Definition:
An increased sensitivity of the skin to UV light. Photosensitized skin will burn, and possibly blister, when exposed to the sun or other UV rays (including tanning beds and booths). Long term, photosensitivity can increase the risk of skin cancer. Photosensitivity can be caused by topical and oral medications, perfumes, or by certain diseases.
Many acne medications increase your sensitivity to the sun, including retinoids (Retin-A, Differin), Accutane (isotretinoin), benzoyl peroxide, and some antibiotics. Talk to your doctor to find out if your medication causes photosensitivity. A broad-spectrum sunscreen must be worn daily to protect the skin from sunburn and sun damage.
