Some people have rings that are so tightly stuck that even soap does not help, but dental floss works for them. Meanwhile, others find dental floss painful even with a mildly stuck ring, yet soap works well for very tight rings. Why is some skin more sensitive to dental floss? And what makes some people’s skin respond better to either soap or dental floss?
The overarching answer is “people are different”. But I suspect you want a more granular answer than that.
Depending on various factors like age, sex, hydration status, disease process, etc., some people’s skin is more elastic than others. People also have different pain tolerances. If you mix and match all of these factors, you’ll get people reacting differently to the same stimuli.
Is the dental floss method more likely to work on women because there is more fat in their fingers? And does having large knuckles also contribute to the pain caused by dental floss?
OP, are you downvoting yourself?
