👉 Hapaloderma is a condition that occurs when the skin around the eyes and mouth is covered by a thick, waxy substance known as a haptophyte layer. This layer helps to protect the eye from dust, dirt, and other irritants, while also providing a barrier against bacteria and fungi. Hapaloderma can be caused by various factors such as heredity, environmental exposure, or certain medications. It is often associated with conditions like asthma and allergies.
