RS28 Rejuvenating Serum
With IRISA® Exosome technology: the science to reverse aging
RS-28 Rejuvenation Serum Advanced is the result of 28 years of Swiss cellular research. At its core is the revolutionary IRISA® Exosome technology, internationally patented and 19 times more concentrated than the original formula. These powerful bio-actives are designed to communicate directly with skin cells, reprogramming them at a cellular level to visibly reverse the signs of aging.
This second-generation serum targets visible signs associated with skin aging, such as loss of firmness, uneven tone, and reduced radiance. Its advanced active ingredients, including NAD+ boosters, yeast extract, and Alteromonas ferment, help support the skin's natural renewal process and improve its firmness, elasticity, and smoothness.
Thanks to this unique synergy, RS-28 reactivates the skin's natural 28-day renewal rhythm and accelerates cellular rejuvenation by 90%, for a radiant, firmer, and more even complexion in just 4 weeks.
More than a serum, it is an advanced rejuvenating treatment designed to reveal radiance, elasticity, and visibly revitalized skin in 28 days.Reprogram – Rejuvenate – Revive
