Influences on Skin and Intrinsic Aging: Biological, Environmental, and Therapeutic Insights

Area of Science:

• Dermatology
• Gerontology
• Cellular Biology

Background:

• Aging is a natural process involving physiological decline, particularly affecting the skin.
• Skin aging results from intrinsic (genetics, metabolism) and extrinsic (environment, lifestyle) factors.
• Understanding these aging drivers is crucial for healthy aging and skin health management.

Purpose of the Study:

• To review key intrinsic and extrinsic factors influencing skin and intrinsic aging.
• To provide a comprehensive understanding of the underlying mechanisms of skin aging.
• To identify elements contributing to the aging process.

Main Methods:

• A systematic literature review of peer-reviewed journals, clinical studies, and scientific reviews.
• Focus on studies published within the last two decades concerning intrinsic and extrinsic skin aging mechanisms.
• Inclusion criteria prioritized relevant studies, with quality assessed by design, sample size, and methodology.

Main Results:

• Intrinsic aging drivers include cellular senescence, genetics, telomere shortening, oxidative stress, hormonal changes, metabolic processes, and immune decline.
• Extrinsic aging is significantly impacted by UV radiation, pollution, diet, smoking, alcohol, sleep, and skincare.
• The interaction of these factors accelerates aging, causing wrinkles, reduced elasticity, and pigmentation changes.

Conclusions:

• A thorough understanding of intrinsic and extrinsic skin aging factors is vital for effective prevention and intervention.
• A multifaceted approach combining lifestyle changes, advanced skincare, and new therapies is recommended.
• Mitigating aging effects promotes healthier, more resilient skin.
