Any essential oil should not use under sun?

 

某些精華油含光毒性。它們雖然可以蒸薰法使用,卻不適用於皮膚護理。我們建議客人可混合沐浴露使用,因它們可經水洗淨;但若此類精華油殘留於皮膚並暴露於陽光下,便有機會導致皮膚曬傷或引致雀斑。

以下為含光毒性的精華油:

  • 當歸
  • 佛手柑(除非標明不含香豆素)
  • 茴香
  • 檸檬
  • 青檸
  • 橘子
  • 香橙
  • 馬鞭草
  • 廣藿香

上述精華油並不建議於日光下使用,客人使用前應了解精華油的特性,並遵照指示使用,並可向治療師查詢。

Some essential oils become phototoxic when exposed to direct sunlight. These oils are fine in candles, but shouldn’t be used in any sort of application where the essential oil will stay on your skin and be exposed to the sun. Using these oils in soap is suitable because it will be rinsed off, but using them in a balm or a lotion is not recommended when being expose in the sun for a long period of time i.e going for a sun bath or sun bed because the essential oils stay on your skin.

Below are some of the essential oils that are phototoxic and must be used with caution:

Phototoxic Essential Oils

  • angelica root
  • bergamot (unless it’s specified as “bergaptene-free")
  • cumin
  • ginger
  • lemon
  • lime
  • lovage
  • mandarin
  • orange
  • verbena
  • patchouli

Note: Just because they’re on this list doesn’t mean you can’t use these oils It just means you need to do your research beforehand and know exactly what the characteristics and cautions of that particular oil is. For example, eucalyptus essential oil is generally known to be non-toxic and non-irritating when diluted properly, but it can be very toxic if taken internally. Cinnamon, clove, and many of the “spice" essential oils, can be used safely when are diluted properly and in low concentration but can be irritating if used in too high concentration, or to people with sensitive skin.

Note: This list is not comprehensive of every single essential oil that may cause harm. It is for general information and reference only.
