Histological Comparison of Two Cryopeeling Methods for Photodamaged Skin

Figure 1

Patients received the treatment of cryopeeling using the PS for one forearm (a) and using LN for the other forearm (b), randomly. The cryopeeling was performed by applying the freezing substance with brush movements along the extension of the forearm until the area was frozen. After this, actinic keratoses lesions were individually treated.
