Excellence Code: A New Chapter in Skin Longevity
Decode the Future
of Skin Longevity
Excellence Code — a new chapter in Yon-Ka's decade-long pursuit of ageing well, guided by the science of longevity and united by Jasmine Absolute.
Since 1954, Yon-Ka's vision has evolved while staying true to its founding values. Today, Excellence Code opens a new chapter.
Inspired by the science of longevity and guided by the belief that true beauty lies in the harmony between skin, wellbeing and time — Excellence Code reflects a decade of Yon-Ka innovation, reimagined. Four exceptional formulas, united by Jasmine Absolute, guided by the science of skin longevity.
Jasmine Absolute, the Botanical Soul of Excellence Code
Delicate, yet remarkably resilient, Jasmine naturally embodies the botanical soul of Excellence Code. A perennial plant that reflowers season after season, its resilience and sensoriality make it the natural incarnation of Yon-Ka's vision of skin longevity.
Jasmine Absolute runs through all four formulas of the range. Nearly 8,000 hand-picked flowers are needed for a single gram — sublimated by the freshness of Neroli and the warmth of Yon-Ka's signature Quintessence, for an unforgettable olfactive signature.
Le Sérum goes one step further. Exclusive to Le Sérum — and to Le Sérum only — a patented Phyto-Fermented Jasmine extract from Grasse, France, selected for its unique ability to stimulate oxytocin — long known for its role in emotional wellbeing, and now recognized as a key player in skin longevity.
Opening a New Frontier in Longevity Science
The study of Blue Zones — regions where people live longer, healthier lives — opened a new era in longevity science. It raised a fundamental question: could the same philosophy apply to skin?
That question guided Yon-Ka Research in creating Excellence Code: four formulas, each designed to address the key biological drivers of skin ageing and to help skin thrive over time — not just look younger, but stay stronger, more resilient and more radiant for longer.
The 360° Approach to Skin Longevity
3 targeted markers of skin longevity
Le Sérum is the most concentrated longevity formula ever developed by Yon-Ka Paris. Its multi-action formula acts on three key markers of skin longevity:

Vitality + Regeneration
+30% SIRT-1¹ — Stimulates longevity genes to boost the energy of tired cells and accelerate skin renewal, with Peach Leaf extract.
Microbiome Balance
+71% hBD3² — Strengthens the skin's microbiological, physical and biological barriers thanks to a pre- and postbiotic complex.
