What are light sensitive plasters?

Light sensitive plasters contain a chemical that changes colour when exposed to light. This makes them useful for protecting wounds from infection, as they can be used to block out harmful UV rays. Light sensitive plasters are also often used to treat skin conditions such as eczema and psoriasis, as they can help to reduce inflammation and itching.

The chemical in light sensitive plasters is called methylene blue. Methylene blue is a photosensitizer, which means that it can react with light to produce free radicals. These free radicals can damage bacteria and viruses, making light sensitive plasters effective at preventing and treating infections.

Light sensitive plasters are available in a variety of shapes and sizes, and can be applied to any part of the body. They are typically made from a thin, transparent material that allows the skin to breathe. The plaster will usually change colour within a few minutes of being exposed to light.

How to use light sensitive plasters:

1. Cleanse the wound or affected area with soap and water.

2. Dry the area thoroughly.

3. Apply the light sensitive plaster to the area, making sure that the edges are firmly sealed.

4. Leave the plaster in place for up to 24 hours.

5. Remove the plaster and replace it with a new one if necessary.

Precautions:

* Do not use light sensitive plasters on open wounds or infected areas.

* Do not use light sensitive plasters on people who are sensitive to methylene blue.

* Avoid exposing the light sensitive plaster to direct sunlight or other sources of bright light.

* If you experience any skin irritation or other adverse effects, stop using the light sensitive plaster and consult a doctor.
