There are two types of skin aging: chronological aging and photoinduced aging. Skin aging begins at the cellular level, in this case we speak of chronological aging.
Another type of aging that is photo-induced depends on external factors the UV rays.
What happens in skin aging?
Aging begins at the cellular level and is the result of free radical damage on the vital structures of the cell and various tissues.
Reduction of the synthesis of proteins present in the skin that give elasticity and tone to our skin such as collagen and elastin.
The loss of elasticity and tone of the tissues leads to the formation of a rougher skin appearance.
Causes of skin aging
Physiological phase: natural cell aging process.
UVA rays are able to penetrate the innermost layers of our skin and cause damage to cells.
Very small particles that are able to penetrate our skin. The work cells do to eliminate them causes premature aging.
Reduces the supply of oxygen to tissues that age prematurely.
A diet low in nutrients results in a less luminous and hydrated skin.
The drop in estrogen due to menopause accelerates skin aging.
