A light chemical peel improves skin texture and tone and lessens the appearance of fine wrinkles. The results are subtle but increase with repeated treatments. If you have a medium chemical peel, treated skin will be noticeably smoother. After a deep chemical peel, you'll see a dramatic improvement in the look and feel of treated areas. Results may not be permanent. Over time, age and new sun damage can lead to new lines and skin color changes. With all peels, the new skin is temporarily more sensitive to the sun. Talk with your doctor about how long to protect your skin from the sun.
