The eyelid skin is the thinnest and most sensitive skin on your body. As a result, this is often the first area on your face to show change from sun damage and aging. Unfortunately, sun damage and other environmental toxins not only cause the skin to age but can cause serious damage. Skin cancer of the eyelids is relatively common and several types exist. The presence of a nodule or lesion on the eyelid that grows, bleed or ulcerates should be evaluated. This involves examination and sometimes a biopsy.
