Some forms of photosensitivity can also increase the risk of skin cancer. Sunlight contains both ordinary visible light and shorter invisible light rays called ultraviolet radiation.
There is enough UVR to cause a rash on photosensitive skin between 10 a.m. and 5 p.m. even on a cloudy day. Bright surfaces, like snow, concrete and sand, reflect UVR and can nearly double the amount that gets to the skin.
- Do not apply perfumes, colognes or aftershave lotions before venturing into the sun as they may cause semi-permanent brown spots on your skin.
- Be wary of medications and the sun as some can make you especially susceptible to sunburn eg. tetracycline, diuretics and some antibiotics.
- Oral contraceptives have been known to cause some women to develop a very unattractive pattern of brown blotches around the eyes from exposure to the sun.
- Certain foods can promote photosensitizing such as citrus fruits and vanilla.
- Restrict outdoor activities to early morning or early evening.
