Depends.: The ability of skin to recover from stretching, depends on your age and condition of the skin generally. Usually, people over 30 lose the ability for skin to snap back due to age-related loss of elastin (by chronic sun damage). Some prescription skin programs can repair this, like Obagi Nu-Derm (Dermesse is generic equivalent and others). Wait & see. Surgery may be required to remove excess skin
