What Is Pterocarpus Soyauxii Wood Extract?

Pterocarpus Soyauxii Wood Extract is derived from the heartwood of a West African tree species. The extract contains naturally occurring compounds that function as an astringent — a class of ingredient that temporarily contracts or tightens the appearance of skin.

In skincare formulations, this extract is used primarily for its astringent properties, which can help to create a sense of tightness and refined skin texture. It is typically incorporated into products designed to address oily or congested skin concerns.

How It Works

Astringent ingredients work by causing a temporary contraction of the outer layers of skin, which creates a tightening sensation. This effect is thought to occur through the interaction of plant compounds with skin proteins, though the precise mechanism varies depending on the specific ingredient composition.

For Pterocarpus Soyauxii Wood Extract, this tightening action can temporarily minimise the appearance of pore size and create a smoother surface, which is why the ingredient is often found in formulations targeting oily or congested skin.

Clinical Evidence & References

Research specifically on Pterocarpus Soyauxii Wood Extract in skincare is limited, and most evidence of its efficacy remains largely anecdotal or derived from traditional use. The ingredient is recognised by regulatory bodies for its astringent function, but clinical studies specifically measuring its effects on skin appearance or condition are not widely available in the published literature.

What we know about astringent plant extracts more broadly suggests they can produce temporary sensory effects and may support oil control, though results vary based on individual skin and formulation concentration.

How to Use

This ingredient is typically found in toners, astringents, or lightweight serums designed for oily skin. Apply to clean skin using a cotton pad or by patting gently into the skin. It can generally be used once or twice daily, though those with sensitive skin should introduce it gradually to assess tolerance. Layer it under other hydrating or treatment products if needed.

Safety & Precautions

Pterocarpus Soyauxii Wood Extract is generally well-tolerated, though astringent ingredients can occasionally cause dryness or irritation in sensitive individuals. Discontinue use if redness, stinging, or excessive dryness occurs.
