My DD aged 8, has noticeable hair on her upper lip. She's started to be conscious of it and a few kids have teased her. Whilst I'll tackle the teasing separately, She's asked how to remove it, but I'm really not sure the best painless approach. I've had the issue all my life and as a child/teen it gave me such confidence issues. Are those Venus dermoplanning trimmers any good? I don't want to cause any pain, and not sure if bleaching it would help the problem (she also has such sensitive skin). Thanks!
