The literal translation of the inherent characteristics of skin tissue is our common skin texture. It is accompanied by human beings at birth. It is composed of undulating skin grooves and skin crests, which are mostly fixed polygons and almost unchanged. Looking directly at the bare skin, you can see the intricate, chaotic textures, as well as the fine hairs of heavy or light color. However, with the passage of time, people continue to age, and the skin also gradually ages naturally. At the same time, the skin that is often exposed will also suffer from external stimuli such as environmental pollution, and continue to be injured, and the rate of damage to the stratum corneum cells will change. The number of skin grooves and skin ridges is changing, and the relatively stable shape also appears cross-bonded, the number decreases, and the surface area continues to expand, so the skin becomes wrinkled and rough.
Typically, before the age of 25, the surface of the skin is smooth, bright, and elastic. After that, however, the skin begins to age gradually and the physiological symptoms usually change.
1. Skin moisture and skin barrier
Most of the researches on rough skin focus on the functions of the stratum corneum, such as the function of water retention ability and the function of skin barrier. Such as the study of moisture, natural moisturizing factors, and lipid changes between stratum corneum cells. Moisture loss is severe, causing the skin to become matted and grainy. The shedding of epidermal cells is disordered, resulting in the production of dandruff and scales. The moisture content of the skin is closely related to the moisture, luster and fineness of the skin. The smooth, more watery stratum corneum reflects regularly to create a luminous radiance, while the dry, scaly stratum corneum reflects in a non-specular way that makes the skin look gray. With low moisture content in the skin, the skin becomes dry and rough, and the skin is dull.
Skin with reduced barrier function is like a broken umbrella. Not only does endogenous water evaporate easily, but external stimuli are easy to invade, and inflammation is also prone to occur. Such as skin problems related to inflammation: itching, roughness, peeling, itching, redness, etc. Recurring skin problems caused not by skin type but by chronic inflammation within the skin.
The photoaging epidermis showed repairing thickening when the damage was mild, and atrophy when the damage was severe. The cells of the basal layer were changed by obvious atypia, and there were a large number of dyskeratotic cells.
2. The dermis loses its elasticity
Skin roughness is closely related to skin elasticity. Skin elasticity decreases, skin laxity or wrinkles appear, and skin roughness increases. Fibroblasts are the most important cellular component in the dermis of the skin and play an important role in the synthesis of secretory fibers and extracellular matrix. It plays an important role in tissue wound repair. With age, the thickness of the skin decreases as the elastic fiber content in the skin gradually decreases. Skin aging is prominent, which can be realized as dry and rough skin, increased and deepened wrinkles, loose skin, and decreased elasticity. Age is accompanied by a decrease in the skin’s farther protein content, a lack of firmness in the skin, and an increase in the depth of skin texture leading to the appearance of wrinkles.
So before the skin problems are formed, we still have a lot of things to do. For example, the skin analyzer can help us slow down or solve the skin problems to a certain extent before the skin problems fully appear!
