I have questions about nasolabial fold procedures.

Even when losing weight, the flesh on the front cheekbones and cheek area tends not to decrease easily. As the cheek fat or front cheekbone fat becomes prominent, nasolabial folds develop, but pressing on the cheek fat makes the nasolabial folds less visible. Could liposuction of the cheek or cheekbone area help alleviate this? Or would contour injections be better? Also, are contour injections permanent? Or do they fade after a few months like Botox?
