Talking about.. Beauty
Skin aging is a complex and multifactorial process that causes profound changes at the molecular level that result in the appearance of wrinkles and other visible changes in facial and body skin.
Aging involves every layer of the skin:
A slowing in cell renewal and a reduction in lipid production on the skin’s surface lead to dryness and skin roughness.
Collagen is the most abundant protein in the human body. Into the dermis it supports and protects the skin structure. Elastin contributes to the elasticity of the skin. From 25 years of age, there is an annual reduction in the production of collagen. This, in addition to the decrease of elastin, leads to a disorganization of the dermal tissue. Another important change is the reduction of hyaluronic acid, natural polysaccharide present in dermal layer, as a component of the extracellular matrix, responsible for the tonicity and levels of hydration of the skin.
In summary, the amount of important substances as collagen, elastin and hyaluronic acid decreases in the dermis: resulting in alteration of the connective tissue and the loss of elasticity that causes the cutaneous “sagging” typical of the most mature skin.
Furthermore, a reduced blood circulation is observed which results in a lower intake of nutrients and oxygen on the epidermis surface. This leads to a decrease in the rosy and shiny appearance typical of young skin.
The most visible changes in the deeper layers are connected to the size and number decrease of fat-storing cells (adipocytes) in the adipose tissue.
