Actinic Keratosis is a scary name for something only somewhat scary, skin pre-cancer. I'm just lucky, and I'm honest with that word, to only have these types of problems right now. I did have one basal and two squamous cell carcinomas removed so I get a good check-up twice a year.
My problem right now is I've had this dry patch on my upper lip frozen with liquid nitrogen three times and it still won't go away. So my darling dermatologist, he is darling, too, will re-try something; a horrible treatment that went somewhat awry last time. Last time I used this cream I got flu like symptoms and my lips swelled twice the size of Angelina Jolie. I was miserable. He says it has to be and I can do it slowing using a third of the dose.
As a warning to anyone younger than a boomer, SUNSCREEN. Buy buckets of the stuff and don't leave the house without wearing a lipstick or lip gloss that has an SPF of fifteen or better. Seems like all that lip gloss we wore in the 80s did quite a bit of harm to the old lips. Who knew? I suppose putting baby oil on and sunbathing until we were a crispy shade of brown didn't help either.
