The most common body skin concern is loose inner upper arm and inner upper thigh skin, virtually always in women. Next in line are “jelly belly” skin and wrinkles above the knees.
One of the best ways to tackle loose belly skin is Thermage. Knees and inner thighs have shown a moderate response to Ulthera. Especially in combination with a radiofrequency device. Loose arm skin needs a combo of Ulthera, fractional resurfacing and, occasionally, diluted fillers such as Sculptra, injected with a microcannula.
