The extract of Lolium perenne L. (ryegrass) flower is a new anti-aging active ingredient containing vitamins, oligo-elements and amino-acids, a complex of active principles essentials for the energy processes taking place in living cells. As the natural building blocks of cells life, the components of this extract support the energy machinery of skin cells and protect the skin structure against the aggression of environmental pollution, oxidative agents and chronic inflammatory factors.
The results of in-vitro and in-vivo tests demonstrate many skin benefits (implementation of protective components) leading to a reduction of visible marks linked to progressive skin aging.
The solvent-free, non-allergenic extract of ryegrass flower is carefully obtained from standardized raw materials. Moreover, it is non-preserved, completely water-soluble, has a light flower scent and exhibits good compatibility with most cosmetic ingredients.

While the sequence of the ageing process is noticeable in all body organs, it manifests very visibly in the skin. As skin is the communication link between individuals, maintaining a young appearance and healthy skin while preventing the evident damages of aging are key requirements for a good relationship with ourselves and the others.
All skin structures, functions and appearance are impaired by age. The oxidative stress is considered of primary importance in driving the ageing process. Substantial evidence exists to support that ageing is associated with the consequences of free radical damage induced by various reactive oxygen species (ROS). ROS include the superoxide, the hydroxyl radicals and other activated forms of oxygen, such as hydrogen peroxide and singlet oxygen. Ageing is associated with changes in the molecular structure of DNA, proteins, lipids, and prostaglandins – all markers of oxidat ...
