[Aging skin: physiological bases, preventive measures and therapeutic modalities]

Area of Science:

• Dermatology and Gerontology
• Skin Physiology
• Aging Research

Context:

• Increasing average lifespan highlights visible signs of skin aging.
• Growing interest in understanding and treating age-related skin conditions.
• Cutaneous aging is influenced by intrinsic genetic factors and extrinsic environmental factors.

Purpose:

• To review the physiological changes associated with cutaneous aging.
• To outline current treatment modalities for common age-related skin concerns.
• To provide an overview of the complex factors contributing to skin aging.

Summary:

• Cutaneous aging involves intrinsic and extrinsic factors, leading to decreased cellular components and immune system changes.
• Visible signs include wrinkles, elastosis, and senile xerosis.
• Treatments encompass emollients, topical acids, injectables, and laser resurfacing.

Impact:

• Informs dermatologists and researchers on the multifaceted nature of skin aging.
• Guides the selection of appropriate interventions for age-related skin conditions.
• Contributes to managing the aesthetic and health impacts of aging skin.
