Source of Skin Aging

telomere

As we age, it’s a given that our skin will also age. Many factors can accelerate the aging of our skin, such as exposure to ultraviolet rays, smoking, and an unbalanced diet. What causes our skin to age, and what is the root of the problem?

Skin aging is actually the result of aging skin cells, which reduces the skin’s repair ability. Metabolism slows down, the accumulation of the stratum corneum increases, and collagen decreases, all of which are consequences of aging cells. From a surface level, age spots, loose skin, and fine lines are obvious signs of aging skin. The question is, why do cells age?

Scientists have found that “telomeres” are related to the lifespan of cells. The human body is composed of different cells, which means that telomeres are related to human lifespan. Simply put, telomeres are repeated DNA sequences at the ends of chromosomes that maintain chromosome integrity. Every time a cell divides, the telomeres shorten. When the telomeres shorten to a certain extent, they can no longer maintain the stability of the chromosomes, and the cells eventually die. Therefore, telomeres are closely related to cell aging. In general, the older the cell, the shorter the telomere.

Are there external factors that accelerate the shortening of telomeres? Yes, ultraviolet rays, smoking, and an unbalanced diet all have a negative impact on telomeres. For example, ultraviolet rays can damage DNA and shorten telomeres. In addition, smoking increases oxidative damage to DNA, thereby shortening telomeres. So, the root cause of skin aging is the shortening of telomeres!

If telomeres no longer shorten, will cells stop aging? There is currently no method to lengthen telomeres. Some products claim to be effective in lengthening telomeres, but consumers should remain skeptical until their evidence is sufficient before considering a purchase. While the concept of “anti-aging” skin may not be entirely fictional, we still need to pay attention to our diet, engage in regular exercise, avoid smoking and alcohol, and use sunscreen properly to slow down the aging process.
