Liquid rhinoplasty, also known as non-surgical rhinoplasty, is a cosmetic procedure where injectable dermal fillers (typically hyaluronic acid-based fillers) are used to reshape and contour the nose without surgery. It is used to smooth out bumps, lift a drooping tip, or correct asymmetries.Nasolabial folds are the lines or creases that run from the sides of your nose down to the corners of your mouth, commonly known as smile lines or laugh lines. These folds deepen over time due to aging, facial expressions, and loss of skin elasticity.
