Detailed answer

Laugh lines, also known as nasolabial folds, are primarily caused by the breakdown of collagen and elastin in the skin as we age. While moisturizers can help improve the hydration level of the skin and temporarily plump up the laugh lines, they cannot permanently reduce or eliminate them. To effectively reduce laugh lines, it is important to incorporate other skincare products or treatments that stimulate collagen production and improve skin elasticity, such as retinoids, peptides, or hyaluronic acid. Additionally, certain lifestyle choices, like avoiding excessive sun exposure and following a healthy diet, can also contribute to maintaining firm and youthful skin.
