About the bruising, sometimes the hair can be a bit wavy, curly, sallow or deep and/or if the probe or needle goes beyond or not beyond a follicle, it’s possible a small capillary or thread like vessel is nearby and can pop. This can cause bruising in some people. It can be yellow/blue color, but not limited too. For that particular hair or area that’s being treated, I do not want to say a poor insertion happened or a probe or needle was too small or large for the follicle or not, but it is something else to consider that may have happened. We electrologists have to do a lot of feeling and try to be as accurate as possible on the insertion, but sometimes it can feel right, but we can’t see under the skin, so it’s a feeling type process to get the root of the hair to disable it to stop growing. Thinner dry skin on the underneath area of the eyebrows can be another area that can bruise on a rare occasion. Lots of capillaries there too. The bruise fades out over a few weeks and some people can take longer, depending on how depth of the bruise.
For the electrolysis treatment, if someone applies numbing cream to the area before the treatment, it chases the blood away from the area for a short amount of time and this may help with less bruising and sensitivity. (Always check with Dr. or professional care before using these chemicals/products).
