Hi! I only have 2 months of experience but I understand the anxiety that comes from an adverse reaction. The tiny scabs at the hair follicles are likely folliculitis. Folliculitis are not necessarily due to mistakes during the procedure. They are usually due to poor aftercare, such as sweating after the procedure, scratching/scrubbing treated areas, and using harsh chemicals on treated areas. They can be treated with bacitracin topicals.
