Why is UV radiation considered harmful?

What is skin aging?
Skin aging is a phenomenon where fibroblasts, which produce collagen and elastin fibers in the dermis, are damaged or lost, leading to a decrease in firmness and elasticity, causing wrinkles and sagging, and the aging of skin cells. It is said that 80 to 90% of the cause is ultraviolet light. For those concerned about skin aging, UV rays are nothing but "terror."
Another surprising fact is that your eyes can also get sunburned. When UV rays hit the nerves in your eyes, the brain sends a command to "protect the skin." This is because there is a mechanism that promotes melanin production as a defense reaction. Excessive melanin leads to hyperpigmentation and spots.
If you've been exposed to UV rays, you need both internal and external measures! Next time, we'll tell you about these countermeasures.
