Actinic keratosis are gray-to-pink-to-red, scaly spots called actinic keratosis.

These usually occur on your face, scalp and the backs of hands. They start as flat lesions that feel like sandpaper, but later may develop a hard, wart-like surface.

Between 1% to 3% can progress to skin cancers within 10 to 20 years if ignored, and may need to be removed surgically.


In the early stages they can be removed by applying a chemotherapy cream or freezing with liquid nitrogen. Hydroxy acids and strong copper peptides often slowly remove these lesions. These should not be confused with skin melanomas which do not appear to be associated with sunlight exposure.


See SUNTAN SCIENCE for more information on sunlight and cancer and the possible anti-cancer effects of sunlight exposure.


What cannot be seen in the photograph:
The Actinic Keratosis area was very raised and crusty. Currently, not only has the lesion flattened considerably, at the surface the cells appear much better organized.


Results achieved with the use of a high concentration GHK copper peptide serum and micro needling. Microneedling consisted of three sessions with a .5ml micro needle every 6 weeks.


Time period: Approximately 5 months - "Before" photo was taken in January of 2014 / "After" photo was taken in May of 2014 right before the 4th needling session.
