucleotide) skin booster became one of the most sought-after treatments in Korea, attracting a global clientele willing to fly to Seoul for what fans call "salmon DNA" injections. REJURAN COSMETICS extended that clinical heritage into at-home products.

Kim Sejeong's selection is deliberate. PharmaResearch described the pairing as a values match: her image as a grounded, naturally radiant performer aligned with the brand's philosophy of supporting the skin's own regenerative capacity rather than masking it. The brand cited her appeal across generations and her growing international profile as key factors in the decision.

Who Is Kim Sejeong?

Kim Sejeong (김세정) debuted in 2016 through the first season of Produce 101 as a member of I.O.I, then launched her main career with girl group Gugudan. She transitioned into solo music and acting simultaneously, building a rare dual-track career that few K-pop artists manage cleanly.

Her 2022 breakout role in the Netflix and tvN drama A Business Proposal introduced her to international audiences far beyond the K-pop fanbase. The show became a global streaming hit, and her portrayal of the female lead cemented her as a legitimate acting talent rather than a musician taking a side role. Her follow-up drama The Moon Flows on the River, which aired on MBC in 2025, was received with similar enthusiasm.

In early 2026, Sejeong completed an international fan concert tour, 2026 KIM SEJEONG FAN CONCERT, across Seoul, Taipei, and Manila, proving consistent and growing demand outside Korea. That kind of regional footprint is exactly what a brand looking to expand in Southeast Asia needs from its ambassador.

What the Campaign Covers

Starting this month, PharmaResearch plans to roll out a multi-channel global advertising campaign featuring Kim Sejeong across TV, outdoor media, and digital platforms in Korea and internationally. The brand specifically highlighted younger consumers in their 20s and 30s as a target demographic, which tracks with both REJURAN COSMETICS' positioning as an accessible extension of clinic-grade skincare and Sejeong's actual fanbase.

It is worth noting REJURAN has been on a significant expansion run lately. The brand recently signed an exclusive supply agreement with Brazilian aesthetic company DermaDream, and partnered with Laboratoires VIVACY for European distribution. The Kim Sejeong campaign fits into that wider push: a global face for a brand actively building global reach.

A Pattern Worth Noting

This is not Sejeong's first high-profile beauty and lifestyle partnership. She previously served as an ambassador for Longchamp. The REJURAN deal follows a similar logic: premium brands with strong core identities picking a personality whose public image aligns with the product rather than just the audience size.

REJURAN is not a mass-market brand competing on shelf space. It has a specific story about science, skin regeneration, and clinical credibility. Kim Sejeong, known for her authenticity and a public image built on hard work rather than constructed glamour, is a coherent choice for a brand that wants its ambassador to mean something beyond reach and follower counts.
