Being exposed to sun rays without protection considered as an important factor for early signs of aging.
It has been proven many times in different scientific studies in different parts of the world that UVA and UVB rays are the main cause of wrinkles, hyperpigmentation, loss of elasticity and collagen, deterioration of skin texture and many more. For example, the World Health organization's report "Sun Protection: Essential Teaching Resource" is dedicated to teaching people all about the health risks of UV radiation and how to protect themselves.
In a study showing the negative effects of sun rays, twins exposed to different degrees of sun rays were discussed. As a result of the research, it was determined that the twin, who was more exposed to the sun's rays, had a skin tissue 11.5 years older than the other. Another study published by the American Society of Photobiology found that people suffer only 23 percent of sun damage by the age of 18, and are affected by about 10 percent more each decade thereafter.
Considering all these researches and the importance that dermatologists give to sun protection, using sun protection is the most important step in the care routine to prevent the destruction of collagen and elastin levels in anti-aging care, to prevent wrinkles and sagging formations, to prevent skin tone differences and to fight many signs of aging.
