Microcurrent certification. Many esthetician schools will list the required services for your esthetician license to make it seem as though you are getting more for your money. However, most of the services and treatments they list are required by the state board. At ESI, we go above and beyond what is required in a standard 1000 hours program. We offer certifications that are not required, but are quite necessary in today’s esthetic world. Our microcurrent machine certification is not required by the state board, but is a wonderful asset to have. The best part about it is that it is that all of our additional certifications are available at no additional cost to our students. Everything is included in your tuition!
