Don’t over think normal temporary side effects. I would need to see a quality picture of the area you are describing, flowers, in order to comment more.
Electrolysis is a very low risk cosmetic and medical procedure. Most side effects are temporary and heal within a short time.
Same with you, wander. It would be nice to see some quality photos of your pin prick holes that have never healed.
A professional Electrologist watches your skin reaction closely and knows how much is enough. Afterwards, we don’t know what the client is doing to the healing skin when they go home. Some clients are impeccable when it comes to following aftercare instructions and some ignore advice. I’m sure you did everything right, wander. Without knowing details on both sides, it’s hard to guess why you have pin prick marks that never healed? This shouldn’t be.
For smaller hairs on the upper lip, I like those fantastic Kelly probes made by Laurier. A size 3 IBP or even a 4 IBP are the best for those delicate hairs.
I just did a case tonight on the fine hairs if the lower lip and will post pictures later. I had a startle as I was working on her. The solid metal indifferent electrode she was holding fell to the floor and we both jumped. She said she fell asleep as I was working on her lip and her hand went limp. There is a numbing effect that occurs after a short while and the area doesn’t sting too bad. Mother Nature is wonderful, in combination with the right probe choice, of course!
