Purpose
is a natural gum derivative, used in sensitive formulas to tighten and protect the skin. Wrinkle powder/Skin tightening and anti-wrinkle water plays a role in tightening the skin. Acacia is also an economic tree species, and its fragrant flowers can be used to refine aromatic oils as raw materials for high-end perfumes and other cosmetics. The fruit pods, bark and roots contain tannins, which can be used as black dye, and the resin flowing out of the stems contains gum, which is used medicinally. The material is hard and can be used to make valuable utensils.
