Sunscreen Myths and Facts: Applying sunscreen daily is recommended to protect against premature aging, skin pigmentation, and skin cancer. Nowadays, people are more concerned about their facial skin and are undergoing various treatments. Applying sunscreen to protect the skin has become very common. However, a concern for many is whether applying sunscreen reduces the effect of Vitamin D. According to skin experts, this belief is largely incorrect. Let's find out, does applying sunscreen daily really eliminate the effect of Vitamin D (which we get from sunlight)?

Does Using Sunscreen Every Day Lead to Vitamin D Deficiency?
According to skin experts, Vitamin D enters the skin when it comes into contact with ultraviolet rays from sunlight. Sunscreen is applied to the skin specifically to block and absorb UV rays. Therefore, many people believe that applying sunscreen daily reduces the production of Vitamin D in the skin. According to skin experts and dermatologists, this effect is not as serious as it is perceived to be. However, experts do say that many people don't know how to use sunscreen correctly. Therefore, they also advise on its proper use.
Disadvantages of Not Applying Sunscreen:
Skin experts believe that people often walk and travel outdoors in the sun. If sunscreen is not applied to the skin during this time, it can lead to problems such as skin cancer, premature aging, sunburn, and darkening of the skin. Experts also believe that the main cause of Vitamin D deficiency is not just sunscreen, but also people's lifestyle. Factors contributing to Vitamin D deficiency include spending most of the time indoors, air pollution, clothing choices, and an unhealthy diet. People who are deficient in vitamin D are advised by skin experts to spend more time in the sun. They are also advised to consume fortified foods, dairy products, eggs, and fatty fish, as well as take oral supplements.
