I believe in natural products, but I realize that natural doesn't always mean safe.
What Is Phototoxicity?
Phototoxicity, also known as photosensitivity, photo contact dermatitis, or photo irritation, is an inflammatory skin reaction caused by exposing the skin to an irritant. If you expose your skin to UV light (including tanning beds) after applying certain essential oils, the skin can become irritated. Reactions can appear up to 24 hours after application. This group of essential oils contains furanocoumarins, such as bergapten, which react to UV light. Damage to the skin could be permanent because the skin is exposed to a chemically induced skin irritant.
Symptoms of Phototoxicity on the Skin
- Skin discoloration
- Scaly patches
- Raised skin
Phototoxic Essential Oil Alternatives
It’s not all bad news, though. You can safely use any essential oil if you know how.
For example, a phototoxic essential oil such as cold pressed lemon is not recommended in a face or body cream, but it’s wonderful in diffusers, nasal inhalers, cleaning products or candles.
Another deciding factor is extraction.
For example, cold-pressed lime peel essential oil is phototoxic, but steam distilled lime peel oil is not. Bergamot essential oil is phototoxic, but if it is bergaptene free, then it is not.
The secret to successful essential oil use is to know your oils. It only takes a few minutes to search your ingredients online to ensure that you get the most out of your DIY self-care product.
Use Caution With Citrus Products
The biggest phototoxic culprits are cold-pressed citrus essential oils. However, not all citrus oils cause phototoxicity. Examples of safe citrus essential oils include bergaptene-free bergamot, and steam distilled lemon or mandarin. Please refer to the tabulated list below for more options.
- If you have used any photosensitive oils on your skin, avoid the sun, tanning beds and UV light for at least 12 to 18 hours. This applies to products that remain on the skin, such as creams or serums.
- If you use a product such as a shampoo or a bath product that washes off, you will generally be safer since the product is washed off.
- If you use one of these oils in a steamer for the face or in a sauna, the oil particles will make contact with the skin. Consider taking a shower to remove any residue or stay away from UV light.
What to Consider When Using Phototoxic Oils
- If you apply a product that contains a photosensitive oil, stay away from UV light for a minimum of 12 hours. A facial night cream is a good example here. Keep in mind that some sensitive skin types could still become irritated up to 24 hours after application.
- If you must go out in the sun, make sure that you cover the skin where the potentially photosensitive cream was applied.
- If you experience any irritation, wash it off and stop using the product.
- Always read the ingredients on products before applying them to the skin.
- If the irritation worsens, call your doctor.
- If your skin is irritated, dip a washcloth in whole milk and lay it on the affected area. The high fat and protein concentration in whole milk will soothe the burn and promote healing.
- If you take prescription medication, do some research before using any essential oil products. Some medications, such as tetracycline, may increase your skin’s sensitivity to UV light.
- Always dilute essential oils in a carrier oil, cream, or lotion. This applies to phototoxic and non-phototoxic essential oils.
- Photosensitivity is still a factor in winter because the sun’s ultraviolet rays still reach us.
- If you love lemon or lime in your body cream, consider using steam-distilled versions instead of the cold-pressed citrus essential oils. The table below offers several alternative aroma options.
