What oils should be avoided prior to sun exposure?

Angelica oil should be avoided prior to sun exposure because it is known to be phototoxic. Phototoxic oils can cause skin reactions when exposed to UV light, leading to increased sensitivity, redness, blistering, and pigmentation changes. This reaction is particularly strong when the skin is subsequently exposed to sunlight, making it essential to avoid such oils before sun exposure.

In contrast, while other oils such as frankincense, ginger, and jasmine may have their own specific properties and precautions, they are not classified as phototoxic, making them safer choices to use before sun exposure. Thus, avoiding angelica is crucial for preventing adverse skin reactions when sunlight is a factor.
