Sleep creases are no laughing matter. As those of you who own one know, cotton pillows can have you waking up with lines that appear etched onto your face come sunrise. And while we hate to break it to you, those marks could be sabotaging your skin’s health. Yes, over time, the folds on your pillowcase can cause wrinkles due to dryness and irritation during even the most restful sleep.

Despite a healthy diet, exercise, and a lot of sleep, stress, anxiety, and hormonal changes can leave our skin feeling a little lackluster or dull. Collagen loss is one of the side effects of aging, and can cause the skin to appear hollow and tired. That's where face masks with collagen come in handy. According to Dr. Rachel Nazarian, MD, there is no evidence that applying collagen topically to skin will stimulate collagen under the skin or help with anti-aging.

You shouldn't let concerns about wrinkles around the mouth prevent you from enjoying the moments of happiness and humor that often result in belly laughs. Yes, we know that smiles and laughter stretch the skin around your upper lip, which causes wrinkles over time,1 but that doesn't mean you should stop yourself from living your life with unapologetic joy.
