Actinic elastosis, also known as solar elastosis, is an accumulation of abnormal elastin (elastic tissue) in the dermis of the skin, [2] or in the conjunctiva of the eye, [3] which occurs as a result of the cumulative effects of prolonged and excessive sun exposure, a process known as photoaging.
A 3-day treatment course with the 0.015% gel is recommended for the scalp and face, while a 2-day treatment course with the 0.05% gel is recommended for the trunk and extremities. [61] Treatment with the 0.015% gel was found to completely clear 57% of AK, while the 0.05% gel had a 34% clearance rate. [62]

Even without treatment, skin abscesses rarely result in death, as they will naturally break through the skin. [3] Other types of abscess are more dangerous. Brain abscesses may be fatal if untreated. When treated, the mortality rate reduces to 5–10%, but is higher if the abscess ruptures. [38]
