Photosensitivity: What It Is and How to Use Citrus Oils Safely
Understanding Photosensitivity
Certain essential oils can increase the skin’s sensitivity to sunlight. This reaction, known as photosensitivity, occurs when compounds interact with UV exposure.
Common Photosensitive Oils
- Bergamot (non-FCF)
- Lemon
- Lime
- Grapefruit
These oils contain compounds that can trigger reactions when exposed to sunlight.
Safe Use Guidelines
- Use diluted formulations
- Avoid sun exposure after application
- Choose FCF (furanocoumarin-free) options when available
A Balanced Approach
Citrus oils are valuable—bright, uplifting, and effective. Safe use allows their benefits without unnecessary risk.
