There isn’t anything available without side effects. Even if you use the waxing or other techniques, they too have side effects. Similarly, epilating can cause you redness, breakouts, swelling, ingrown hair, and more. But, you should not cut on using epilators by hearing these problems. There are also valid reasons why redness or swelling is caused by smooth skin. So, yes, epilators do have side effects, just like methods of removing the hair have.
