The red maple

The red maple is known for its resistant bark and durability. Through science, Bio ForeXtra reveals the essential synergic active molecules responsible for the protective and resistive properties of this tree. These natural actives are concentrated in the tree’s skin—their bark. They are key factors of tree survival across the seasons, as they are exposed to the extreme environment of Northern Canada.

Borēaline® Expert is the unique extract of red maple bark developed by Bio ForeXtra that allows for the first time to transfer the natural properties of the Northern forest to skin care. Borēaline® Expert is the first fully sustainable and clinically tested cosmetic ingredient obtained from recycled red maple tree bark.

Origin of the red maple

Acer rubrum means “strong” as the robustness of its wood and bark, and “red” for its beautiful flowers and leaves of bright red colours that announce the spring and fall seasons in Quebec. This tree is native to Canada and is one of the major hardwood species of Quebec’s forests. Also known as the Canadian maple, it grows in Canada’s Boreal forest and is the emblem of the Canadian flag.

Traditional usage

Iroquois traditionally crushed dried bark and incorporated the powder in flour for bread preservation. Used in traditional medicine by indigenous peoples (Ojibwa) as an anthelmintic, tonic and treatment for sore eyes. A bark infusion was also recommended to treat cramps and dysentery.
