Comparison of the Effects of Carboxytherapy and Radiofrequency on Skin Rejuvenation

November 12, 2013 updated by: Adriana Clemente Mendonça
Carboxytherapy (CA) refers to the cutaneous and subcutaneous administration of carbon dioxide gas [CO2] for therapeutic purposes. Radiofrequency (RF) is a method that uses electric current to generate heat into the layers of the skin and the subcutaneous tissue. Both techniques are indicated to the treatment of skin laxity. The aim of this study was to compare the effects of CA an RF on human skin. Methods: Eight patients who underwent abdominoplasty surgery received a single procedure of both treatments. Untreated skin was used as control. In an area of 49 cm2 (7 x 7 cm) in the infra-umbilical region CA was performed on the right and RF on the left side. Sample collection period ranged from zero to 120 days. CA was administered at a velocity of 40 ml/min, and the total quantity of CO2 infused was approximately 20ml. RF was carried out in a temperature higher than 40ºC on the epidermis for 5 minutes after reaching this temperature.

Detailed Description

Untreated skin was used as control. In an area of 49 cm2 (7 x 7 cm) in the infra-umbilical region CA was performed on the right side and RF on the left side. CA was administered using the beveled end of a 30G ½ needle introduced in the skin in an angle of approximately 30ºC and delivered at a velocity of 40 mL/min. The total quantity of CO2 infused was approximately 20 mL (0,3 to 0,6 mL/kg of patient's body weight) encompassing the whole delimited are. For the RF treatment, the epidermal temperature was controlled using an infrared thermometer monitored to reach 40ºC and treatment time was of five minutes starting after having reached this temperature. Sample collection varied from zero to 120 days after application. The samples were then fixed, cut in paraffin (5 µm) and stained with Picro sirus and Weigert. Morphological analyses were acquired using a Zeiss Axiophot® microscope, and they were processed using Adobe Photoshop®.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
