Calophyllum Inophyllum (Tamanu) Seed Oil
Tamanu oil is a fascinating natural ingredient that has been scientifically proven to offer multiple benefits for skin health and repair. Extracted from the seeds of Calophyllum inophyllum, this oil contains a unique combination of fatty acids and bioactive compounds that work together to support skin healing and barrier function [1]. What makes tamanu oil particularly special is its resinous fraction, containing compounds like calophyllolide that have demonstrated significant anti-inflammatory and wound-healing properties [2].
For those with dry skin types (Types 1 and 2), tamanu oil can help strengthen the skin barrier and improve moisture retention through its rich fatty acid content. However, those with sensitive dry skin (Type 1) should introduce it gradually and patch test first, as botanical ingredients can sometimes trigger sensitivity [3]. People with balanced skin (Type 3) often find tamanu oil particularly beneficial for general skin maintenance and repair, while those with oily skin types (Types 4 and 5) might want to use it more sparingly or just for spot treatments.
Research has shown impressive results for wound healing and skin repair. Studies demonstrate that tamanu oil promotes collagen production, increases cell renewal, and supports the production of glycosaminoglycans - all crucial factors in maintaining healthy, resilient skin [4]. It also shows promising antibacterial properties, particularly against common skin bacteria, making it potentially beneficial for acne-prone skin when used appropriately [5]. Additionally, its anti-inflammatory properties can help soothe various skin conditions, from general irritation to more specific concerns like rosacea or dermatitis [6].
One of the most compelling aspects of tamanu oil is its ability to support wound healing and reduce scarring. Clinical observations have shown significant improvements in scar appearance with regular use, supported by research showing it enhances wound closure and tissue remodeling [7]. The oil also demonstrates antioxidant properties and some UV-protective effects, though it should not be considered a replacement for proper sun protection [8].
