Dr. Michele Farber, a dermatologist at Schweiger Dermatology Group, says that sometimes not scrubbing is better for sensitive skin, but adds that you do need to wash your legs if you have any cuts, are active, or sweat frequently. Regarding shaving, Dr. Vinod Nambudiri, a dermatologist with HCA Healthcare, recommends rinsing legs first, so the hair and skin are thoroughly soft and rinsed.
