Essential oil is a skin care product that is applied to the face. It is very friendly to human skin. What will happen when essential oil is exposed to light? How to use expired essential oils?

What happens when essential oils are exposed to light?

When essential oils are exposed to light, the photosensitive components in them will be affected, causing the skin to tan and possibly causing skin diseases.

The reason why essential oils have photosensitivity is because they contain an ingredient called bergamot lactone. Most citrus essential oils contain bergamot lactone, and sandalwood essential oils also contain photosensitivity.

How to use expired essential oils

Essential oils can be used as skin care products, but once they are expired, they cannot be applied to the skin. Essential oils that have expired for a few days can be used in daily household use, as aromatherapy, or to remove odors in the home. Just don't use it on your skin, especially your face.

This is all I have to say about essential oils. Essential oils cannot be exposed to light because they contain photosensitive ingredients. Expired essential oils are not suitable for use on the skin.
