Acne vulgaris is a chronic, inflammatory disease accompanied by lesions affecting the structure of the skin. Chemical peels are one of the methods of reducing acne vulgaris. There is still a lack of quantitative methods of assessing impact of cosmetic procedure on the skin. Skin condition depends on skin texture characterization; therefore, the analysis that provides data about the textures can be helpful in assessing the effectiveness of cosmetic treatments.
The study involved 24 volunteers with acne lesions. Each participant underwent 4 treatments using chemical peels at two-week intervals. Before, during and after procedure clinical photography were made. To assess effectiveness of chemical peeling in acne lesion reduction, we were used gray-level co-occurrence matrix (GLCM) analysis. Qualitative assessment of acne severity was made by 12 experts in dermatology.
After a series of treatments, the GLCM contrast value decreased in each area of the face, and the GLCM homogeneity value increased, which means that the number of acne lesions was reduced. Expert assessment according to the IGA scale confirms the effectiveness of therapy with both salicylic and glycolic acid and pyruvic acid.
The results of this study prove that GLCM analysis is a useful tool for assessing the effectiveness of chemical peel treatments. It can also be used for quantitative assessment of skin texture.
寻常痤疮是一种慢性炎症性疾病,伴有影响皮肤结构的损害。化学剥脱术是减轻寻常痤疮的方法之一。目前仍缺乏评估美容手术对皮肤影响的定量方法。皮肤状况取决于皮肤纹理特征;因此,提供有关纹理数据的分析有助于评估美容治疗的效果。
该研究纳入了24名有痤疮损害的志愿者。每位参与者每隔两周接受4次化学剥脱术治疗。在治疗前、治疗期间和治疗后进行临床拍照。为评估化学剥脱术在减少痤疮损害方面的效果,我们采用了灰度共生矩阵(GLCM)分析。由12名皮肤科专家对痤疮严重程度进行定性评估。
经过一系列治疗后,面部各区域的GLCM对比度值降低,GLCM均匀性值增加,这意味着痤疮损害数量减少。根据IGA量表进行的专家评估证实了水杨酸、乙醇酸和丙酮酸治疗的有效性。
本研究结果证明,GLCM分析是评估化学剥脱术治疗效果的有用工具。它还可用于皮肤纹理的定量评估。
