Heightened skin response to sunlight or ultraviolet light (rapid burning when exposed to the sun).

The characteristic of a material that causes it to change properties when exposed to light.

When essential oils render the skin, in some people, sensitive to sunlight. Always read instructions supplied with an essential oil. Where necessary this possibility will be mentioned.

sensitivity to the action of radiant energy

A reaction or sensitivity to sunlight

an exaggerated sensitivity to light.

An abnormal sensitivity of the skin to sunlight.

Extreme sensitivity to the sun, leaving the patient prone to sunburns. Some cancer drugs and radiation have this side effect.

Extreme sensitivity to the sun, leaving the patient prone to sunburns. This can be a side effect of some cancer drugs and radiation.

Skin condition that makes a person particularly sensitive to ultraviolet radiation. Exposure leads to an allergic reaction such as a rash or severe sunburn. Often associated with the use of certain medications.

Increased sensitivity to the sun’s light or other UV sources.

an increased sensitivity to light, which may lead to easy sunburning and other adverse effects. Photosensitivity is a side effect of some drugs (e.g., dapsone, hypericin).

In medicine, increased sensitivity of the skin to light and other sources of UV. Photosensitivity commonly causes reddening and blistering of the skin with exposure to sunlight and, in time, it heightens the risk of skin cancer. A number of diseases make for photosensitivity, as do scores of prescription and non-prescription drugs. (For details, see Sunburn and Sun-Sensitizing Drugs ). See the entire definition of Photosensitivity

a reflex epilepsy in which seizures are triggered by flashing lights or patterns (e.g., strobe lights, video games, or flipping and rolling of a television screen). An estimated 3 % of people with epilepsy are photosensitive.

Sensitive to light.

Also called photocathode sensitivity. The ability of the photocathode material to produce an electrical response when subjected to light waves (photons). The higher the value, the better the ability to produce a visible image under darker conditions.

causes abnormal reactions to sunlight.

an abnormal sensitivity to light, increasing the chances of severe sunburn; often caused by medication

Allergic reaction to ultraviolet rays (sunlight ea.).

The skin is oversensitive to light.

Hypersensitivity of the skin to sunlight or ultraviolet light (rapid burning when exposed to sun). Some drugs act as photosensitizers and direct exposure bright sunlight may lead to a painful red sunburn-type rash.

A condition in which the sun causes, due to an application or ingestion of certain chemicals or foods, skin problems, such as rash, hyperpigmentation, swelling, and sunburn. Caused by reaction to certain drugs and chemicals as well as Vitamin A (retinol and/or alpha hydroxy acids).

The condition that occurs when skin is sensitized to sunlight, resulting in rashes, blotchiness, swelling, erratic pigmentation changes or other effects. This can occur when certain chemicals are either consumed, or absorbed through the skin on contact.

an abnormally heightened response, especially of the skin, to sunlight or UV radiation, caused by certain disorders or chemicals and characterized by a toxic or allergic reaction

A condition in which the application or ingestion of certain chemicals or foods can cause skin problems, such as rash, hyperpigmentation and swelling, when the skin is exposed to sunlight.

Oversensitivity of the skin to sunlight or other radiant energy, sometimes following exposure to sensitizing chemicals or drugs, resulting in accelerated burning of the skin by ultraviolet (UV) light; possible effects range from itching and swelling to skin cancer. find all NHC pages containing: photosensitivity
