The aging process of the skin is a natural occurrence and progresses differently from person to person. The signs and appearance of aging and maturing skin will depend on your skin type and the type of external and internal environmental stresses your skin endures.
One of the major causes of aging is “oxidative stress.” This relates to damage to our DNA, proteins, and lipids (fats) caused by oxidants, which are highly reactive substances containing oxygen. These oxidants are produced normally but also result from inflammation, infection, and consumption of alcohol and environmental pollution.
The majority of age-dependent changes that occur in our skin happen in the dermis, which can lose from 20-80% of its thickness during the aging process. This is the result of changes in the fibroblasts, the cells responsible for collagen, elastin and glycosaminoglycan (GAG) biosynthesis. Not only is the collagen and elastin produced at a slower rate, which impacts the skin’s inability to repair itself, but the organization of the protein also changes, affecting the skin’s structure.
Most commonly changes to the skin appear when people reach their mid-twenties, their skin begins to change, and depending on its constitution, as well as external influences, signs of ageing will develop sooner or later. Typical changes include a loss of moisture and elasticity, causing tautness, and resulting attention and protection with enhanced skin care requirements.
Collagen play a crucial role and is what makes your complexion firm, plump, and youthful. This protein makes up 75 to 80 percent of your dermis.
