Pistacia Lentiscus Gum

Pistacia lentiscus gum, commonly known as mastic gum, is a natural resin extracted from the mastic tree, which grows primarily in the Mediterranean region. It has been used in traditional medicine for centuries and is characterised by its aromatic, waxy composition.In skincare formulations, pistacia lentiscus gum functions primarily as a film-forming agent, creating a thin, protective layer on the skin's surface. It also serves a masking function, helping to improve the sensory appeal of products.

Pistacia lentiscus gum works by depositing a thin film across the skin when applied. This physical barrier can help reduce transepidermal water loss and provide a protective layer against environmental stressors. The gum's natural chemical composition includes compounds with reported antioxidant and anti-inflammatory properties, though the extent to which these benefit topical skin application requires further human studies.

Pistacia lentiscus gum is typically found in small concentrations within formulations (often under 1%), so it functions as a supporting ingredient rather than a standalone active. Use products containing this ingredient as directed on the label. If you have a history of contact sensitivity to botanical resins, fragrances, or adhesive products, apply to a small area first to check tolerance.

Pistacia lentiscus gum is generally well-tolerated in skincare formulations. However, contact dermatitis has been documented in a subset of sensitive individuals, particularly those allergic to related botanical resins or fragrance compounds. Patch testing is recommended if you have known sensitivities.
