Is carboxytherapy a good alternative method in the removal of various skin defects?

Carbon dioxide is a physiologic compound present in our body, mainly as a result of cellular metabolism. The frequency of carboxytherapy use by dermatologists and cosmetologists increased significantly in the second half of the 20th century due to the fact that it improves blood circulation within skin tissues. This article focuses on the use of carboxytherapy in case of various skin problems, such as stretch marks, scars, loss of elasticity, redundancy of fatty tissue, cellulite, morphea, and alopecia. The review of sparse studies that are available indicate increasing interest in this method.

Cutometric assessment of elasticity of skin with striae distensae following carboxytherapy.

OBJECTIVE: The aim of the study was to evaluate the effectiveness of carboxytherapy in the treatment of striae distensae. Additionally, discomfort and side effects associated with the treatment were assessed. MATERIALS AND METHODS: This study involved 15 women aged 22-40 years. They underwent 3 sessions of carboxytherapy at one-week intervals. Treatment was performed in skin area within stretch marks located on stomach, buttocks, and thighs. Cutometric probe was used to evaluate skin elasticity. Four measurements were performed-immediately before each treatment and one month after the last session. Photographic documentation was made before and after a series of treatment to perform clinical evaluation of changes in skin condition. RESULTS: Statistical analysis of results obtained with the use of Cutometer (R2 and R8 parameters) demonstrated that carboxytherapy significantly improved skin elasticity within stretch marks (P < .05). The analysis of photographic documentation revealed 58% improvement in stretch mark visibility. The width and length of stretch marks decreased, and their color became more like the natural color of the skin. Carboxytherapy is associated with moderate pain/discomfort. The occurrence of hematoma is the main side effect of this procedure. CONCLUSIONS: Carboxytherapy seems to be an effective method of reducing stretch marks. This procedure is safe, and it can be performed without the risk of complications. Moreover, it does not require special postoperative convalescence. Photographic documentation is a method of assessment of aesthetic procedures effectiveness, which is complementary to other objective methods (eg, the use of MPA probes).

Paxillin and its role in the aging process of skin cells.

Morphology of senescent cells is constantly changing at the molecular level, which in turn leads to disruption of their function. It is connected with reduced ability to synthesize extracellular matrix (ECM) and leads to the dysfunction of integrin adhesion molecules and adhesion clusters. In skin, these factors cause a loss of communication between the extracellular matrix and fibroblasts. This contributes to the appearance of signs of aging. The aim of this study is to draw attention to the very important molecule such as paxillin, which is an adaptor protein with mass of 68 kDa. This family of proteins includes Hic-5, PaxB and leupaxin. Paxillin binds to actin-binding proteins such as vinculin, actopaxin, and kinases (e.g. Integrin-linked kinase (ILK)). Moreover, it plays an important role in the integrity of the matrix, because it transduces transmembrane signaling between integrins and growth factors. Paxillin is a scaffold protein, activating the arrangement and organization of the cytoskeleton. Signaling through paxillin affects the long-term changes in gene expression, cell proliferation, and organization of the ECM. Correct functioning of the ECM is important for the wound healing processes and regeneration of tissues or tissue repair. Decrease or lack of paxillin expression results in changes in the structure and integrity of the ECM, which are manifested by aging of cells and organs. Restoration of the cellular matrix connections would be a significant element in the processes related to the anti-aging activities.
