Industry Briefing: in-cosmetics Korea 2026 Opens July 1 — Plus PFAS Safety Alert, Cosmetology Conference Deadlines, and Summer Sun Protection Trends

This week in cosmetic science: Seoul prepares to host Asia’s premier personal care ingredients expo, new research raises fresh concerns about PFAS in makeup, Bangkok’s cosmetology conference enters final early-bird registration window, and summer 2026 heatwaves push sun protection science into the spotlight.

1. in-cosmetics Korea 2026: Personal Care Ingredients Expo Returns to Seoul (July 1–3)

The only exhibition in Korea dedicated exclusively to personal care ingredients opens its doors at COEX, Seoul, from July 1 to 3, 2026. With over 800 exhibitors across 30,000 m² and an expected 50,000+ attendees, the event serves as the primary sourcing and networking hub for Asia-Pacific formulators, brand owners, and ingredient innovators.

This year’s show focuses on biofermentation-derived actives, microbiome-friendly preservative systems, and next-generation delivery technologies — reflecting the region’s push toward “clean” yet high-efficacy formulations. Official supporter KCA (Korea Cosmetics Association) continues its partnership, reinforcing the event’s regulatory credibility.

2. New Study Links Cosmetic PFAS to Immune, Metabolic, and Reproductive Harm

Researchers from the University of São Paulo published findings in Archives of Toxicology showing that per- and polyfluoroalkyl substances (PFAS) commonly found in cosmetics — particularly lip and eye products — can trigger immunotoxicity, disrupt metabolic function, and impair reproductive development. The study highlights that PFAS in personal care products exhibit strong environmental persistence and bioaccumulation, compounding long-term exposure risk.

This adds urgency to ongoing regulatory conversations in both the EU (under the proposed universal PFAS restriction) and the US (state-level bans in California, Colorado, and Maine). For formulators, the implications are clear: fluorinated ingredient alternatives — including silicone-based film formers and bio-based waxes — are becoming a competitive differentiator.

3. Cosmetology Aging Conference 2026: Early Bird Registration Closes June 30

The 2nd Edition of the Cosmetology Aging and Rejuvenation World Conference (CARWC 2026) will be held October 18–20 at the Ambassador Hotel Bangkok, Thailand, with a hybrid virtual attendance option. Early bird registration ends June 30, 2026 — just two days from now.

The scientific program covers skin aging biomarkers, senolytic ingredients, peptide-based rejuvenation strategies, and post-procedure cosmeceutical regimens. The conference is organized by Precision Global Conferences and expects 100+ visitors from both clinical dermatology and cosmetic formulation backgrounds.

4. Summer 2026 Sun Protection: UV Levels Hit Extreme Across East Asia

As of late June 2026, daytime UV indices across North, East, and Central China have stabilized at Level 5 (very high to extreme), driving a surge in consumer demand for broad-spectrum sun protection. Social media trends show “scientific sun protection” overtaking “whitening” as the dominant skincare narrative this season.

Key formulation angles gaining attention include: visible-light (HEV/blue light) protection beyond UVB/UVA, antioxidant-boosted sunscreen actives (e.g., licochalcone A, ferulic acid combinations), and water-resistant mineral formulations optimized for sensitive and post-procedure skin. The convergence of extreme weather and educated consumers is reshaping the sun care category from seasonal afterthought to year-round core routine.

5. in-cosmetics Latin America 2026 Set for September in São Paulo

in-cosmetics Latin America returns September 23–24, 2026, at São Paulo, Brazil. As the leading personal care ingredients event for the LATAM market, this year’s edition places emphasis on Amazonian biodiversity-derived actives, sustainable sourcing certification, and the region’s rapidly evolving regulatory framework under ANVISA and Mercosur harmonization.

For Asian ingredient suppliers and brands eyeing Latin American expansion, this event provides a strategic entry point — particularly as Brazil’s cosmetics market continues to grow at a projected CAGR of 4.5% through 2028, driven by premiumization and dermatologist-recommended skincare categories.
