Skin wrinkles are the furrows and wrinkles existing in the skin due to increasing mechanical stress at this point and due to the natural aging process.
Development of wrinkles
In order to treat wrinkles, or to prevent them from developing in the first place, knowledge of their origin is necessary. Wrinkles are natural and belong in the skin of people of all ages. The moment facial expressions or gestures change, the skin must adapt elastically to the facial movements.
In doing so, it automatically creates wrinkles. This happens regardless of age. However, this process is reversible, i.e. once the mimic process is complete, the wrinkles usually disappear again.
The formation of wrinkles is therefore initially a mechanical process. Prerequisites for “wrinkle throwing” and again “unfolding” are elastic fibers of the skin, which are mainly interspersed with numerous amino acids. The skin is the largest organ of the human body, which spans it completely.
Under the skin there are numerous muscles. In the face, it is mainly the mimic muscles that contribute to the formation of wrinkles. Every change in facial expression is accompanied by a contraction of the mimic facial musculature.
This process shifts the overlying skin and thus causes wrinkles to form. Once the mimic muscles have relaxed, the skin usually adapts to the new situation without wrinkles and is smoothed. Strong and frequently stressed regions of the face show a slight permanent furrow of the skin quite early.
This can usually be seen around the eyes, regardless of age, and the skin often has to adapt to new facial expressions. One of the prerequisites for a quick and reversible smoothing of the skin is the number of amino acids present. In the natural aging process, the number and availability of these amino acids continuously decreases, so that smoothing and regeneration processes require a longer period of time or can no longer be reversible.
As a result, wrinkles initially remain dimly visible and then, as age progresses, become present without mimic movement. The following types of wrinkles 1. wrinkles are usually caused by a loss of volume. On the one hand, this is caused by insufficient fluid absorption in the sense of drying out the body, on the other hand, by drying out the skin from the outside.
2. gravity wrinkles of the skin are caused by tensile forces on the hanging parts of the body. 3. slack wrinkles are mostly caused by mechanical lying situations at night and4. Mimic wrinkles, as mentioned above, are caused by movements of the mimic muscles under the skin (laughing, crying, talking).
Wrinkles do not only result from a natural aging process but also from external influences. People who expose their skin to increased weather exposure, such as wind and rain, will experience earlier wrinkle formation than people who spend most of their time at home. In addition, the sun’s rays on the skin play an extremely important role in the formation of wrinkles.
UV radiation also causes the skin to form wrinkles more quickly through dehydration and degeneration processes. These wrinkles are usually not reversible. People who spend long periods of their lives outdoors often appear older due to increased skin wrinkling.
Furthermore, the use of UV lamps or solariums has an increased effect on the formation of wrinkles. This wrinkle formation is also not reversible. Wrinkle formation is mostly an expression of a natural aging process. A biological sense (in the sense of a protective mechanism) can only be recognized in the case of wrinkling caused by UV radiation, where the skin tries to make the skin surface rougher and less susceptible to sun and UV radiation by wrinkling.
