During the chronological ageing process epidermal skin stem cells become less effective, meaning that the renewing and repairing activity of the epidermis is reduced. Additionally, fewer elastic fibres are synthesised which induces a progressive loss of skin elasticity.
To reduce the signs of chronological ageing Evonik launched TEGO Stemlastin which was also presented at the IFSCC Congress 2012. TEGO® Stemlastin protects and maintains epidermal stem cell capacity and boosts elastic fibre network. This latest active is based on a standardised extract of the micro algae Cyanidium caldarium which is produced in a natural, eco-friendly way.
The algae Cyanidium caldarium is able to survive under extreme environmental conditions. Therefore, the extract delivers a special intracellular composition of extremolytes like mineral nutrients, amino acids, algae polyphenols and is enriched in gamma amino butyric acid (GABA).
Various in vitro studies have shown that TEGO Stemlastin on the one hand protects and maintains epidermal stem cell capacity for rejuvenated skin activity. On the other hand, it boosts elastic fibres leading to highly supple skin and reduction of skin elasticity fatigue. Extended in vivo studies have confirmed that TEGO Stemlastin leads to improved skin elasticity and diminished wrinkle formation, especially manifested in visible reduction of crow's feet.
Through its combined activity on epidermal stem cells and elastic fibres, TEGO Stemlastin clearly retains a youthful appearance and reduces the signs of chronological ageing.
