Abstract
BACKGROUND
Actinic keratosis is regarded as a carcinoma in situ by some dermatologists and its incidence continues to rise. Exposure to ultraviolet (UV) radiation is considered to be an important risk factor for developing these pre-malignant lesions. DNA repair enzymes have been shown to reverse sun-damage, resulting in reduced rates of actinic keratoses and non-melanoma skin cancers in specific patient populations.
METHODS
Seventeen patients were evaluated for differences in actinic keratoses following topical application of T4N5 liposome lotion over 48 weeks.
RESULTS
Compared to baseline, a statistically significant reduction in the number of actinic keratoses was seen following the treatment period.
DISCUSSION
This study suggests that DNA repair enzyme creams effectively reduce the number of actinic keratoses in normal individuals with moderate-to-severe photodamaged skin.
