Learn more about Sodium HyaluronateCitrus Aurantium Bergamia Fruit Oil is the oil from the bergamot orange. It is native to Italy.
This ingredient is used to add fragrance to products. It contains limonene, linalool, and linalyl acetate.
The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.
When used topically, Citrus Aurantium Bergamia Fruit Oil is a photosensitizer due to its furanocoumarins. Photosensitizers make the skin and eyes much more sensitive to sunlight. Photosensitizers are linked to skin cancer.
However, more cosmetics using Citrus Aurantium Bergamia Fruit Oil are removing the furanocoumarins.
Bergamot oil was also found to have anti-inflammatory, antibacterial and antifungal properties.

I’m not sure why this product irritates my skin! It causes hives. Burns a little as well. Maybe it’s the citric acid? I have super sensitive skin and my skin won’t tolerate this product.
