and skin integrity and optimising skin barrier recovery.
Xilogel and Xilogel HS are two extracts that can be considered as the green alternative to hyaluronic acid. They are obtained from the seed of tamarind tree (Tamarindus indica). They have both shown, in different trials, to enhance skin hydration, improve overall skin elasticity, decrease skin roughness, increase skin density and develop a unique sensoriality, with a special silky and smooth touch.
In & out protection
Some of the Indena extracts can be used also for oral formulations, aiming at ameliorating the skin conditions before and after sun exposure. The effectiveness of these extracts has been clinically tested and they have demonstrated to be effective also from the inside, suggesting a global approach to promoting attractive skin by addressing it both internally and by topical personal care application. Threse are the main examples: the olive extract, the curcuminoids containing extract and the OPC-rich grape seed extract. One more demonstrated stunning properties: Centevita is an extract from Centella
asiatica. The leaves of this plant have been used for centuries in traditional and Asian medicine as an agent favouring the
cicatrisation, thanks to its well-known active components: the triterpenic compounds asiaticoside, madecassoside, asiatic acid and madecassic acid, which are potent promoters of collagen synthesis. This ingredient also contains a fraction of polyphenols, contributing to its observed biological activity. It has been clinically proven as effective in anti-ageing, active in photoageing prevention, and on UV induced DNA protection.
The future: inspired by nature It is well known that sunlight can damage the skin. The most dangerous threat is ultraviolet radiation (UVR), which is a proven human carcinogen. While sunscreen is a well-known and a valuable tool for protecting skin from the sun, dietary supplements can also offer support. Topical creams, yet backed by innovative formulations, may still not be able to guarantee the full protection needed and, at the same time, most people apply sunscreen less frequently, with less attention and less evenly than recommended. Many people believe that to leverage sunscreens during exposure from the sun on vacations and beach days is enough to prevent skin damage, but most sun exposure is incidental to daily living. In fact, it is estimated that for most of our
lifetime sun exposure is incidental, leaving the skin vulnerable to damage for significant portions of time. Adding an edible skin care technology to the daily diet may help to reduce molecular markers of photoageing, inflammation and oxidative stress. These markers and others are directly related to skin ageing, beauty, as well as sunlight related skin diseases. This would be a new, integrated
approach to strengthen our defences against sun damage. Nowadays the approach is necessarily overall healthier and smarter as the reason stays in the middle, i.e. not too much and not too little exposure to the sun. In this sense, plants have been learning how to produce molecules able to counteract oxidation damages, including those generated by sun exposure, over millennia of evolution, and up to now represent one of our most innovative chemical laboratories. Indena has always let itself be inspired by the botanical kingdom, which has translated into high quality standardised extracts for the beneficial plant molecules to become beneficial for human health.
