What you are describing sounds more like a texture problem than just loose skin. often times people will develop various types of bumps under the eyelids. These can be enlarged oil glands, or growths known as syringomas or other types of growths less commonly.
Thermage can provide some skin tightening under the eyes but does little for true textural abnormalities. The beauty of Thermage is, of course, that there is no associated down time. One laser procedure that does tighten skin and will smooth out texture problems is Laser Resurfacing with either a CO2 or fractionated CO2 such as the Total FX/Active FX laser. This does have associated downtime of 5-10 days depending upon the energy settings used but produces wonderful results.
There may be other options sucha s other lasers or chemical peels as well depending upon the exact cause of your "roughness" so you should see your dermatologist to have these areas evaluated in order to determine the best treatment for you.
