Myroxylon Balsamum Resin

Myroxylon Balsamum Resin, commonly known as Peru Balsam, is a natural resinous substance derived from the Myroxylon balsamum tree native to Central and South America. It has been used in traditional medicine for centuries, particularly in topical preparations for skin conditions.In skincare formulations, it functions primarily as a film-forming agent and conditioner. The resin creates a protective layer on the skin surface and is commonly included in products designed to soothe and condition, though it appears in a relatively small proportion of skincare products overall.

Peru Balsam works through multiple mechanisms. Its antimicrobial compounds may inhibit bacterial growth on the skin surface, whilst the resinous components form a protective film that reduces transepidermal water loss and conditions the skin. This combination of barrier support and antimicrobial action aligns with its traditional use for compromised skin conditions.The resin also contains compounds that may facilitate skin penetration, allowing other ingredients in a formulation to reach deeper skin layers more effectively.

Peru Balsam is typically used at low concentrations in finished products. As with any botanical ingredient, patch test before introducing it into your routine if you have a history of sensitive skin or known fragrance sensitivities. It is often found in balms and conditioning products rather than daily serums or toners.

Peru Balsam is generally well-tolerated, though contact sensitisation and allergic reactions have been documented in some individuals, particularly those with a history of fragrance or botanical sensitivities. Avoid use if you have known allergy to balsams or related tree resins.
