Skin light sensitivity, or photosensitivity, is an abnormal or exaggerated skin reaction to sunlight or artificial UV light. This reaction is often triggered by chemical interactions when a substance (a medication or an ingredient in a product) in the skin absorbs UV radiation.

There are two main types:
Yes. While mild reactions may just be painful, photosensitivity is a serious condition because it can be a sign of a severe underlying disease (like lupus) or a life-threatening drug interaction. Severe phototoxic reactions can lead to second-degree burns requiring medical care.
Yes. If the cause is a chronic condition (like lupus) or a necessary medication, a prescription is required to manage the symptoms. Treatment may include prescribed steroid creams, immunosuppressants, or strong antihistamines. Identifying and stopping the trigger substance is the most important step.
Management focuses on strict avoidance and protection. Recommended actions include:
Can common antibiotics cause photosensitivity?
Yes. Certain antibiotics (like tetracyclines) and diuretics are known to cause phototoxic reactions.
Is it the same as a heat rash?
No. A heat rash is caused by blocked sweat glands. Photosensitivity is an inflammatory reaction to UV light on the skin.
Does UV light always cause the reaction?
No. While UV light is the most common trigger, some severe cases can react to visible light, making fluorescent lights or even indoor lighting problematic.
