The aging process of the skin is a natural occurrence and progresses differently from person to person. One of the major causes of skin 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.
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.
Typical changes include a loss of moisture and elasticity, causing tautness, and resulting attention and protection with enhanced skin care requirements.
