Lemon balm active ingredient | René Furterer

Extract Lemon Balm

Belonging to the Lamiaceae family and originating around the shores of the Mediterranean, Lemon Balm is cultivated particularly in the temperate climates of North America and Europe. Previously used as an elixir of youth, natural Lemon Balm extract is a powerful antioxidant that slows down collagen depletion.

Hyaluronic Acid Vegetal Like | René Furterer

Hyaluronic Acid Vegetal Like

This exceptional pro-youth key ingredient, 100% natural origin is extracted from Tamarind seeds, a fruit from South-East Asia. Its unique structure gives it the same properties than the hyaluronic acid, an anti-aging iconic key ingredient. It can pump up itself with water to deeply hydrate and fills the space between the scales of the hair fiber to protect hair from dehydration.

Wheat active ingredient | René Furterer

Wheat microproteins

With their strong affinity for the hair, wheat microproteins have the ability to attach themselves to the hair's surface to protect it like a guardian angel. They coat the hair from root to tip, providing bounce and strength. They repair splits in damaged hair.


Derived from soya and exceptionally rich in proteins and fats, Cimentrio is a unique natural complex. It restructures and protects the hair and scalp from external damage.

Essential oil Orange

Imported from the foothills of the Himalayas by Portuguese explorers, sweet Orange was a luxury fruit until the first half of the 20th century.
