I Had Electrolysis 2 Weeks Ago and It Looks Like I Was Left with Hyperpigmentation, Is this Normal?

Hi.....My question is that i have been going for electrolysis the first 2 sessions were ok but what i notice with the first electrologist is that she would send me home very uneven from my upper lip she would either take more hair on one side than the other so i decided to go to another electrologist and boy do i regret it i dont know if she just worked on my upper lip too much time but i have very noticeable dark spots on my upper lip and it is very embarrasing it has only been 2 weeks
