Pistacia Lentiscus (Mastic) Gum

What is Pistacia Lentiscus (Mastic) Gum?

Pistacia Lentiscus (Mastic) Gum is the hardened resin obtained from incisions in the bark of the Pistacia lentiscus tree, a small evergreen shrub native to the Mediterranean region, particularly Greece's Chios island. This aromatic, yellowish resin has been harvested traditionally for centuries. In cosmetics, it serves primarily in makeup, nail products, and adhesives due to its tacky, elastic properties. It functions by creating flexible films that enhance product adherence to skin, hair, or nails, resisting water and transfer for extended wear. As a binder, it unites formula components for stable textures in solids like powders. Its mild, balsamic scent acts as a natural fragrance component, contributing to sensory appeal without synthetic notes.
