Treatment of actinic keratosis will depend on the number of actinic keratosis that you have and a consultation with your dermatologist.
As we discussed earlier, not all actinic keratosis lead to squamous cell carcinoma. And some people feel comfortable leaving them untreated. However, most dermatologists recommend that they are treated as ten percent conversion rate is high. If you only have one or two lesions, liquid nitrogen spray is all that's needed to treat actinic keratosis.
For more extensive lesions, oftentimes, certain medicated creams like Epudex or Aldara may be used to treat actinic keratosis. The treatment's regimen will be more prolonged, as long as 16 weeks. And you will need to see your dermatologist frequently to make sure you are tolerating the treatment.
