The discovery of the natural antiwrinkle hibiscus extract

American researchers have discovered an active ingredient which, when applied to the skin, develops an effective anti-aging activity:Hibiscus Extract (INCI list: Hydrolized Hibiscus Esculentus Extract) It has been demonstrated with an in vitro test that, thanks to its high concentration of "biomimetic" natural oligopeptides, the extract inhibits muscle contraction, with the cosmetic effect reflected in the skin of "reduction of expression lines". This was demonstrated* with an innovative test, carried out on cell cultures that simulate the hypermobility of facial muscle, where it was found that Hibiscus esculentus contains a muscle-relaxing mechanism which inhibits the frequency of contractions, mimicking the action of botulinum toxin and with an effect lasting for hours.

The Oligopeptides of the Hibiscus are small protein fractions constituted by 3-4-6 amino acids in a predetermined sequence, which reproduce sequences of important proteins similar to those of the dermis's support structures, collagen and elastin, reinforcing them and counteracting their degradation due to age and to environmental aggressions.

The researchers also demonstrated that Hibiscus effects a marked antioxidant activity, inhibiting the formation of free radicals and so increasing the skin's defenses against exogenous and endogenous aggressions.

Results: facial features and wrinkles appear more relaxed, skin texture is firmer and more homogeneous with a cosmetic effect of overall rejuvenation.
