This video discusses the topic of autophagy and how it can help to improve skin health, particularly by reducing sagging and wrinkles.
The video explains that autophagy is a natural process in which the body breaks down old or damaged proteins and other substances in the cytoplasm of cells, recycling the breakdown products for important cell functions.
Autophagy is particularly active during periods of stress or starvation, and it can help to destroy bacteria and viruses that cause infection and prevent normal cells from becoming cancerous.
The video goes on to explain that autophagy is important for maintaining skin health, as aging fibroblasts (cells in the connective tissue that produce collagen and other support fibers) can become clogged up with waste products over time, rendering them unable to produce collagen and keep the skin tight and healthy.
The video cites several scientific studies that have investigated the effects of autophagy on loose skin, with one study from 2014 finding that a slowdown in the autophagy process can lead to the deterioration of skin and dermal integrity, resulting in wrinkles and sagging.
The video then outlines several ways to induce autophagy in the body and improve skin health, including intermittent fasting (limiting eating to a certain window of time each day), caloric restriction, exercise, and hormone optimization (particularly for women, as estrogen, progesterone, and testosterone all play a role in skin health).
The video emphasizes that autophagy can help to produce collagen, elastin, and other support fibers in the skin, resulting in a more finely-tuned machine ready to take on the aging process.
The video concludes by stating that autophagy is scientifically studied and that the presenter sees the benefits of autophagy in his clinical practice every day.
