I used nail scissors on my chin hairs when getting this treated and snipped right up to the skin so no one saw a thing worked wonders. I don’t bother anymore since they are paler and not so noticeable.
I do still use cream remover for upper lip half way between going back for an appointment, as I go every 6 weeks now for other area’s I use the remover after about 3 weeks let it grow back in plus more and then go at the 6 week mark, sometimes longer at which state I’d just use scissors to trim rather than snip right back any regrowth. All women have hair on the upper lips so as long as its short and not too black I don’t think its too bad between sessions.
Cream removers last longer than shaving, it won’t take long if you stick with it. My electrolyisis told me to leave a 2 week gap from using the cream on the upper lip before coming to see her again and is fine wit it. Anything that isn’t removing the hair from the root.
