Gel nails are a type of artificial nail. When compared to an acrylic nail, it can look more realistic. They generally last 10 to 12 days before requiring maintenance, and they take a little longer to do. Another advantage is that they don't have that killer odor, which makes the service a little more pleasant. 

There are two types of gel nails - "file-off" and "soak-off." Please consult with your nail technician as to which one is right for you.
