Why Focus on Mitochondria in Skin Aging?
Skin aging involves multiple cellular processes, and mitochondria play a central role in maintaining cell vitality. Altered mitochondrial behavior contributes to hallmark aging mechanisms:
- Oxidative stress: Excess reactive oxygen species (ROS) damage cellular components.
- Inflammation: Chronic inflammatory signaling accelerates tissue deterioration.
- Glycation: Accumulation of advanced glycation end-products (AGEs) disrupts protein function.
- DNA damage: Mitochondrial dysfunction affects genomic stability and repair.
Assessing mitochondrial health allows for targeted evaluation of longevity and healthy aging strategies and claim validations.
