Givaudan Active Beauty has unveiled PrimalHyal UltraReverse, claimed to be the smallest and most sustainable hyaluronic acid ever developed.
The Swiss company said strain engineering experts at French biotech outfit Alderys has designed an ultra-low molecular weight hyaluronic acid, lower than 3kDa (kilodaltons), which unlocks new biological benefits.
This active ingredient is said to have a unique ability to penetrate skin cells and act at the DNA level, effectively addressing most of the primary hallmarks of ageing.
PrimalHyal UltraReverse targets four of the five primary hallmarks of ageing: epigenetic control; genomic instability; telomeres attrition; and loss of proteostasis.
By targeting these biological pathways, the ingredient protects the skin not only from chronological ageing, but also from environmental stressors known as the exposome.
Givaudan says it increases Sirtuin 1 by +136% and improves Collagen 1 production by +48%, helping to restore skin's youthfulness.
The result is claimed to be visibly younger, healthier skin, with an apparent age reduced by up to six years.
It also corrects key signs of ageing, including wrinkles and sleep lines while offering improved skin firmness, as demonstrated on a diverse and international panel of volunteers.
R&D director Romain Reynaud said: “Produced by precision fermentation, its environmental impact is drastically reduced—setting a new benchmark for sustainable, high-performance skin care."
the ingredient will be debuted at stand 1B120 at in-cosmetics Global in Amsterdam on 8-10 April.
