I'm on day eight applying Carac to area above upper lip from the defining edge of lip to nose. On the bottom lip, I'm applying surrounding area and about 1/2 of lip surface including the corners. At this point, the area above the lip and the corners are the most sensitive, though it is all unsitely, to say the least.
Are you only doing the lip surface? If so, from what I'm seeing right now, you will probably experience extreme dryness and possible cracking. I am using Aquaphor which seems to be most effective on the lip surface.
I am also treating my hands and forearms (day 21). Unfortunately, I have to say the lip area is much more sensitive.
FYI; I have had three PDTs on all areas (applying Levulan Kerastick followed, in one hour, with the IPL and Vbeam lasers). This is a costly procedure that is said to have less down time and optimal cosmetic results. There was less down time, however in my case, the AKs were virtually unaffected and a biopsy shows that one on my bottom lip is quickly heading for the Squamous stage (so much for vanity!).
As far as your concerns about appearance (believe me, I get it!), if your treatment is confined to a small area, it will be obvious that you are undergoing a skin treatment (particularly with a layer of greasy ointment). You will be surprised how many people will say they have been thru it or know someone who has.
I will be happy to give you up-dates over the next two to three weeks. I will also be watching to see if anyone else has treated the lips.
Good Luck,
Carole
