Citrus Aurantium Bergamia Leaf Extract

Citrus Aurantium Bergamia Leaf Extract is derived from the leaves of the bergamot orange tree, a citrus plant native to southern Italy. The extract is obtained through processing the leaf material to isolate its active compounds, which include flavonoids and volatile oils.In skincare formulations, this ingredient is primarily used for its astringent function — meaning it has a tightening or pore-refining effect on the skin. Astringents work by causing a temporary contraction of skin tissue, which can create a perception of smoother, more refined skin texture.

Astringent ingredients work by temporarily contracting skin tissue through protein binding and mild dehydration of the upper skin layers. In the case of bergamia leaf extract, the flavonoids and other phytocompounds in the extract interact with skin proteins, creating this tightening sensation.This effect is temporary and does not permanently alter pore size or skin structure. The antioxidants present in the extract may also offer some protective benefits against oxidative stress from environmental factors.

This ingredient is typically found in very low concentrations in skincare products (around 0.1% or less in most formulations). It is usually included as part of a toner, essence, or treatment product rather than as a standalone ingredient. Use as directed by the product instructions — usually once or twice daily after cleansing. If you have sensitive skin, patch test first, as citrus extracts can occasionally cause irritation in susceptible individuals.

Generally well-tolerated in skincare formulations. Citrus extracts can occasionally trigger sensitivity or photosensitivity in some individuals, particularly at higher concentrations, so sun protection is advisable if using citrus-rich products.
