Flabby Arms – when to worry and how to fix them!
Flabby arms are due to a combination of factors associated with aging and genetics, including an increase in overall body fat mass (a greater portion of which localizes to the arms in some women due to genetics), loss of muscle mass in the arms associated with aging and reduced activity (causing the skin to hang more loosely on the upper arm) and a loss of elasticity in the skin due to both aging and sun damage from UV radiation, according to San Francisco dermatologist Dr. Richard Glogau.
