Sunlight contains ultraviolet A (UVA) and ultraviolet B (UVB) radiation, both of which can be harmful to the skin, as reported by the NHS.

Light is often referred to as a spectrum consisting of ultraviolet light (UV) which can’t be seen, and infrared light which can be felt as heat.

Most damage to the skin from sunlight is due to ultraviolet light because it can penetrate the skin surface. This damage occurs in everyone, including those who are allergic to sunlight.

Lustalux has been protecting people suffering from ultraviolet related skin allergies for almost 25 years now...

What are sun allergies?

Sun allergies are very common, especially among young women and people with fair skin.

Also known as photodermatitis, it is an immune system reaction to sunlight, most often in the form of an itchy red rash. The most common form of sun allergy is Polymorphous Light Eruption (often abbreviated to PLE).

However, there are rarer forms of allergies, and one in particular that we’ve been associated with for almost 25 years now. Xeroderma Pigmentosum (XP).

What is Xeroderma Pigmentosum (XP)?

Xeroderma Pigmentosum or XP as it is more commonly known, is an extremely rare, genetic allergic condition where sufferers react to sunlight causing blistering to the skin.

It is an inherited condition characterised by extreme sensitivity to UV rays, and it mostly affects the eyes and areas of skin exposed to the sun. Some individuals also develop problems with their nervous system.

There is no cure and it affects less than 100 people in the UK.

The difference between those who have XP and those who don’t, is that the damage caused by UV light manifests itself more rapidly and will never be repaired. This inevitably leads to skin cancer.

Our story with XP goes back to 1995...

We were approached by a family from Skelmersdale, Lancashire who had two children suffering from Xeroderma Pigmentosum.

Lustalux installed Derma-Gard UV Window Film to the family’s home, car and to the windows of the children’s school. The film application meant that the family no longer had to keep their house curtains drawn and the children were able to travel and attend school without fear of an allergic reaction.

The full story from 1995 can be seen in the original news article below:


Since 1995, we have been able to assist people of all ages by installing DermaGard to windows at home, school and work. We’ve even had cases where we have helped children through nursery, primary school, high school and further education; giving them daily UV protection.

What is Derma-Gard?

Derma-Gard is an optically clear, technically advanced film which, when professionally installed, is virtually undetectable on the glass.

It is specially designed to filter out Ultraviolet (UV) radiation, and there is no loss of natural daylight with clear vision through the glass which makes it perfect for car and building windows.

What’s more, it’s scratch resistant coating makes it easy to clean and needs zero maintenance.

Therefore the application of Derma-Gard protects everyone from the damage that UV can do; including making life more normal for those that suffer from light sensitive conditions, such as XP as well as Systemic Lupus Erythematosus (SLE or lupus).

Lustalux has the solution

All Lustalux window films have UV screening properties reducing UV transmission down to 1% at 380nm.

However, Derma-Gard reduces the UV transmissions down to a maximum of 0.5%, up to 380nm and 1% in the range between 300nm and 400nm.

It gives us immense pride knowing for the last 25 years we’ve been helping those with skin allergies by giving them a little more freedom, so they don’t have to live behind closed curtains or venture outdoors at night-time.
