dsm-firmenich has introduced Glycare SK, a biotechnology-derived skin care ingredient platform based on human milk oligosaccharides (HMOs), positioning the launch within the growing demand for barrier repair and sensitive skin solutions. The company frames the innovation as a response to rising skin reactivity linked to environmental stressors, intensive cosmetic actives and aesthetic procedures, all of which can weaken the skin barrier and increase inflammation, redness and discomfort.
HMOs—complex sugar molecules naturally present in human breast milk—play a critical role in early-life immune development and resilience. Through advances in precision fermentation, dsm-firmenich has replicated these bioidentical structures at scale without the use of human-derived materials. The company states that its production platform represents one of the largest fully integrated HMO biotech capacities globally, enabling consistent, high-purity molecules designed for cosmetic use.
The Glycare SK platform launches with two initial variants: Glycare SK Renew and Glycare SK Comfort. Glycare SK Renew is positioned as a targeted repair ingredient, with in vivo data indicating a 19% reduction in transepidermal water loss (TEWL) after eight weeks compared to placebo, alongside a 38% decrease in visible redness and erythema. The ingredient also demonstrated a 67% increase in collagen I in vitro, suggesting potential benefits for skin structure and recovery.
Glycare SK Comfort, by contrast, is designed for daily use in sensitive skin formulations. Clinical testing showed a 16% reduction in TEWL after eight weeks, as well as a 13% increase in hydration after four weeks. Visible redness was reduced by 3.5% over an eight-week period, supporting claims around improved skin comfort and resilience under routine stress conditions.
Sustainability and sourcing are central to the platform’s positioning. The ingredient is produced using circular lactose feedstock derived from whey, a by-product of cheese manufacturing, with full traceability and production based in the European Union using renewable energy. The company also highlights ongoing efforts to measure and reduce its carbon footprint, including Scope 3 emissions.
