Do you consider yourself to be an upbeat, optimistic person? Are you happy with where your life is right now? Your face might be telling people otherwise, according to NBC News. Specifically, the signs of aging may be leading individuals to think that you’re sad and angry, even when you’re not!

At the annual meeting of the Association for Psychological Science, a study was presented that looked at how people generally view others and judge them based on their facial appearances. Creases and furrows led many people to think that the faces they were looking at belonged to older, sad individuals, even though this wasn’t necessarily true. Now that you’ve heard the science behind the assumptions, you likely don’t want to be one of these misjudged people!

There are a couple of ways you can fight signs of aging on a daily basis. When you moisturize, try to use a lotion that contains SPF to protect your skin from ultraviolet rays. The American Academy of Dermatology claims that wearing sunscreen every day can reduce the development of wrinkles. Woman’s Day magazine notes that staying hydrated and drinking plenty of water might also help you combat fine lines.
