I agree with Joyce. I have been an electrologist for over 30 years and I have a Silhouet-Tone (S.T.) epilator and do not have preset settings.
The newest epilator called The Evolution 7HD sequential gives you full control of your treatments. Whether it’s with the manual or pre-programmed mode, this highly efficient device ensures a comfortable treatment (referenced from S.T. ad). This is not solicited just an example.
The epilator doesn’t matter, it’s the professional electrologist experience. It’s quality not quantity.
An electrologist should be licensed and or fully trained in electrology and her epilator. See the State Rules & Regulations where you live, there maybe a few states in USA, left that require little or no training. Some electrology training centers or schools offer a selection of epilators to view and work with for experience and knowledge. Massachusetts and New Hampshire has 1100 hours of training and take a state board exam and pass it to get your license.
As for the healing process the other replies have said it well, to give it weeks to heal and do not pick off the scabs. I would add after the treatment I like salt & warm water. Yes. It stings. Works amazing. Teaspoon of salt in your clean palm & mix with drops of warm water (paste consistency) and place on the treated area for a minute or two or so. Rinse well.
M21147 this is your face and skin, so if need be can you travel to get a great professional for permanent hair removal? If available see reviews on the place/electrologist or call a dermatologist for a referral.
Best wishes for happy zapping!
