Semi-Quantitative Histological Analysis of the Effect of Intense Pulsed Light (IPL) and Carbon Dioxide (CO<sub>2</sub>) Intradermic Injection on Fibroblast and Collagen Proliferation in the Skin of Wistar Rats

Abstract: Background: In recent years, so-called "non-ablative rejuvenation" has been carried out with the use of lasers or intense pulsed light (IPL) to stimulate collagen production by dermal fibroblasts. Intradermal infusion of CO 2 stimulates fibroblasts and the synthesis of collagen and elastin, contributing to the retraction of the skin and tissue rejuvenation. Objectives: To evaluate the effects of IPL and the intradermal infusion of CO 2 on fibroblast proliferation and collagen in the skin of female rats. Method… Show more

“…Other studies show that controlled administration of medical CO 2 into the subcutaneous tissue induces hypercapnia and decreases local pH, which elicits a strong vasodilator response through the relaxation of the pre-arteriolar smooth muscle on the site 2,6,25. Histological features in the repair process showed the proliferation of newly formed small blood vessels and fibroblasts 21. The tissue stretching during infusion induces a subclinical inflammation, which triggers the repair and tissue regeneration processes that induce the activation of macrophages, fibroblasts, and endothelial cells that stimulate neovascularization and remodeling of the extracellular matrix.…”

“…Subcision with CO 2 infusion allows for reach beyond the length of the needle is an advantage for larger scars, this is akin to the same principle when Carbon Dioxide therapy is being used for reducing irregularity from liposuction [4] and cellulite [7,13]. The distension of the tissue caused by the gas triggers tissue repair and regeneration processes with neovascularization and remodeling of the extracellular matrix [7] and this contributes to the final results of the scars being treated [10,14,15].…”

“…Вона є основним компонентом міжклітинного матриксу більшості тканин, особливо шкіри [4,16]. Еластин, фібриноген і колаген є основними елементами волокнистої дерми: еластичні волокна (1-3%) також відповідають за пружність шкіри, а колагенові (70-80%) -за її міцність і стійкість до механічних впливів [28,36].…”

“…Вміст колагену на одиницю площі шкіри зменшується на 1% на рік протягом життя: наявність вуглекислого газу активізує еритроцити для доставки великої кількості кисню до клітин, а також процеси метаболізму, регенерації та фізіологічні функції шкіри на рівні клітин [28].…”
