NCT04875715
The purpose of this study is to analyze facial pigmentation and skin microbiome changes after topical almond oil application, compared to the use of topical hydroquinone.
NCT06142019
The aim of this project is to test the accuracy of pulse oximeters during mild, moderate and severe hypoxia. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxygen. This study will be done on healthy male or females between the age group of 18-50.
NCT06384092
The rationale of this study is to establish a robust method for assessing sun protection product efficacy in preventing erythema and tanning. Employing both artificial ultraviolet-A Irradiation and natural direct sunlight exposure, the investigation seeks to provide a reliable methodology, ensuring reproducibility and enabling a direct comparison between these methods. Meticulously determining optimal UV dosages, the study prioritizes inducing skin responses for evaluation while avoiding adverse effects like blistering. The localized validation of UV exposure techniques, tailored to the Indian population, contributes significantly to the field by addressing diverse skin types and environmental conditions. By incorporating both artificial and natural (direct sunlight) UV exposure methods, the study aspires to enhance the safety and effectiveness of future dermatological investigations, benefiting both the scientific community and the broader population.
NCT05779280
The purpose of this study is to asses the impact of topically applying a form of vitamin C known as tetrahexyldecyl Ascorbate (THDA) along with a novel anti-aging ingredient, acetyl zingerone, compared against applying THDA alone.
NCT03564808
MSCs one injected along with fat, regulate pigmentation over the contour defects of face
NCT02147756
The purpose of this study is to compare structural changes in the skin caused by the CO2RE device versus the Repair.
NCT00747162
The investigators plan to enroll 500 consecutive Subjects at a major trauma center for this study. For each patient, the body mass index (BMI), age, sex, diastolic pressure and mean arterial pressure (MAP) at time of measurements. Additional information including diseases such as diabetes and vascular disorders will be recorded. Social demographics including alcohol and tobacco use will be recorded. This is important as alcohol and tobacco use could also contribute to cardiovascular diseases. The skin pigmentation of each subject will be recorded. Two different methods will be used for this measurement. Each patient will be graded on a six point scale as described by Young (Young, 1997). Additionally, each subject will have their skin measured using a reflectance colorimeter. The colorimeter, DermaSpectrometer II (cyberDerm, Broomall, PA) uses visible light to measure the amount of light reflected off the skin. By measuring the light reflectance, the skin pigmentation can be measure (Clarys, 2000). Muscle oxygenation will be measured using a continuous dual wavelength near infrared spectrometer. Using the different absorption characteristics of deoxyhemoglobin and oxyhemoglobin, the concentration of oxyhemoglobin in the muscle at an approximate depth of 2.5 cm is determined. The INVOS cerebral oximeter (Somanetics, Troy, MI) will be used for all measurements.
