Sun-elastic

• 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.

Anamnesis

• Clinic

• Atrophic epidermis
• Missing subepidermal elastica
• Degenerated, basophilic, bulbous connective tissue fibres which stain like elastic material

Light protection.

Topical retinoids, such as Airol 0.05& lotio or Adapalene gel can be tried.
