Winter is the time of year when you should work harder to avoid wrinkles and dry skin. Apply sunscreen to keep your skin radiant. Winter weather can be extremely drying and taxing on the skin. Fortunately, sunscreen has been shown to prevent aging. In addition, these brand-new anti-aging agents may be of assistance. According to Dr. Jaber, UV rays damage collagen and elastin in the skin, accelerating the appearance of fine lines and wrinkles. There have been several studies that have demonstrated that using sunscreen regularly has anti-aging effects. However, the most effective of these studies was a 2013 Australian study. Over four years, researchers compared the aging of the skin of 900 Australian men and women. They discovered that those who applied sunscreen every day did not show any signs of aging! Overall, they were 24% younger than those who did not apply sunscreen. The fact that the participants were on average 39 years old demonstrates that it is never too late to start using sunscreen. Choose a sheer sunscreen with broad-spectrum protection and other anti-aging properties, such as SkinCeuticals Physical Fusion UV Defense SPF 50.

SPF stands for sun protection factor. A  higher SPF is preferable in this regard, it will not provide you with extended protection."Using a high SPF like 100 can give you a false sense of protection because people think it lets them stay in the sun for longer without having to reapply."You must reapply sunscreen every two hours, regardless of whether you use SPF 30 or SPF 100."The UVA protection, on the other hand, decreases with SPF. The sun's UVA rays, which are responsible for skin aging, hyperpigmentation, and more aggressive skin cancers like melanomas, are less protected by sunscreens with SPFs above 60.
