If your artificial nails or the gel on your own nails are applied in a professional and correct way, it is completely painless. If you have a painful feeling during or after the treatment or if your nails are red after the treatment, your nail plate was probably damaged as a result of the incorrect filing of your nails. Unfortunately, this is a common mistake with less well-trained nail stylists! If this happens, we recommend that you change your nail stylist/nail studio as soon as possible.
