What Is Myroxylon Pereirae Resin?
Myroxylon Pereirae Resin, often called Balsam Peru, is a naturally sticky oleoresin that oozes from the bark of the Balsam Peru tree, Myroxylon pereirae, a legume native to Central and South America. The raw sap contains a mix of essential oils, cinnamic acid esters and resin acids that give it a rich vanilla-like scent and a tacky texture.
Indigenous communities have tapped this balsam for centuries to scent fabrics, protect skin and add aroma to early personal care balms. European traders brought it to global markets in the 1600s where perfumers prized its warm sweet smell. As modern cosmetics grew, formulators noticed its natural film-forming ability made products feel smoother and last longer.
Harvesters score the tree’s bark, collect the exudate on rags, then boil and strain it to remove debris. The resulting dark brown syrup is cooled into a thick resin that can be blended into creams, sprays and styling aids.
Today you will spot Myroxylon Pereirae Resin in face masks, moisturizers, leave-on hair conditioners, fragrance mists and long-wear makeup where its scent and coating qualities shine.

Comedogenic Rating
Rating: 2 / 5
Myroxylon Pereirae Resin is a thick sticky balsam that can create a breathable film on skin yet it is not rich in fatty acids that commonly clog pores. Most formulas use it at low concentrations for fragrance or hold which limits the chance of buildup. That said its occlusive nature could trap oil and debris if layered in heavy products so those who struggle with frequent breakouts might want to monitor how their skin responds.
Overall it is generally acceptable for acne-prone users but choose lightweight products and avoid combining it with other highly occlusive ingredients if congestion is a concern.
