I had always had gel( cooling or aloe vera) after threading treatment, and it's a standard in the industry . Reason behind some people are alergic...This is not bgi number and they need to coomuncate ther allergy .I have very sensitve skin and this is really needed.
In addition one can not choose upper lip treading on booking, thankfully this was accommodated ,but its stressful as the beauticians usually are fully booked.
