Bunny lines are the fine wrinkles that appear when you scrunch up your nose, such as when you laugh or smile deeply. These lines appear straight or somewhat diagonally on either side of the nose just beneath the bridge, and as you age, they eventually hang around in the form of fine lines even when your face is relaxed. They might be obvious, or they might be nothing more than tiny creases. When you’re young, this isn’t a huge concern. Your skin is elastic and bounces back readily. However, as you age, your skin loses much of its elasticity and those lines become more pronounced. Although it’s said to promote some skin elasticity by boosting the production of collagen and elastin in the skin, it primarily works on facial muscles in the manner described above. This makes it an ideal way to prevent the development of fine lines and wrinkles because it limits the depth of expression.
