- Solar elastosis
- Elastosis solaris
- Elastosis senilis
- Senile elastosis
- Actinic elastosis
- Degeneration of the collagen fibres with consequently increased wrinkle formation and irregular pigmentation.
- occurs exclusively in lighter skin types.
- Older people.
- UVA/ UVB/IR radiation all seem to have a causative effect. There is a release of oxygen radicals (singlet oxygen, superoxide anion/ hydroxyl radical) and indirectly increased synthesis of metalloproteinases, which lead to destruction of structural proteins, disturbances of connective tissue metabolism and destruction of existing collagen.
- Wrinkling (age wrinkles) and pigmentation (lentigo solaris) occur in the area of UV-exposed areas.
- Atrophic epidermis
- Missing subepidermal elastica
- Degenerated, basophilic, bulbous connective tissue fibres which stain like elastic material
