Waxing is a popular hair removal method and one can quickly remove large amount of hair from any part of the body, including the legs. However, many complain about large red bumps on the skin after waxing. This may occur due to a number of reasons, the most common being usage of poor quality wax. In some cases, application of wax to the sensitive skin can cause irritation and lead to pimples. However, waxing-induced pimples disappear within a couple of days, without any treatment.
