The use of Carboxytherapy alone or in combination with fractional CO2 laser for facial rejuvenation: A splita??face comparative study
摘要： Background A wide variety of minimally invasive treatments are available for skin aging. Recently carbon dioxide therapy (CDT) or carboxytherapy was used in many cosmetic indications including facial rejuvenation. Objective To compare the efficacy of CDT alone versus combined CDT and fractional CO2 laser in management of facial aging. Methods Twenty-Five female patients with bilateral and symmetrical facial aging were included in the study. The right (Rt) hemiface received 8 sessions of CDT whereas the left (Lt) side was treated with combined technique (6 sessions of CDT and 2 sessions of fractional CO2 in between. Clinical and objective evaluation using 3D skin analysis, histological and morphometric analysis were performed. Results Clinical evaluation demonstrated that all patients (100%) were satisfied with no significant difference between both sides of the face (p>0.05). Regarding texture and pigmentation improvement, the Lt side (combined) showed significant improvement compared to the Rt side (p<0.05). Using Antera 3D camera, there was a significant difference (p<0.05) in 3D improvement percent in textural changes while there was no significant difference (p>0.05) in the 3D percent of wrinkles improvement between both sides. The Lt. side showed more significant increase in epidermal thickness after treatment when compared to the Rt. side (p<0.05) with evident neocollagen formation. Conclusion Carboxytherapy is an easy, safe, simple and a relatively effective method for facial rejuvenation with minimal downtime. Better results were achieved when used in combination with fractional CO2 laser.

Photocarcinogenesis & Photoprotection || Ultraviolet Radiation (UVR): An Introduction
摘要： Radiant energy of sun is essential to perform metabolic processes of all flora and fauna on the earth. The electromagnetic radiations (EMR) emitted by sun extend from very long wavelength radiation, such as radiowaves (A ″′ 3 × 108 m), to very short wavelength radiation, such as cosmic rays (A ″′ 3 × 10?19 m). The EMR reaching at the earth surface contains wavelength from 290 to 4000 nm. However, the UV portion covers from 200 to 400 nm. The range from 200 to 400 nm is often arbitrarily categorized into UVA, UVB, and UVC radiation. Solar radiation less than 290 nm does not reach at the earth’s surface due to the presence of O3 layer in stratospheric zone. But, last from few decades due to anthropogenic activities, the concentration of ozone layer decreases on stratospheric zone. As a consequence of that, UVB radiation levels are rising to 1% a year. Thus, the deleterious health effects on human beings (skin aging, cataracts, skin cancer, and immune suppression) are enhanced by UVR.
