EXCEPTIONAL SERUM
LONGEVITY INFUSION

Yon-Ka Paris’ most concentrated longevity formula to date, Le Sérum delivers a 360° approach to skin longevity, uniting breakthrough science with the powerful connection between skin and emotions.With 99.5% ingredients of natural origin, including patented Phyto-Fermented Jasmine technology to visibly improve skin firmness and vitality, and Alpine willowherb to support skin longevity, Le Sérum reveals healthier-looking skin that thrives over time.
More than a high-performance serum, Le Sérum transforms each application into a moment of comfort, confidence, and well-being.

Its light, milky emulsion envelops the skin in a delicate floral fragrance. Jasmine Absolute runs through all four formulas of the range — sublimated by the freshness of Neroli and the warmth of Yon-Ka's signature Quintessence, for an unforgettable olfactive signature.

Result: an immediate plumping effect with a +72% increase in skin hydration in just 1 hour*. Over time, skin appears visibly firmer, smoother, while pores look less visible.

Essential ingredients: Alpine Willowherb, peach leaf extract, pre and postbiotic complex, Jasmine Absolute, essential oil of Neroli, Yon-Ka Quintessence
