I dive year round , below 55F i dive dry , Below 45 I dive dry in a crushed neo drysuit, i wear a henderson goldcore drysuit hood, and on my reg (aqualung glacia) there is a lip shield, i think i comes included with and aqualung cold water reg, however i have seen them online for about 15 $ . I ordered 4 more this winter for stocking stuffers for my cold water dive buddies. They love them , and i cannot say enough, they do make a tremendous diffference in keeping your lips from falling off...lol. the only exposed portion of my body is two small parts of my cheek about the size of a quarter. After about 60 seconds of exposure the tingling of the frigid water on my cheeks goes away, but i do agree , i cannot stand cold lips. I ordered mine from an aqualung dealer, i would assume like my local dive shop any aqualung dealer should be able to get them for you . I have seen them fit on many other brands of regulators as well, despite being an aqualung product. or you could buy them online, do a google search for lip shields. I also dive full face masks, but truly prefer the air consumption of my reg, and am not really bothered by exiting the water with rosy cheeks!
