‘Skin anti-aging scholar’ Jeong Jin-ho, professor at Seoul National University Hospital
‘Healthy skin that protects my brain’ book published
“Sunscreen, a protector for brain health”
“Maintaining healthy skin can be the secret to maintaining a clear mind, good judgment, and a calm mind.”
Jeong Jin-ho, professor of dermatology at Seoul National University Hospital, published a medical book containing the message that ‘healthy skin creates a healthy brain.’
According to Professor Jeong’s book ‘Healthy Skin That Protects My Brain’ on the 16th, he writes about ▲ ultraviolet rays that change brain function ▲ skin aging that has a negative impact on brain function ▲ reduction of subcutaneous fat, which inhibits adiponectin production. It contains the relationship between skin and brain, including ultraviolet rays that have a negative impact on skin and brain health; ▲ ‘ABO blood type sugar’ that strengthens the skin barrier and controls inflammation; ▲ various causes of skin aging and ways to prevent skin aging.
Ultraviolet rays affect not only the skin but also brain function. Through mouse experiments, Professor Jeong found that ultraviolet rays increase the stress hormone cortisol in the skin, reducing neurogenesis in the hippocampus, which controls memory and learning, and inhibiting the formation of synapses, which are connections between nerves, thereby reducing memory and cognitive ability. proved.
Professor Jeong also discovered that ultraviolet rays excessively increase the neurotransmitter dopamine, inhibiting the creation of new neurons in the hippocampus, thereby reducing memory in mice. This is why thoroughly blocking ultraviolet rays is very important not only for skin but also for brain health.
Professor Jeong said, “Hormones and physiologically active substances pathologically produced in diseased or aged skin reach the brain through the blood and reduce brain function. To protect the brain from ultraviolet rays, apply sunscreen to exposed body parts. “You must thoroughly block ultraviolet rays by thoroughly applying sunscreen and wearing sunglasses,” he said.
Skin aging also has a negative effect on brain function. When the skin ages, it dries out and cytokines, inflammatory substances produced in the skin, flow into the blood, causing mild inflammation. This inflammation accelerates the aging of our body, including the brain. In fact, it has recently been revealed that when cytokines act on the brain, they cause memory decline and cognitive function impairment observed in the elderly.
To maintain healthy brain function, you must apply moisturizer to your skin. Professor Jeong said, “Improving dry skin improves the brain health of the elderly,” and added, “If moisturizer is applied consistently, the cytokines that increase inflammation in the elderly’s blood are reduced and the rate at which the elderly’s cognitive function deteriorates is slowed. “I lose,” he said.
Even if the adiponectin protein produced by fat cells becomes insufficient due to ultraviolet rays, it can have a negative impact on the health of the skin and brain. Ultraviolet rays reduce subcutaneous fat and inhibit the production of adiponectin produced in subcutaneous fat, causing various skin diseases such as psoriasis, sensitive skin, keloids, and skin aging. Adipotectin deficiency is known to affect brain function, causing depression, memory loss, and cognitive dysfunction.
In addition, Professor Jeong introduces various factors that promote skin aging, such as active oxygen, ultraviolet rays, heat aging, menopause, smoking, fine dust, and skin inflammation, and how these factors can be managed and prevented.
Professor Jeong, who retired at the end of August, is a world-renowned scholar in the field of skin anti-aging who has been conducting continuous research for 30 years to uncover the secrets of skin aging. He served as head professor of dermatology at Seoul National University College of Medicine, director of the Department of Dermatology at Seoul National University Hospital, and director of the Institute for Aging and Aging Society at Seoul National University. He has also served as a doctor affiliated with the International Federation of Dermatological Societies (ILDS), which has dermatological societies around the world as members.
Professor Jeong said, “Healthy skin is essential for maintaining a smart brain and a healthy mind,” and added, “I hope that keeping your skin healthy will help you live a healthy life until you reach 100 years old.”
