Wrinkles form mainly due to two reasons: loss of elasticity and reduced moisture. When we're young, our skin has a lot of collagen and elastin, which are like the building blocks that keep our skin tight and elastic. But as we get older, our body produces less of these substances, making our skin less flexible. Cumulative exposure to UV radiation damages the collagen and elastin fibers, thus slowing down skin cell turnover and leading to a dull, aged appearance. Also, over time, our skin loses moisture, which can make it look dry and wrinkled. There are a few key ingredients you should look for to help slow down the skin aging process. First of all, daily SPF 30+ sunscreen is crucial to prevent further damage to the skin from the sun's harmful UV rays. The tint in tinted sunscreens provides extra sun protection as well. Retinoids are derivatives of vitamin A that help stimulate collagen production can reduce the appearance of wrinkles. Apply this at nighttime. Hyaluronic acid is a substance naturally found in the skin that helps it retain moisture. Using moisturizing creams with hyaluronic acid can help keep your skin hydrated and plump. You can apply this in the morning and night. Lastly, vitamin C is an antioxidant that helps protect the skin from damage caused by free radicals and also helps stimulate collagen production. Apply this in the morning. By using a combination of these ingredients in your skincare routine, you can help keep your skin looking youthful.
