I think it depends on what your tear drop looks like? If you have a well developed tear drop and then just going with the outer and middle heads will work good.
I tried going in my tear drop with a bottle I had extra and had to stop, that was a painful area for me and I have Syntherol'ed most body parts here and there to see how they reacted.
Kinda one reason I didn't want to do the tear dro.. I hheard it's painful. I guess I can to the others and see how it goes and looks. I'm not going nuts with it just want a bit more sweep
