Electrolysis permanently destroys germ cells responsible for hair growth by way of insertion of a fine probe in the hair follicle and the application of a current adjusted to each hair type and treatment area.  

Thanks to modern technology, Apilus electrolysis devices have revolutionized permanent hair removal treatments. The creators of Apilus have designed a state-of-the-art computerized electrolysis machine that limits the level of destruction within the hair follicle, targeting only germ cells. This consequently protects the skin and prevents new hair growth.

Apilus offers advanced technology with proven effectiveness in the field of permanent hair removal. Apilus electrolysis systems have demonstrated time and time again that they deliver more effective and more comfortable treatments with rapid permanent results.

Owing to its powerful circuits and stable currents, Apilus offers pinpoint precision capabilities and optimal settings that deliver the results you seek. You can finally say goodbye to unwanted hair, whether it be facial hair or body hair.

Apilus is the gentle way to 100% permanent hair removal!

Hello, My Name is Karen Belleville. I am 51 years old and the owner and founder of Bay State Electrolysis And Laser.

After graduating from Western New England College in 1991 with a B.S.B.A. in Marketing, I then graduated from the Electrology Institute Of New England in 2000 and became a licensed Registered Electrologist. I had the good fortune of purchasing an existing practice immediately upon becoming licensed and I have been going strong ever since. I am also certified by the Commonwealth to practice Laser Electrolysis,

I was blessed to grow up on a dairy farm in rural Vermont. I moved to Massachusetts when I went away to college in 1987 and have made Western Mass my home ever since. My husband and I have three wonderful children ages 27, 21, and 11. (No, that's not a typo!). Add a Lhasa Apso and a bunch of crazy chickens to the mix and that's my life!
