How to Minimize Smile Lines, According to Experts

    Isn’t it ironic (and incredibly frustrating) that the more we smile and laugh, the more pronounced our smile lines become? Known as smile lines, laugh lines or nasolabial folds, these lines extend from either side of the nose down to the corners of the mouth. But, facial expressions aren’t the only causative factor. “The loss of facial volume that occurs with aging is a big culprit,” says Washington, D.C. dermatologist Tina Alster, MD. “Essentially, the facial foundation sags and leads to development and deepening of the nasolabial folds. Facial volume loss can be caused by intrinsic aging, genetic predisposition, rapid weight loss, and certain medications.”

    Other factors that can cause more pronounced nasolabial folds or laugh lines include smoking, environmental pollutants and sun exposure. UV exposure speeds up the aging process, leading to wrinkles and an uneven skin texture,” addsDallas dermatologist DiAnne Davis, MD. There’s a chance that one smile line may look deeper than the other as well. This tends to occur on the left side of the face, which is exposed to more sun while driving and can experience more collagen damage.
