Sagging facial lines caused by the summer heat, Shurink lifting laser effects and pain

Perhaps because it is summer and the weather is so hot and humid, my facial skin feels dry and sagging, and my jawline seems less sharp and more indistinct than before. Every time I look in the mirror, the skin around my mouth and deep cheeks appears to have sagged slightly, so I am seriously considering a lifting procedure. I have heard that the Shurink lifting laser is affordable and popular, so I am wondering if it is effective for someone like me who doesn't have excessive cheek fat but simply wants to smooth out the overall skin elasticity line. Also, I have heard that lifting lasers can cause quite a bit of bone-shattering pain; I am curious if it is tolerable even for someone who can't tolerate pain well, provided that anesthetic cream is applied for a long time.
