Yes, if you do it once in a while. No, if you do it constantly. If you use acrylic on your nails all the time, you'll eventually deal with some annoying side effects, such as weakened nails. Moreover, your nails will grow a lot harder than before, and they will be prone to breakage. A safer alternative is gel manicure since this substance is less harmful than acrylic when it comes to damaging your nailbed.
