L23.4: Allergic contact dermatitis due to dyes

Your skin has come into contact with dyes. Your skin has become inflamed as result.

Your skin has come into contact with dyes. These substances irritate your skin. When your skin has repeated contact with them, it overreacts to substances that are actually harmless. If the skin is irritated by these substances for a long time, it becomes inflamed. The surface of the skin gets damaged as a result.

Symptoms can vary in severity. It depends on how long and how close the skin contact was. Initially, the skin is usually red and swollen. Blisters or weeping open wounds occur. Then yellowish crusts often form. If the allergenic substances are constantly damaging the skin, the skin can thicken and crack. The skin may also be flaky. Because the skin can be very itchy, you often have to scratch yourself.

Initially, the skin changes at the point of contact with the allergenic substances. However, when there is longer contact, the skin changes can spread to other areas of the skin.

If the skin has no contact with the allergenic substances for a long time, the skin is able to recover. If the skin comes into contact with the allergenic substances again, the skin changes usually recur after one to two days. After the allergenic substances have been discarded, the skin changes only fade away slowly.
