What Is Myroxylon Pereirae Resin?
Myroxylon pereirae resin is a natural extract derived from the Myroxylon pereirae tree, native to Central America. It has been used in traditional medicine and cosmetic formulations for centuries, and is commonly known as balsam of Peru in older skincare literature.
In cosmetic products, this ingredient functions primarily as a film former and conditioning agent. It creates a protective layer on the skin or hair surface, which can help improve texture and appearance. The resin also acts as a masking ingredient, contributing fragrance characteristics to formulations.
How It Works
Myroxylon pereirae resin works by forming a thin, occlusive layer across the skin. This film-like coating helps to trap moisture and protect the skin surface from environmental stressors, whilst also creating a smoother tactile feel.
The ingredient's conditioning properties come from its composition of natural resins and volatile oils, which interact with the skin's outer layers to improve hydration and appearance.
Clinical Evidence & References
Research on this ingredient's safety profile is the most established aspect of its use. Studies show that whilst Myroxylon pereirae resin is widely used in cosmetic formulations, it is a known contact allergen. Patch testing studies have identified allergic reactions in a notable proportion of dermatitis patients tested, with rates around 8-9% in some populations.
Evidence for specific skin benefits is limited in published clinical research. Most information about its conditioning and film-forming properties comes from its traditional use and cosmetic industry experience rather than controlled clinical studies. If you have a history of contact sensitivity or fragrance allergies, caution is warranted.
How to Use
This ingredient is typically incorporated into rinse-off products such as cleansers or conditioning treatments rather than leave-on formulations, which may reduce contact time and irritation risk for sensitive individuals. If using products containing this ingredient, introduce them gradually and monitor your skin's response, particularly if you have known fragrance sensitivities.
