Ok so I did an upper lip wax today which resulted in some skin lift on both sides. Uuugggh!! I made sure I held tight and at that the wax wasn't too warm. She did let me know that her skin is very sensitive. No known meds. Why does this happen if yr practicing good technique??. Do you just say it's a possibility when it comes to waxing? I plan on calling her tmro to see how she's doing - what should I say?
