Appeal of marine naturalness is coupled with strong expectations for efficacy
As the cosmetic market enters the "Science-Based Beauty" era, the appeal of marine naturalness is coupled with strong expectations for efficacy: brands demand total transparency and tangible biological proof.
To address the first trend, which involves seeking healthy and balanced skin, Phlorogine™ CV, an extract of Laminaria Saccharina, has its purifying efficacy confirmed by new in vivo data validating a triple action: sebum level is reduced by 29.3%, visible imperfections decrease by 10.8%, and complexion radiance is revived by +20.3%.
Targeting deep longevity mechanisms to meet "Well-aging" expectations, Aspar'Age™ (Asparagopsis Armata) confirms its in vivo action against "contagious aging" by protecting young fibroblasts from the SMS (Senescence Messaging Secretome) emitted by senescent fibroblasts. At 2%, the active ingredient reduces the length of crow's feet wrinkles by nearly twice as much as the placebo. Efficacy is visible: the skin appears significantly younger, less tired (77%), and more uniform (68%).
Finally, to meet the growing demand for gentle alternatives to hyaluronic acid injections, the biotechnology-derived ingredient Celtosome™ Eryngium Maritimum confirms its role as a biotech "filler." While in vitro tests already demonstrate an increase in Hyaluronic Acid production of +103% and a strengthening of Collagen I (+28%) and Elastin (+34%), the clinical study reveals a real smoothing effect. After 28 days, wrinkle surface area is reduced by 12%. The active also offers immediate hydration superior to the placebo. Acclaimed by consumers, it leaves skin smoother to the touch for 71% of volunteers and provides an improved general appearance for 74% of them.
