Why is photosensitivity a concern with St. John's Wort oil, and how should I manage sun exposure?

Because St. John’s Wort is known for causing photosensitivity, this oil is best not applied before sun exposure or UV procedures. Photosensitivity can make the skin more reactive to sunlight, potentially leading to irritation or other adverse reactions. To manage this risk, avoid applying the oil to areas of skin that will be exposed to direct sunlight or strong UV light shortly after use.

For aromatic use, such as adding a drop to a diffuser, this photosensitivity concern does not apply. However, for any topical application, whether for massage, bath mixtures, or cosmetic blends, ensure you are not planning to go into the sun immediately. Always perform a patch test before first use, especially if your skin is very reactive, and start with a small amount to see how your skin responds. External use only; if you have specific skin conditions or concerns, consult a specialist before incorporating this into your routine.
