Hello, Welcome to healthcare magic. The rashes you have described can occur if you pull the hair too vigorously during waxing. Vigorous pulling can cause small blood capillaries in the skin to break causing these rashes. Avoid vigorous force while waxing. Ice packs will help to some extent. The marks will resolve on their own in 1-2 days. There is no need to worry. If you develop itchy bumps like pimple, then it may indicate an infection of the hair openings and you may require an antibiotic cream. Hope this helps you. Take care.
