The time you choose to epilate is all left for you. Once you think that the irritation that arises because of red bumps is becoming unbearable, then you can think of removing the hairs to become comfortable again. However, the time of the day to do that depends on you. Some people can do that in the morning when they are taking their shower. Most other people would prefer to do that in the evening because it is better they do that and have a rest. You should know your body system, and you can choose the best time to do that. A time that is suitable for you may not be ideal for other people.
