Histological Comparison of Two Cryopeeling Methods for Photodamaged Skin

Table 1

Histological findings are summarized. Epidermal and Grenz zone thicknesses values were obtained by average of three measurements. Pigment intensity score was based on a weighted average considering intensity and distribution of pigment. The intensity of pigment decreased after PS treatment (P = 0.025).
