Photosensitivity is a reaction that occurs when some essential oils, when applied to the skin and exposed to sunlight or UV light (such as tanning beds), cause irritation, burns, spots or redness. This reaction is mainly due to the presence of certain chemical compounds, such as furanocoumarins, which increase the skin's sensitivity to light. It is important to take this effect into account when using certain essential oils, especially on areas of the skin exposed to the sun.
Photosensitive Essential Oils
Some of the most common essential oils that can cause photosensitivity are:
- Bergamot essential oil: It is one of the most photosensitive due to its high content of bergapten, a type of furanocoumarin.
- Lemon essential oil: Especially the one extracted by cold pressing, which retains more photosensitive compounds.
- Lime essential oil: Also highly photosensitive, especially when obtained by cold pressing.
- Bitter Orange essential oil: Includes photosensitive compounds in its composition.
- Grapefruit essential oil: May cause photosensitivity when applied to the skin and exposed to the sun.
- Mandarin essential oil: Although it is less photosensitive than the previous ones, it can still cause reactions in sensitive skin.
- Petigrain Bigarade essential oil: Derived from bitter orange, it can be photosensitive although to a lesser degree than other citrus fruits.
Precautions for the Use of Photosensitive Essential Oils
If you want to use these essential oils on your skin, it is important to follow some recommendations:
Avoid sun exposure: After applying photosensitive essential oils to the skin, avoid direct sun exposure for at least 12 to 24 hours (time may vary depending on the specific oil and its concentration).
Use on covered areas: Apply these essential oils to parts of the body that will not be exposed to the sun, or make sure to cover the area with clothing.
Dilute appropriately: Use a low dilution (typically between 0.5% and 2% in carrier oils) to minimize the risk of photosensitivity.
Safe Alternatives: If you need to use a citrus essential oil without the risk of photosensitivity, look for distilled essential oil options instead of cold-pressed ones. For example, some steam-distilled citrus essential oils have fewer photosensitive compounds.
Always consult with an expert: If you have sensitive skin or plan to use essential oils regularly, consider speaking with a dermatologist or aromatherapist to ensure safe use.
When is it safe to use them?
Photosensitive essential oils can be safely used in aromatherapy diffuser blends, in nighttime products, or in homemade preparations that will not be in direct contact with sun-exposed skin. You can also use them in massage oils applied at night or in winter, when sun exposure is limited.
Conclusion
Photosensitive essential oils, such as citrus oils, offer wonderful benefits in aromatherapy and skin care, but it is essential to use them with caution to avoid unwanted reactions. By following these recommendations, you can enjoy its properties without compromising the health of your skin.
