Following treatment with injectables, such as Botox™ and Dysport, wrinkle reduction is currently measured by subjective individual appraisals and still photographs. New research using three-dimensional speckle tracking photogrammetry will allow physicians to analyze the movement of speckles displayed on a color-coded heat map, resulting in an accurate and objective measurement of wrinkle reduction and vertical stretch.
The use of photography to measure distances between objects is known as photogrammetry. In a recent study at the University of Pennsylvania, researchers randomly applied white foundation and black speckle makeup to patients before and after treatments using injectable fillers in the frown lines between the eyebrows. A comparison of the movement of the speckles over a two week period was tracked and analyzed resulting in precise measurements of the reduction of horizontal wrinkling and vertical stretch.
Through the comparison of pre-treatment and post-treatment heat maps, physicians will have the ability to objectively evaluate the specific measurement of wrinkle reduction which will assist in determining the ideal dosage of a particular injectable for maximum aesthetic benefit and effectiveness. Further research may determine specific therapeutic regimens for males and females and for people of different age groups.
