The Journal of Cosmetic Dermatology has published a report claiming that topically applied caffeine is a succesful slimming agent. The reasearch was conducted by scientists at at the Federal University of Rio de Janiero. The team studied 99 women treated with a cream formulated with a 7 % caffeine solution twice daily for 30 days.
The researchers took measurements at the beginning and end of the study, to report that 80 % of the women had a reduction in the circumference of their upper and lower thighs and nearly 68 % saw a reduction in hip measurements.
The researchers also assessed cellulite changes with a handheld imaging instrument that reveals microcirculation in fat tissue. Imaging showed little change in cellulite even in the hips and thighs that slimmed down. Researchers speculated that the 30 day time period may have not been enough to measure cellulite.
