Are the results permanent?
You must take good care of your skin after the procedure. If you stress the skin by sunbathing, smoking or not taking proper care, etc, your skin will become damaged. Taking care of your skin and using quality maintenance and prevention products like a high SPF sun block will most certainly help you retain the rejuvenated, more youthful appearance.
You will of course, continue to age, but your wrinkles will be softened and your appearance made fresher depending upon the depth of the peel.
