Atrophy of the skin in older people due to endogenous (intrinsic) and external (extrinsic) influences.

This section has been translated automatically.

Basically, the aging process of the skin can be divided into:

  • intrinsic aging, the natural, physiological aging process, which begins after the 4th year as simple atrophy of all skin layers and is mainly influenced by genetic factors.
  • extrinsic aging (UV damage to the skin/photoaging, smoking, alcohol, stress, other environmental toxins).

The extrinsic aging process will be observed exclusively on the skin areas that are preferably exposed to sunlight (face; neck, nape of neck, décolleté, forearms, back of hands, lower legs).

Clinical features

Yellowish or grayish-yellowish, but also piebald hyperpigmented due to chronic actinic influences, flabby, usually dry, withered, parchment-like skin, often interspersed with telangiectasias (especially on the face and thorax) and with marked prominence of the larger venous and arterial vessels lying under the skin (as in an anatomical specimen), with increased wrinkling and puckering. Subdivision of the skin into coarse rhombic fields. Often leucomelanodermic pigmentary shifts, decreased sebaceous and sweat gland activity with marked exsiccosis of the skin. Hair and nails change structurally as well as in their growth. Subcutaneous adipose tissue changes structurally, resulting in irregularities in the surface appearance of the skin/adipose tissue compartment.

The following changes are observed during senile involution of the skin, skin appendages, and subcutis:

Chemical peeling: For fine lines, e.g. peeling with alpha-hydroxy acids (glycolic acid), for deeper wrinkles, especially perioral and periorbital, e.g. peeling with trichloroacetic acid.
